Error P1564 on the dashboard Nissan - one of those problems that can unsettle even an experienced car owner. It signals a malfunction in the engine management system, but its decoding in manuals is often limited to the vague phrase “incorrect accelerator pedal position sensor signal" In practice, the reasons may lie either in banal oxidation of contacts or in serious problems with ECU (electronic control unit).

Especially often with P1564 Owners Face Nissan Qashqai J10/J11, X-Trail T31/T32 And Juke F15 with engines HR16DE, MR20DE And M9R. The error can manifest itself in different ways: from “failures” when you press the gas to the engine completely going into emergency mode. In this article we will look at all possible reasons, diagnostic methods (including testing with a multimeter) and step-by-step repair instructions - from cleaning contacts to flashing the ECU.

What does error P1564 mean on Nissan: official transcript

According to technical documentation Nissan, code P1564 stands for «Throttle Control Motor Relay Circuit» — a malfunction in the throttle control motor relay circuit. However, in practice this error is often accompanied by other codes such as:

  • 🔧 P0120 — malfunction of the throttle position sensor circuit;
  • ⚡ P0605 — ECU internal memory error;
  • 🚗 P2101 — malfunction of the throttle valve drive;
  • 🔌 P0507 - high idle speed.

This indicates that the problem may be complex. For example, on Nissan Almera N16 with engine QG15DE error P1564 often occurs after replacing the battery or resetting the terminals, when the ECU “loses” the throttle calibration. At the same time on Pathfinder R51 with VQ40DE it may indicate physical wear of the damper drive gears.

It is important to understand that P1564 is not a "universal" error — its manifestations and solutions depend on the model, year of manufacture and even the region where the car was assembled. For example, on European versions Qashqai 2010–2013 the problem is often solved by updating the ECU firmware, while on Asian Tiida During the same period, the sensor may need to be replaced.

The main causes of P1564: from simple to complex

Reasons for the error P1564 can be roughly divided into three categories: electric (problems with wiring, contacts), mechanical (wear of throttle parts) and software (ECU malfunctions). Let's take a closer look at them.

Fault type Specific reason Models where it occurs most often
Electric Oxidation of throttle valve connector contacts Qashqai J10, X-Trail T31
Electric Open or shorted wiring from the ECU to the throttle Juke F15, Note E12
Mechanical Wear of damper drive gears Pathfinder R51, Navara D40
Software ECU calibration failure after disconnecting the battery Almera N16, Tiida C11
Software Outdated ECU firmware (requires update) Qashqai J11 (until 2015)

The most common cause (about 60% of cases) is contact oxidation in the throttle assembly connector. This is due to the fact that on many models Nissan The connector is located in the lower part of the engine compartment, where it gets exposed to moisture and road dirt. For example, on X-Trail T32 with engine MR20DD contacts often become covered with a green coating after 3–4 years of operation.

The second most common problem is throttle adaptation failure after replacing the battery or disconnecting the terminals. In this case, the ECU “forgets” the basic parameters of the damper position, and it has to be “trained” again. On Juke And Qashqai with the system Drive-by-Wire (electronic gas pedal) this can lead to jerky acceleration.

If error P1564 appears after washing the engine or heavy rain, oxidized contacts are to blame in 90% of cases. Clean them with a special spray (for example, CRC Contact Cleaner) often solves the problem.

Diagnosing error P1564: step-by-step instructions

Before starting repairs, it is necessary to accurately determine the cause of the error. This will require OBD-II scanner (For example, ELM327 or Launch CReader) and a multimeter. Below is a step-by-step diagnostic algorithm.

  1. Count all errors. Connect the scanner and check if there is any P1564 other codes (for example, P0120 or P2101). Their presence will narrow the search for the problem.

  2. Visual inspection of the throttle assembly. Remove the air duct and inspect the connector for oxidation, damage, or traces of moisture. Pay attention to the condition of the wiring - whether there are any chafing or melting.

  3. Checking the voltage at the connector. Disconnect the connector from the throttle assembly and measure the voltage between the contacts with a multimeter +5V (usually red wire) and mass (black). It must be within 4.8–5.2 V.

  4. Flap motor resistance test. Measure the resistance between the motor contacts (usually white and green wires). Normal value - 1–10 Ohm. If the resistance tends to infinity - an open circuit, if it approaches zero - a short circuit.

If all parameters are normal, but the error remains, the problem may lie in ECU. In this case, resetting the throttle valve adaptation or reflashing the unit will help. On some models (for example, Qashqai J11) this requires special equipment, but Almera N16 or Tiida You can get by with a manual reset.

How to fix error P1564: repair methods

The method for eliminating the error depends on the diagnosed cause. Below are detailed instructions for each case.

1. Cleaning the throttle contacts

If the problem is oxidation, follow these steps:

  1. Disconnect the negative battery terminal.
  2. Remove the air duct and disconnect the connector from the throttle assembly.
  3. Clean the connector and throttle contacts with spray CRC Contact Cleaner or isopropyl alcohol.
  4. Blow out the connector with compressed air and reconnect.
  5. Reset the errors with the scanner and perform throttle adaptation.

2. Reset throttle adaptation

On most models Nissan adaptation can be done manually:

  1. Turn on the ignition (do not start the engine).
  2. Wait 3 seconds.
  3. Fully press and release the accelerator pedal five times within 5 seconds.
  4. Wait 7 seconds, then press the gas pedal all the way down and hold for 10 seconds.
  5. Release the pedal, turn off the ignition and wait 10 seconds.

