Error P1564 on Nissan: decoding, causes and repairs

2. Software glitches

• 💻 Firmware conflict: after update ECU or immobilizer (for example, when replacing a key).
• 🔄 Resetting adaptations: If the throttle learning procedures have not been performed after disconnecting the battery.
• 🛠️ Incorrect chip tuning: the error may appear after “firmware for Euro-2” or other interventions in the factory software.

3. Mechanical problems

• 🔧 Worn or dirty throttle valve: especially relevant for cars with a mileage of more than 150,000 km.
• 🔩 Damage to connectors: cracks in plastic clips or corrosion of contacts.
• 🚘 Immobilizer malfunction: on models with system Nissan NATS (For example, Teana J32 or Murano Z51).

According to service center statistics, in 60% of cases error P1564 associated with electrical problems, in 30% - with software glitches, and only in 10% - with mechanical faults. However, without an accurate diagnosis it is impossible to determine the cause.

How to Diagnose Error P1564: Step-by-Step Instructions

Code diagnostics P1564 requires a systematic approach. Below are step-by-step instructions that will help identify the cause of the problem. To work you will need:

• 🔧 Multimeter (to check voltage and resistance).
• 🔌 Diagnostic scanner (for example, Launch X431 or ELM327 with the program Nissan DataScan).
• 🔍 Flashlight and magnifying glass (for inspecting contacts).

Step 1: Reading Error Codes

Connect the diagnostic scanner to the connector OBD-II (usually located under the steering wheel) and read all saved errors. Please note:

• If together with P1564 there are codes P060x (For example, P0603, P0605), the problem is most likely in ECU.
• If codes are present U1000 or U1010, check the connection between the control units (for example, ECU And BCM).

Step 2: Check ECU Power

Disconnect the connector ECU (usually located under the hood or in the cabin behind the glove compartment) and check:

• 🔋 Voltage on contacts +B And IGN (must be 12 V with the ignition on).
• 🔌 Presence of corrosion or oxidation on contacts.
• 🔍 Wiring integrity (are there any fractures or short circuits).

Check the voltage on the battery (should be ≥12.6 V)|Inspect fuses F19, F20, F25 (depending on the model)|Measure the voltage on the +B and IGN pins of the ECU connector|Check the ground of the control unit (resistance should be ≤0.5 Ohm)-->

Step 3: Throttle Sensor Diagnosis

Throttle position sensor (TPS) is one of the weak points in the system. To check it:

1. Remove the connector from the sensor and check the resistance between the contacts 1-2 And 2-3 (should change smoothly as the damper rotates).
2. Serve 5 V to the power pin and check the signal pin (the voltage should be in the range 0.5–4.5 V).

Step 4: Immobilizer Check

If the error P1564 accompanied by a flashing immobilizer indicator, perform the following steps:

• Try retraining the key (the procedure is described in the manual for your model).
• Check the integrity of the immobilizer antenna (located around the ignition switch).
• Check firmware versions ECU And BCM (they must be compatible).

How to resolve error P1564

The repair method depends on the identified cause. Below we will look at the most effective ways to resolve the error. P1564 for different scenarios.

1. Restore ECU power

If the problem is due to unstable voltage:

• 🔧 Clean the connector contacts ECU special liquid (for example, Contact Cleaner).
• 🔋 Check the battery and generator: the voltage at the terminals should be 13.8–14.4 V with the engine running.
• 🔌 Replace fuses F19 (10 A) and F20 (15 A) - they are responsible for power supply ECU on most models Nissan.

Critical information: On Nissan Qashqai J11 and X-Trail T32, fuse F25 (20 A) is responsible for the ECU main relay circuit. Its failure can simulate error P1564, although the real problem lies in a short circuit in the power supply.

2. Flashing or resetting the ECU

If the error is caused by a software glitch:

• 💻 Reset ECU by disconnecting the battery for 15–20 minutes (sometimes this is enough to reset temporary errors).
• 🔄 Update the firmware ECU up to the latest version using original software Nissan Consult.
• 🔧 If the error appears after chip tuning, return the factory firmware or contact a specialist to adjust the calibrations.

3. Repair or replace the throttle sensor

In case of malfunction TPS:

• 🔧 Clean the throttle body with carburetor cleaner (such as LIQUI MOLY Pro-Line).
• 🔍 Check the resistance of the sensor: between the contacts 1-2 And 2-3 it should change smoothly from 0.5 kOhm to 4.5 kOhm.
• 🚗 If the sensor is faulty, replace it with a new one (original numbers: 22680-4M000 for Qashqai, 22680-AL500 for X-Trail).

4. Troubleshooting immobilizer problems

If the error is related to NATS:

• 🔑 Retrain the keys according to the instructions for your model (for example, for Nissan Almera N16 the procedure takes ~10 minutes).
• 🔧 Check the immobilizer antenna for damage (it is located around the ignition switch).
• 💻 If the firmware ECU And BCM are incompatible, they will need to be synchronized using Nissan Consult III+.

⚠️ Attention: When replacing ECU or immobilizer on vehicles with the system NATS you will need to “bind” the new block to the keys. It is impossible to do this on your own - contact the service with an original scanner Nissan.

Common repair mistakes and how to avoid them

Many car owners make common mistakes when trying to fix P1564, which makes the problem worse. Let's look at the most common of them.

1. Ignoring associated error codes

If in memory ECU there are other codes (for example, P0605 or U1000), elimination only P1564 will not give results. Always analyze the complete list of errors and start with the most critical ones.

2. Replacement of sensors without testing

Often, owners immediately change the throttle sensor or ECUwithout checking the power and circuits. This leads to unnecessary expenses, since the problem may lie in the wiring or fuses.

⚠️ Attention: On Nissan Juke And Note replacement ECU Without re-flashing for existing keys, it will lead to complete blocking of the engine. In this case, the services of an official dealer will be required.

3. Incorrect reset of adaptations

After cleaning the throttle body or replacing the sensor, a learning procedure must be performed. If this is not done, the engine will operate unstably and the error P1564 may come back.

4. Use of non-original spare parts

Non-original sensors or control units may have different characteristics, which will lead to a conflict with the firmware. For example, a sensor TPS from Sensata may not be suitable for Nissan Pathfinder R51, even if outwardly identical to the original.

5. Neglecting to check weight

Bad mass on ECU or sensors often simulates an error P1564. Always check the resistance between the block ground and the body (should be ≤ 0.5 ohm).

By avoiding these mistakes, you will save time and money, and minimize the risk of the problem reoccurring.

Prevention of error P1564: how to prevent recurrence

To make a mistake P1564 did not return after repair, follow these recommendations:

• 🔧 Clean the throttle valve regularly (every 30,000 km) and check the condition of the sensor TPS.
• 🔋 Monitor the voltage of the on-board network: a low battery charge or a faulty generator can cause a failure ECU.
• 💻 Avoid “handicraft” chip tuning. If flashing is required, contact trusted specialists.
• 🔌 Periodically check the integrity of the wiring and contacts in the engine compartment, especially after washing or rain.
• 🔑 Keep the spare key away from sources of electromagnetic interference (for example, near a cell phone or microwave oven).

Pay special attention corrosion prevention on contacts. To do this:

1. Treat the connectors once a year ECU and sensors with special lubricant (for example, CRC Electronic Protector).
2. After washing the engine, blow out the engine compartment with compressed air.
3. In winter, check the condition of the seals on the lid ECU - they should not be cracked.

If your car often sits idle (for example, in winter), it is recommended to start the engine once a month and let it run for 10-15 minutes. This will help avoid battery drain and failure of electronic systems.
