Error code P1564 on Nissan: decoding, diagnosis and repair

Error code P1564 on cars Nissan - one of those problems that can unsettle even experienced car owners. It appears unexpectedly, often accompanied by unstable engine operation or even a transition to emergency mode. But what is hidden behind this mysterious combination of numbers and letters? Why does it occur on Qashqai, X-Trail, Juke and other models of the brand?

Unlike many other errors, P1564 directly connected to the engine management system - or rather, to throttle control unit (ETC — Electronic Throttle Control). This code signals a discrepancy between the actual position of the damper and what the electronic unit “expects” to see. It cannot be ignored: the consequences can vary from increased fuel consumption to a complete stop of the engine in motion.

In this article we will look at all possible reasons errors P1564, we will dwell in detail on diagnostic methods (including working with a diagnostic scanner and multimeter), and also give step-by-step instructions for troubleshooting. We will pay special attention to models Nissan Qashqai J10/J11, X-Trail T31/T32 And Note E11/E12where the problem occurs most often.

What does error code P1564 mean on Nissan?

Code P1564 in the diagnostic system Nissan stands for «Throttle Position Sensor — Performance Problem» (problem with throttle position sensor). However, in practice, the reason may lie not only in the sensor itself, but also in the components associated with it:

• 🔧 Throttle Position Sensor (TPS) malfunction - wear, contamination or mechanical damage.
• ⚡ Problems with wiring or connectors - oxidation of contacts, breaks or short circuit.
• 🖥️ Engine control unit (ECU) malfunctions — software errors or hardware malfunctions.
• 🔄 Misalignment or mechanical wear of the throttle assembly — the damper may “stick” or move jerkily.

It is important to understand that P1564 - this is not just a “sensor error”. This signal about a discrepancy between the expected and actual position of the damper, which can be caused by a chain of reasons. For example, on Nissan Qashqai 2.0 with engine MR20DE The problem often occurs after cleaning the throttle, if the damper has not been adapted.

On some models (for example, X-Trail T32 with QR25DE) the error may be accompanied by additional codes such as P0120 or P2101, which indicates a more serious problem with the throttle control system.

The main symptoms of error P1564

Error P1564 rarely appears “alone” - it is usually accompanied by noticeable changes in the behavior of the car. Here are the most common signs:

• ⚠️ "Check Engine" light comes on - the first and most obvious signal. On some models (for example, Nissan Juke) may flash.
• 🚗 Unstable idle speed — the engine “floats” from 500 to 1500 rpm or stalls.
• 🛣️ Jerks during acceleration — the car jerks, especially in low gears.
• 🔋 Switching to emergency mode — The ECU limits power, the speed does not rise above 2000–3000.
• 🔄 Slow response to the gas pedal — there is a “lag” when pressing.

On Nissan Note E12 with engine HR16DE error P1564 often appears in combination with increased fuel consumption (up to +2–3 liters per 100 km) and difficult start in cold weather. At the same time on Qashqai J11 with M9R (diesel) problem can lead to loss of traction at high speeds.

⚠️ Attention: If the error P1564 appears along with P0606 (ECU malfunction), do not try to reset it by simply reading it. This may indicate a critical control unit failure that requires professional diagnosis.

Symptom	Probable Cause	Models where it occurs most often
Idle speed fluctuates	Throttle valve dirty or TPS faulty	Qashqai J10, Note E11
Jerks during acceleration	Throttle misalignment or wiring problems	X-Trail T31, Juke F15
Emergency ECU mode	Critical error in ETC or ECU operation	Qashqai J11, X-Trail T32
Difficulty starting the engine	Incorrect adaptation of the damper after cleaning	Note E12, Almera N17

Causes of error P1564

To effectively resolve an error, you need to understand its root cause. Let's consider all possible scenarios, from the simplest to the most complex.

1. Throttle valve dirty

The most common cause on cars with mileage of more than 100,000 km. Carbon deposits, oil and dust accumulate on the walls of the damper, interfering with its smooth movement. This leads to incorrect sensor readings TPS and the emergence P1564.

This is especially true for engines with an exhaust gas recirculation system (EGR), such as MR20DE (Qashqai) or QR25DE (X-Trail). Contamination is aggravated if cleaning has previously been carried out without subsequent cleaning. damper adaptation.

