Error P1564 on Nissan: interpretation, causes and solutions

Error P1564 on cars Nissan - one of those problems that can baffle even experienced car owners. This trouble code is related to the engine management system and often appears on gasoline engine models such as Qashqai J10/J11, X-Trail T31/T32 or Juke F15. Unlike more obvious errors (e.g. P0300 — misfires), P1564 requires an integrated approach to diagnostics, as it can indicate both software failures and hardware malfunctions.

In this article we will look in detail at what is hidden behind the code. P1564, what symptoms accompany its appearance, and - most importantly - how to properly fix the problem without the risk of damaging the car’s electronic systems. We will pay special attention specifics of diagnostics on models with the system CONSULT-IIIwhere standard OBD-II scanners may provide incomplete information. If you encounter this error, prepare yourself: the path to a solution may include checking sensors, flashing the ECU, or even mechanical repairs.

What does error code P1564 mean on Nissan?

Code P1564 in the diagnostic system Nissan stands for "ASC (Accelerator Position Sensor) - circuit or signal fault". However, this definition is too general. In practice, the error may indicate:

• 🔧 Throttle Position Sensor (TPS) malfunction - the most common reason, especially on engines HR16DE And MR20DD.
• 🔌 Problems with wiring or connectors between the ECU and the sensor, including contact oxidation or breaks.
• 🖥️ Failures in ECU softwarewhen the controller incorrectly interprets signals from sensors.
• ⚙️ Mechanical malfunctions of the throttle assembly, for example, jamming of the damper or wear of the drive gears.

It is important to understand that P1564 often accompanied by other codes such as P0120 (TPS circuit malfunction) or P2135 (mismatch of accelerator pedal sensor signals). If there are additional errors in the ECU memory, diagnostics should begin with them - this will narrow the range of possible causes.

On some models (for example, Nissan Almera N16 or Primera P12) code P1564 may appear sporadically, especially in high humidity or after washing the engine. This is due to moisture getting into the sensor connectors. In such cases, the problem is often solved by drying and treating the contacts with special sprays (for example, CRC Contact Cleaner).

Symptoms of error P1564: how the problem manifests itself

Error P1564 rarely occurs “on its own” - it is usually accompanied by noticeable changes in the behavior of the car. Here are the most typical symptoms:

• 🚗 Floating idle speed — the engine can spontaneously increase or decrease speed in the range of 500–1500 rpm.
• ⚡ Jerks during acceleration, especially in low gears, when the ECU incorrectly interprets the throttle position.
• 🛑 Activating emergency mode (the icon lights up on the dashboard CHECK ENGINE, and engine power is limited).
• 🔄 Delayed response to the gas pedal — the car “stumbles” when you press the accelerator.
• 🔥 Increased fuel consumption due to suboptimal operation of the injection system.

On vehicles with variator (CVT)such as Nissan Qashqai J11 or X-Trail T32, error P1564 can lead to transmission jerking when switching modes D→R or R→D. This is due to the fact that the engine ECU and transmission ECU exchange load data, and an incorrect signal from the throttle position sensor distorts the CVT operation algorithms.

⚠️ Attention: If the error P1564 accompanied by constant lighting of the CHECK ENGINE lamp And engine failure to move to speeds above 3000 rpm, it is strictly not recommended to operate the vehicle. This can cause the catalytic converter to overheat and fail.

Interesting fact: on some Nissan with the system e-Pedal (For example, Leaf or Ariya) code P1564 may appear after updating the ECU firmware. In this case, the problem is often resolved by resetting the throttle adaptations through diagnostic equipment.

Diagnosing error P1564: step-by-step instructions

To pinpoint the cause of the error P1564, a comprehensive diagnosis will be required. Below is an action algorithm that will help narrow down the range of possible malfunctions.

1. Checking for related errors

Connect the scanner (for example, Launch X431 or Autel MaxiCOM) and read all fault codes. Pay special attention to:

• P0120, P0122, P0123 - Malfunction of the throttle position sensor (TPS) circuit.
• P0220, P0222, P0223 — problems with the accelerator pedal position sensor (APP).
• P2101, P2110 — malfunction of the throttle valve drive.

2. Visual inspection of sensors and wiring

Open the hood and inspect:

• 🔌 TPS sensor connector on the throttle body - check for oxidation, moisture or damaged contacts.
• 🔧 Throttle condition — whether there are any mechanical damages, jamming or carbon deposits.
• 📡 Wiring harness from the sensor to the ECU - make sure there are no chafing or short circuits.

3. Checking TPS sensor signals

For this you will need a multimeter. Connect it in voltage measurement mode to the sensor contacts (usually these are contacts A - food, B - signal, C - mass). With the ignition on and the throttle valve slowly opening, the voltage at the signal contact should change smoothly from 0.3–0.7 V (flap closed) until 4.0–4.7 V (fully open). Sudden surges or no change in voltage indicate a sensor malfunction.

