Nissan Error P1564: Complete Troubleshooting Guide

Error P1564 on cars Nissan - one of those problems that can unsettle even experienced car owners. This trouble code is related to the engine management system and often appears on models Qashqai, X-Trail, Juke And Note with gasoline engines HR16DE, MR20DE or diesel K9K. Unlike obvious errors like P0300 (misfires), P1564 signals problems in the throttle control circuit or incorrect operation of the electronic control unit (ECU), which requires an integrated approach to diagnosis.

Owners often encounter this error after unsuccessful chip tuning, battery replacement, or even a banal engine compartment wash. Symptoms can range from a floating idle to a complete loss of engine power. In this article we will look at all possible reasons errors P1564, we will offer step-by-step diagnostic instructions and indicate repair methods - from the simplest ECU reboot to replacing the throttle assembly. We will pay special attention to the nuances for specific models Nissan, where the elimination algorithm may differ.

What does error code P1564 mean on Nissan?

Code P1564 in the diagnostic system Nissan stands for "ASC (Accelerator Sensor Circuit) - malfunction of the throttle position sensor circuit". However, in practice this code can indicate a number of problems:

• 🔧 Throttle unit malfunction (mechanical wear, contamination or damage to connectors)
• 🔌 Wiring problems between the throttle valve and the ECU (breaks, short circuit, contact oxidation)
• 💻 Malfunctions of the electronic control unit (incorrect software, ECU memory corruption)
• ⚡ Unstable power supply (low voltage on-board network, problems with the battery or generator)

It is important to understand that P1564 - This is not an independent malfunction, but a consequence of other problems. For example, on Nissan Qashqai J10 with engine MR20DE this error often appears after replacing the throttle body, if it has not been damper adaptation through diagnostic equipment. On diesel X-Trail T31 with motor K9K The code may indicate a malfunction of the accelerator pedal or its sensors.

⚠️ Attention: If the error P1564 accompanied by P0100 (malfunction of the mass air flow sensor circuit), the problem most likely lies in a dirty throttle assembly or air leakage. In this case, cleaning the throttle may temporarily eliminate the symptoms, but without a comprehensive repair the error will return.

The main symptoms of error P1564

Manifestations of the error P1564 depend on model Nissan and engine type, but there are general signs that should alert you:

• 🚗 Unstable idle (speeds fluctuate in the range of 500–1500 rpm)
• 🛑 "Check Engine" light comes on (sometimes together with ESP or ABS indicator)
• 🏁 Dips during acceleration (the engine stalls or jerks when you press the gas)
• 🔄 Spontaneous shutdown of cruise control (on models with this option)
• 🚫 Switching to emergency mode (speed limit to 2000–3000 rpm)

On Nissan Juke with engine HR16DE error P1564 often appears after long off-road driving or in wet weather. Moisture entering the throttle assembly connectors causes corrosion of the contacts, which leads to an intermittent signal. On Nissan Note E12 with variator CVT this code may appear during sudden temperature changes, for example, after washing the engine in winter.

Model Nissan	Typical symptoms of P1564	Most likely cause
Qashqai J10/J11	Floating speed, jerking during acceleration	Throttle valve dirty or position sensor faulty
X-Trail T31/T32	"Check Engine" + loss of power	Wiring problems or oxidation of ECU contacts
Juke F15	Jerking at low speeds	Malfunction of the accelerator pedal or its sensors
Note E12	Spontaneous engine shutdown	ECU malfunctions after disconnecting the battery

Reasons for error P1564

To effectively resolve an error, you need to understand its root cause. Let's consider all possible scenarios, starting with the most likely:

1. Throttle valve dirty

On gasoline engines HR16DE And MR20DE Over time, the throttle assembly becomes covered with soot, which interferes with the normal operation of the damper. Even if it opens mechanically, the position sensor may produce incorrect signals. Especially relevant for used cars more than 100,000 km.