2. Malfunction of the throttle position sensor (TPS)

Sensor TPS may fail for several reasons:

• 🔥 Overheating — the sensor is located next to the hot collector.
• 💧 Moisture ingress - for example, after washing the engine.
• 🕒 Natural wear and tear — the sensor resource is limited (usually 150–200 thousand km).

On Nissan Juke with engine HR16DE faulty TPS often leads to freezing speed at 1500–2000 rpm even after releasing the gas pedal.

3. Problems with wiring or connectors

Oxidation of contacts, breaks or short circuit in the sensor circuit TPS - common cause P1564. Connectors on models are especially vulnerable Nissan, operated in conditions of high humidity or salty roads.

You can check this with a multimeter:

1. Отсоедините разъём датчика TPS.
2. Переведите мультиметр в режим проверки сопротивления (200 Ом).
3. Прозвоните цепь между контактами датчика и ECU.

Normal resistance should be within 0.5–5 kOhm (See the manual for your model for exact values).

4. Malfunction of the engine control unit (ECU)

Less common, but apt: malfunctions ECU may lead to false alarms P1564. This is true for cars after unsuccessful chip tuning or during voltage surges in the on-board network.

On Nissan Qashqai J11 with M9R (diesel) the problem is sometimes solved ECU flashing official software. In extreme cases, the unit needs to be replaced.

5. Mechanical problems of the throttle assembly

Wear of the gears or bearings of the throttle assembly, as well as its deformation after an impact or unqualified repair, is another possible reason. On X-Trail T32 this may manifest itself as "biting" the damper when you press the gas hard.

How to check the mechanical condition of the throttle?

Remove the assembly and check the damper for smooth movement manually. It should move without jamming and return to its original position under the action of a spring. If resistance or play is felt, the unit must be replaced.

Diagnosing error P1564: step-by-step instructions

To pinpoint the cause P1564, a comprehensive diagnosis will be required. Below is an action algorithm that will help identify the problem even without a professional scanner.

Step 1: Read Errors

Use a diagnostic scanner (eg Launch CReader or ELM327) to read all stored errors. Please note the accompanying codes:

• P0120 — TPS circuit malfunction.
• P0220 — incorrect sensor signal.
• P2101 — problem with the throttle valve drive.

If there are several errors, start diagnostics with the “oldest” one (according to the date of recording in the ECU).

Step 2: Visual inspection of the throttle assembly

Remove the air duct and inspect the damper:

On Nissan Qashqai J10 common damper jamming due to the accumulation of oil deposits. In this case, cleaning with a special cleaner (for example, Liqui Moly Pro-Line Drosselklappen-Reiniger).

Step 3: Testing the TPS Sensor with a Multimeter

To test the sensor:

1. Disconnect the TPS connector.
2. Connect the multimeter in voltmeter mode to the contacts +5V (food) and mass.
3. Make sure the voltage is 4.8–5.2 V.
4. Connect the probes to the signal contact and ground, slowly open the damper manually.

The voltage should change smoothly from 0.3–0.7 V (flap closed) until 4.0–4.7 V (fully open). Sudden jumps or “dips” indicate a sensor malfunction.

Step 4: Check Wiring

Use a multimeter in continuity mode to check the circuit between TPS And ECU. Please note:

• 🔌 Oxidation of contacts in the connectors.
• 🔗 Breaks or short circuits in the wires.
• 🛠️ Quality of the "mass" on the body and engine.

On Nissan X-Trail T31 contact often oxidizes pin 37 in the ECU connector - this may cause P1564 and related errors.

Step 5: Throttle Adaptation

After cleaning or replacing the throttle body necessarily carry out adaptation (training) of the damper. On most models Nissan it's done like this:

1. Clear errors with a scanner.
2. Turn on the ignition (without starting the engine).
3. Wait 3 seconds.
4. Fully press and release the accelerator pedal 5 times within 5 seconds.
5. Wait 7 seconds.
6. Press the gas pedal all the way down and hold it for 10 seconds until the “Check Engine” flashes.
7. Release the pedal and turn off the ignition.

On Nissan Juke And Qashqai J11 may require adaptation via diagnostic scanner (e.g. Consult-III).

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

Depending on the cause, solutions P1564 can range from simple cleaning to replacement of components. Let's consider all the options.