4. Checking the throttle assembly

On some models Nissan (For example, Qashqai J10 with engine MR20DE) the throttle valve may become contaminated with carbon deposits, which leads to its jamming. To clean, use carburetor cleaner (e.g. Abro Carb Cleaner). Important: Do not use metal brushes - they can damage the special coating of the damper.

If the problem remains after cleaning, check the operation of the damper actuator. On engines with electronic throttle (e.g. HR16DE) the drive may fail due to wear of the gears or breakage of the motor windings. In this case, the throttle assembly assembly will need to be replaced.

5. Diagnostics of the ECU and firmware

If the sensors and wiring are ok, but there is an error P1564 continues to appear, the problem may lie in the ECU software. On some models (for example, Nissan Juke F15 with engine HR16DE) there are known cases when the error occurs after a firmware update. The solution is to roll back to the previous version of the software or flash it using original hardware CONSULT-III.

Model Nissan	Common cause P1564	Recommended Solution
Qashqai J10 (MR20DE)	Throttle valve contamination	Damper cleaning, adaptation via CONSULT-III
X-Trail T31 (QR25DE)	TPS sensor malfunction	Replacing the sensor, checking the wiring
Juke F15 (HR16DE)	ECU firmware failure	Flashing or rolling back to a previous version
Almera N16 (QG18DE)	Oxidation of sensor connectors	Processing contacts, replacing connectors

⚠️ Attention: On vehicles with the system NissanConnect (For example, Qashqai J11 or Ariya) error reset P1564 a regular OBD-II scanner may not work. In this case, a complete system reboot via the diagnostic connector is required. CONSULT-III.

How to Resolve Error P1564: Step-by-Step Solutions

How to resolve the error P1564 depends on its root cause. Below we will look at the most effective methods, starting with the simplest.

1. Cleaning the throttle body

If the reason lies in contamination of the throttle assembly, follow these steps:

1. Remove the air duct leading to the throttle valve.
2. Disconnect the TPS sensor connector (be sure to first remove the terminal from the battery!).
3. Apply carburetor cleaner to the choke and carefully remove carbon deposits using a soft cloth.
4. Check the movement of the damper - it should open and close without jamming.
5. Reinstall everything, connect the battery and perform throttle adaptation (if required).

On some models (for example, Nissan Note E12) After cleaning the damper, it may be necessary to reset adaptations through diagnostic equipment. Without this, the procedure may not produce results.

2. Replacing the throttle position sensor (TPS)

If the sensor is faulty, it must be replaced. When choosing a new sensor, pay attention to:

• 🔍 Article - must completely match the original (for example, 22680-4M000 for Qashqai J10).
• 🔧 Connector type — some sensors are similar in appearance, but have different pinouts.
• 📊 Characteristics - Resistance and voltage must match the specifications for your model.

After replacing the sensor, be sure to calibrate it. On most models Nissan this is done automatically when the ignition is turned on, but on some (for example, X-Trail T32) may require manual adaptation via CONSULT-III.

3. Repair or replacement of wiring

If the problem is an open or shorted wiring, follow these steps:

1. Test the wires from the TPS sensor to the ECU using a multimeter.
2. If a break is detected, find the location of the damage and repair the circuit (soldering + heat shrink).
3. If the contacts in the connectors become oxidized, clean them and treat them with a special lubricant (for example, Liqui Moly Kontakt-Spray).

On cars with high mileage (150,000+ km), the insulation of the wires in the harness that runs along the intake manifold often wears out. In this case, it is recommended to replace the harness completely, since local repairs may not provide long-term results.

4. Flashing the ECU

If the error P1564 caused by a firmware failure, it will need to be updated. To do this:

1. Connect diagnostic equipment CONSULT-III or its analogue (for example, Nissan DataScan).
2. Read the current firmware version and compare it with the latest available for your model.
3. If an update is available, flash the firmware following the manufacturer's instructions.

On models with the system NissanConnect (For example, Ariya or Qashqai J11) it is better to entrust flashing to an official dealer, since an incorrect update can lead to blocking of the ECU.

5. Replacing the throttle assembly

If all the previous methods did not help, and the diagnostics showed a malfunction of the damper drive or its mechanical part, the throttle assembly will need to be replaced. When choosing a new node, consider:

• 🔧 Engine type - nodes for HR16DE And MR20DD not interchangeable.
• 📋 Availability of adaptation — some components require mandatory calibration after installation.
• 🔄 Manufacturer — it is better to choose original spare parts (Nissan or Hitachi) or high-quality analogues (Denso, Bosch).