2. Malfunction of the throttle position sensor (TPS)

Sensor TPS (Throttle Position Sensor) may fail due to wear, moisture or mechanical damage. On Nissan often used contactless sensor, but even he is not immune from breakdowns. A sign of a malfunction is an abrupt change in the signal when you smoothly press the gas.

3. Problems with wiring or connectors

Oxidation of contacts in the throttle body or ECU connectors is a common cause. P1564 on cars older than 5 years. Machines operated in high humidity conditions are especially vulnerable. Check:

• 🔌 Connector on the throttle valve (contact often oxidizes +5V)
• 🔌 ECU connector (may be damaged during careless repairs)
• 🔌 Wiring harness from the damper to the control unit (grinding insulation)

4. ECU malfunctions

The electronic control unit may display an error P1564 for several reasons:

• 💾 Incorrect software (for example, after unsuccessful chip tuning)
• 🔋 Memory loss when disconnecting the battery without power support
• 🔥 Overheating or mechanical damage ECU boards

⚠️ Attention: If the error P1564 appeared after disconnecting the battery, do not rush to change the throttle assembly! First do reset ECU adaptations through a diagnostic scanner or manually (instructions below). In 60% of cases this solves the problem.

Diagnosing error P1564: step-by-step instructions

For an accurate diagnosis you will need diagnostic scanner (For example, Launch X431 or ELM327) and a multimeter. Follow this algorithm:

Step 1: Reading Error Codes

Connect the scanner to the connector OBD-II and consider all saved errors. Please note the accompanying codes:

• P0120 — malfunction of the throttle position sensor circuit
• P0220 — incorrect signal from the damper position sensor
• P0507 - high idle speed

Step 2: Check the throttle body

Remove the throttle assembly and inspect it:

• 🔍 Pollution: if black deposits are visible on the walls, cleaning is required
• 🔧 Mechanical damage: check the movement of the damper (should open smoothly)
• 🔌 Connector status: oxidation or damage to contacts

Step 3: Check the Throttle Position Sensor (TPS)

To check TPS:

1. Disconnect the sensor connector.
2. Measure the resistance between the contacts 1–2 And 2–3 (should change smoothly when the damper is opened).
3. Check the voltage at the contact 3 (must be 5V with the ignition on).

Step 4: Check Wiring

Use a multimeter in test mode to test the circuit between:

• 🔌 Throttle valve connector and ECU (contact 1 - mass, 2 - signal, 3 - food)
• 🔌 Accelerator pedal connector and ECU (on models with electronic pedal)

Step 5: ECU Diagnosis

If the previous steps did not reveal any problems, check:

• 💾 ECU firmware version (may require flashing)
• 🔋 Supply voltage on the block (should be 12V with the ignition on)
• 🔥 Presence of physical damage (melted elements, traces of corrosion)

How to fix error P1564: repair methods

Depending on the cause, solutions P1564 can range from simple cleaning to replacing expensive components. Let's consider all possible options:

1. Cleaning the throttle body

If the problem is contamination, follow these steps:

1. Remove the throttle assembly (disconnect the connector and unscrew the 4 bolts).
2. Clean the valve and channels with a special product (for example, Liqui Moly Pro-Line Drosselklappen-Reiniger).
3. Remove carbon deposits with a soft brush (do not use metal tools!).
4. Rinse the assembly and dry with compressed air.

⚠️ Attention: After cleaning the throttle valve Nissan Qashqai J11 And X-Trail T32 necessarily perform throttle adaptation via diagnostic scanner! Without this, the engine will operate unstably.

2. Replacing the throttle position sensor (TPS)

If the sensor is faulty:

1. Buy a new one TPS (original number for HR16DE — 22680-4M000).
2. Remove the old sensor (usually secured with 2-3 screws).
3. Install a new one and connect the connector.
4. Perform error reset and damper adaptation.