1. Cleaning the throttle body

If the problem is carbon deposits, follow these steps:

1. Remove the air duct and unscrew the throttle assembly (usually 4 bolts).
2. Apply cleaner (eg Wynn's Drosselklappen Reiniger) on the damper and walls.
3. Clean carefully with a soft brush (do not use metal tools!).
4. Dry the assembly with compressed air.
5. Reinstall and swipe adaptation.

On Nissan Note E12 often required after cleaning reset adaptations through the scanner, otherwise the error will remain.

2. Replacing the throttle position sensor (TPS)

If the sensor is faulty, it must be replaced. For Nissan original sensors are suitable (22680-XXXX) or analogues from Hitachi, Denso. Average cost - 1500–3000 ₽.

When replacing:

• Disconnect the connector and unscrew the 2 sensor mounting bolts.
• Install the new sensor and tighten the bolts to torque 2–3 Nm.
• Adapt the damper.

⚠️ Attention: On Nissan Qashqai J11 with engine R9M (diesel) after replacing TPS may be required overwriting calibration data to the ECU via a dealer scanner.

3. Wiring repair

If the problem is in the wires or connectors:

• Clean oxidized contacts (use contact lubricant, for example, CRC 2-26).
• Replace damaged wires (cross section not less than 0.5 mm²).
• Check the ground on the engine and body - it must be securely screwed on.

On X-Trail T32 The wiring near the harness near the battery often frays - pay attention to this.

4. Replacement or repair of the throttle assembly

If the damper is mechanically damaged or worn, it must be replaced. Original node for Nissan Qashqai MR20DE costs about 8000–12000 ₽, analogues (for example, Ajusa) - cheaper (4000–6000 ₽).

When replacing:

1. Remove the old assembly and transfer to the new sensor TPS (if it is working).
2. Install the new unit, connect the connectors.
3. Adapt.

5. Flashing or replacing the ECU

If the problem is in the control unit, the options are:

• 🔄 Flashing official software (cost 3000–5000 ₽).
• 🔧 ECU repair (replacing capacitors, soldering tracks).
• 🆕 Replacing the block (original 20000–40000 ₽, used 8000–15000 ₽).

On Nissan Juke with HR16DE sometimes it helps reset adaptations via scanner Consult-III Plus.

Preventing error P1564

To avoid reappearance P1564, follow these guidelines:

• 🧹 Clean the throttle body regularly (every 50–60 thousand km).
• ⚡ Monitor your battery status - low voltage leads to ECU failures.
• 🔌 Check your contacts connectors for oxidation (especially after washing the engine).
• 🛢️ Use quality fuel - bad gasoline accelerates the formation of soot.
• 🔧 Don't ignore mistakes P0120, P0220 - they often precede P1564.

On Nissan X-Trail T32 with QR25DE It is recommended to check every 100 thousand km damper return spring condition — its weakening can lead to errors.

Frequently asked questions about error P1564

Is it possible to drive with P1564?

Short term - yes, but not recommended. The engine may go into limp mode, which will limit power and increase fuel consumption. On Nissan Qashqai J11 with M9R (diesel) long-term driving with this error can lead to turbine overheating.

How much does it cost to repair error P1564?

The cost depends on the reason:

• Throttle cleaning - 1000–2000 ₽.
• Replacing TPS - 2000–4000 ₽ (with work).
• Replacing the throttle assembly - 6000–12000 ₽.
• Diagnostics + ECU flashing - 3000–8000 ₽.

Can P1564 appear after cleaning the throttle body?

Yes, if not carried out damper adaptation. On Nissan Note E12 And Juke this is especially critical - the ECU “remembers” the old valve position, and after cleaning, a mismatch occurs.

What tools are needed to diagnose P1564?

Minimum set:

• Diagnostic scanner (ELM327, Launch X431).
• Multimeter (to check TPS and wiring).
• Throttle body cleaner (Liqui Moly, Wynn's).
• A set of socket wrenches (for removing the assembly).

Can P1564 go away on its own?

In rare cases - yes, if the cause was a temporary failure (for example, moisture in the connector). But usually the error is returned. On Nissan Almera N17 cases are known when P1564 disappeared after battery replacement (due to voltage sags).