Cost of a new throttle assembly for popular models Nissan varies from 15,000 to 40,000 rubles. It is better to entrust the installation to professionals, since precise adherence to the tightening torque of the fasteners and correct connection of the connectors is required.

Common mistakes when diagnosing and repairing P1564

Many car owners and even some services make mistakes when eliminating the code P1564, which leads to a recurrence of the problem or worsening of the malfunction. Let's look at the most common mistakes.

1. Ignoring related errors

Error P1564 rarely appears alone. If there are other codes in the ECU memory (for example, P0120 or P2135), they also need to be eliminated. For example, if you replace the TPS sensor without fixing the problem with the accelerator pedal sensor (APP), the error will return.

2. Improper cleaning of the throttle body

A common mistake is the use of aggressive cleaners or metal brushes, which damage the special coating of the damper. This leads to accelerated carbon accumulation and re-seizing. Correct: Use only soft cloths and specialized cleaners (e.g. Wynn's Carb Cleaner).

3. Poor TPS sensor replacement

Many people save on sensors by buying cheap analogues from unknown brands. Such sensors often have a non-linear response or unstable resistance, which leads to the re-occurrence of the error. Recommendation: choose sensors from trusted manufacturers (Denso, Hitachi, Standard Motor Products).

4. Neglecting throttle adaptation

After cleaning or replacing the throttle body on many models Nissan adaptation is required. If this is not done, the ECU will receive incorrect data about the damper position, and the error P1564 will remain. On some vehicles (for example, X-Trail T32) adaptation is performed automatically, but on others (for example, Qashqai J10) it must be launched manually through diagnostic equipment.

5. Incorrect wiring diagnosis

When checking wiring, many limit themselves to visual inspection without measuring resistance and voltage. However, breaks or short circuits may be hidden under the insulation. Correct: test each wire from the sensor to the ECU using a multimeter.

⚠️ Attention: On vehicles with the system NissanConnect (For example, Ariya or Qashqai J11) incorrect connection of diagnostic equipment can lead to a malfunction of the multimedia system. Always use original adapters and follow the connection sequence.

6. Self-reflashing the ECU without experience

Reflashing the ECU is a responsible procedure that, if done incorrectly, can lead to complete blocking of the controller. Common mistakes:

• 🔌 Using non-original firmware from dubious sources.
• 🔋 Interruption of the firmware process (for example, due to a dead battery).
• 🖥️ Incompatibility of software versions with ECU hardware.

If you are not confident in your skills, it is better to contact specialists who have experience working with CONSULT-III or similar equipment.

Prevention of error P1564: how to avoid recurrence

To minimize the risk of the error occurring again P1564, follow these guidelines:

1. Regular cleaning of the throttle body

Clean the throttle body every 30,000–50,000 km, especially if the car is used in city traffic jams or over short distances. This will prevent carbon deposits from building up and causing the valve to stick.

2. Monitoring the condition of the air filter

A clogged air filter increases the load on the throttle body and can lead to accelerated wear. Change the filter according to the regulations (every 15,000–20,000 km) or more often if the car is operated in dusty conditions.

3. Protection of electrical connectors

Periodically inspect sensor connectors TPS And APP for oxidation or moisture ingress. For prevention, treat contacts with special compounds (for example, CRC Contact Cleaner or Liqui Moly Electronic-Spray).

4. Use of quality fuel

Low-quality gasoline with high sulfur content or additives can cause accelerated carbon formation on the throttle body and intake valves. Refuel at trusted gas stations and avoid using questionable additives.

5. Timely update of ECU firmware

If the manufacturer releases updates for your model's ECU, install them. This will avoid software glitches that can lead to errors. P1564. However, remember: the update should only be performed using original equipment and qualified personnel.

6. Diagnostics at the first sign of a malfunction

Do not ignore the first symptoms of the problem: floating speed, jerking during acceleration or fire CHECK ENGINE. The sooner a fault is identified and corrected, the lower the risk of serious breakdowns and expensive repairs.

What should I do if error P1564 appears after washing the engine?

If the error P1564 occurs after washing the engine compartment, most likely moisture has entered the sensor or ECU connectors. In this case:

1. Disconnect the battery terminal for 10-15 minutes.
2. Remove the connectors from the sensors TPS And APP, dry them with a hairdryer (without heating!) or compressed air.
3. Treat the contacts with a water-repellent spray (for example, WD-40 Specialist Contact Cleaner).
4. Check to see if moisture has entered the ECU (usually located under the windshield on the passenger side). If necessary, dry it too.
5. Connect the battery and reset the errors with the scanner.

If the problem persists, moisture-damaged sensors or wiring harnesses may need to be replaced.