3. Wiring repair

If the problem is in the wires:

• 🔧 Oxidized contacts: Clean them with alcohol or a special cleaner (for example, Kontakt 60).
• 🔌 Wire breaks: Rebuild the circuit by soldering and heat shrinking.
• 🛠️ Damaged connectors: Replace with new ones (for example, throttle valve connector for Qashqai — 22770-4M000).

4. Flashing or replacing the ECU

If the error is caused by a malfunction in the control unit:

• 💾 Flashing: contact the service to install the latest software (cost - from 3,000 rubles).
• 🔄 Resetting adaptations: Execute via scanner (e.g. Nissan Consult III).
• 🔧 ECU replacement: as a last resort (the price of a new unit is from 20,000 rubles).

5. Alternative methods (if all else fails)

In rare cases, an error P1564 may be related to:

• ⚡ Faulty generator (low voltage in the on-board network).
• 🔋 Low battery (voltage below 11,8V).
• 🛠️ Incorrect operation of the immobilizer (on some models Nissan The ECU disables the throttle when the safety system fails).

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

In this case, it is most likely that moisture has entered the throttle valve or ECU connectors. Required:

1. Disconnect the battery for 1–2 hours to dry.

2. Remove the connectors and process them WD-40 or isopropyl alcohol.

3. Blow with compressed air (do not use a hair dryer - it can damage the plastic!).

4. Reset errors through the scanner.

If the problem persists, check the circuit for a short circuit.

Preventing error P1564

To avoid the error reappearing, follow these recommendations:

• 🔧 Clean the throttle body regularly (every 30,000–50,000 km).
• 🔌 Check the condition of the connectors at every maintenance (especially after washing the engine).
• 💾 Avoid "artisanal" chip tuning - incorrect ECU firmware often leads to P1564.
• ⚡ Monitor the on-board voltage (norm - 13,8–14,4V with the engine running).
• 🛠️ Use quality fuel — bad gasoline accelerates the formation of carbon deposits on the valve.

By car Nissan with the system E-Throttle (electronic throttle) it is especially important to avoid sudden battery disconnections. When replacing the battery, always use backup power supply (For example, starter charger) so that the ECU does not lose adaptation.

Frequently asked questions about error P1564

Is it possible to drive with P1564?

Technically possible, but not recommended. Error P1564 may lead to:

• 🚗 Unpredictable engine behavior (jerks, spontaneous shutdown).
• 🛑 Switching to emergency mode with power limitation.
• 🔥 Increased wear of the transmission (especially on models with a CVT CVT).

If the error appears for the first time, you can drive to a service center, but operating the car for a long time in this condition is dangerous.

How much does it cost to repair error P1564?

The cost depends on the reason:

Type of repair	Cost (RUB)
Cleaning the throttle valve	1 500–3 000
Replacing the TPS sensor	2,500–5,000 (with work)
Wiring repair	2 000–4 000
ECU flashing	3 000–8 000
ECU replacement	20 000–50 000

Is it possible to reset P1564 without a scanner?

Yes, but this is a temporary solution:

1. Disable negative battery terminal for 10–15 minutes.
2. Reconnect and start the engine.
3. Let it idle for 5-10 minutes (the ECU will learn itself).

However, without eliminating the cause, the error will return. On some models (for example, Nissan Juke) after such a reset it may be necessary throttle adaptation through a scanner.

Why does P1564 appear after replacing the battery?

When the battery is disconnected ECU loses adaptation throttle valve. By car Nissan with the system E-Throttle this results in:

• 🔄 Incorrect operation of the damper (floating speed).
• 💻 Error generation P1564 due to signal mismatch.

Solution: Execute reset adaptations through a diagnostic scanner or let the ECU learn itself (start the engine and let it idle for 10 minutes without pressing the gas).

Which Nissan models are most susceptible to P1564?

Most often the error occurs on:

• Nissan Qashqai J10/J11 (engines HR16DE, MR20DE)
• Nissan X-Trail T31/T32 (especially with CVT)
• Nissan Juke F15 (electronic gas pedal)