After this, start the engine and check if the error disappears.

3. Replacing the throttle assembly or sensor

If the damper motor or position sensor fails, they will have to be replaced. On Qashqai J10 And X-Trail T31 throttle units are often installed from Renault (For example, 8200673527), since they are interchangeable. Average cost of a new node - 8,000–15,000 rubles.

4. Updating the ECU firmware

On models with outdated firmware (for example, Qashqai J11 before 2015) error P1564 can be fixed by updating the software. To do this you will need:

  • 🔌 Scanner with firmware function (for example, KTAG or Kess V2);
  • 💾 Official firmware from Nissan (can be found on forums or from dealers);
  • 🔧 Laptop with firmware program.

Independent firmware is risky - if there is an error, the ECU may become damaged. If you have no experience, it is better to turn to specialists.

What should I do if the error remains after replacing the throttle?

If after replacing the throttle assembly the error P1564 does not disappear, check:

1. The connector is connected correctly (are the contacts reversed).

2. Compatibility of the new unit with your model (sometimes ECU firmware for a new part is required).

3. Availability of updates for the ECU (on some Nissan after replacing the throttle, “binding” is required through diagnostic equipment).

Nissan Models Most Affected by P1564

Some models Nissan suffer from P1564 more often than others. This is due to the design features of the throttle units and the ECU. The table below contains a list of “problem” cars and typical causes of the error for each of them.

Model Engine Common cause P1564 Recommended Solution
Qashqai J10 (2007–2013) HR16DE, MR20DE Oxidation of throttle contacts, adaptation failure Cleaning contacts + reset adaptation
X-Trail T31 (2007–2013) MR20DE, M9R Wear of damper drive gears Replacing the throttle assembly
Juke F15 (2010–2019) HR16DE, MR16DDT Problems with the wiring from the ECU to the throttle Wiring test, repair or replacement of harness
Almera N16 (2000–2006) QG15DE, QG18DE Calibration failure after battery replacement Manual adaptation reset
Pathfinder R51 (2005–2012) VQ40DE Outdated ECU firmware Firmware update

On Nissan Qashqai J11 (2014–2021) and X-Trail T32 (2014–present) error P1564 It is less common, but can appear after unsuccessful chip tuning or installation of non-original parts. In this case, only diagnostics using specialized equipment will help.

💡

On Nissan with the system Drive-by-Wire (electronic gas pedal) error P1564 is often accompanied by “floating” speed or jerking during acceleration. This is due to the fact that the ECU cannot correctly determine the position of the damper.

Common repair mistakes and how to avoid them

Many car owners trying to fix P1564, make mistakes that only make the problem worse. Here are the most common of them:

⚠️ Attention: Never use WD-40 or other oil-based lubricants to clean throttle body contacts! They leave a film that attracts dust and accelerates oxidation. Use only specialized contact cleaners (e.g. CRC Contact Cleaner or Liqui Moly Kontaktreiniger).
  • 🔧 Ignore other errors. If in addition P1564 there is, for example, P0605 (ECU error), you need to fix it first, and only then work on the throttle.
  • ⚡ Incorrect adaptation reset. On some models (for example, Tiida) to reset it requires not 5, but 7 presses of the gas pedal. Always check the algorithm for your model!
  • 🚗 Installation of a non-original throttle assembly. Cheap analogues may not match in calibration, which will lead to the reappearance of the error.
  • 🔌 Checking wiring without disconnecting the battery. This may cause a short circuit and damage the ECU.

Another common mistake is an attempt to “reset” the ECU by removing the battery terminal. On many Nissan this resets all adaptations, including fuel maps and transmission parameters. As a result, after connecting the battery, new errors may appear, for example, P0300 (misfire).

⚠️ Attention: If you decide to update the ECU firmware yourself, never interrupt the file writing process! This can lead to a complete loss of communication with the unit and the need to replace it (the cost of a new ECU is from 30,000 rubles).

FAQ: Answers to frequently asked questions about error P1564

Is it possible to drive with P1564?

Technically possible, but not recommended. The error indicates incorrect operation of the throttle valve, which can lead to:

  • Jerking during acceleration;
  • Spontaneous increase in speed;
  • The engine goes into emergency mode (power limitation).

On some models (for example, Pathfinder R51) long drive with P1564 may lead to wear of the damper drive gears.

How much does a service repair cost?

The cost depends on the reason:

  • Diagnostics - 1,000–2,000 rubles;
  • Cleaning contacts - 500–1,500 rubles;
  • Replacing the throttle assembly - 8,000–15,000 rubles (with work);
  • ECU firmware - 3,000–10,000 rubles.

On Nissan With a warranty, it is better to contact an authorized dealer - independent repairs may lead to its loss.

Is it possible to reset P1564 without a scanner?

Yes, on some models. For example, on Almera N16 And Tiida You can reset the error by following these steps:

  1. Turn off the ignition.
  2. Press and hold the gas pedal for 10 seconds.
  3. Turn the ignition on (do not start the engine) and wait 3 seconds.
  4. Release the gas pedal and turn off the ignition.

However, this method does not work on all models. On Qashqai J11 And X-Trail T32 Reset requires a scanner.
