Fault code P1564 on Nissan Qashqai (especially on models J10 And J11 with gasoline engines MR20DD And HR16DE) is one of the most insidious mistakes that owners encounter. It signals problems in the engine management system, but its manifestations can vary from barely noticeable “twitching” at idle to the complete transition of the ECU to emergency mode. Unlike typical sensor errors (e.g. P0100 or P0300), P1564 often associated with hardware failures or software conflicts in the control unit, which makes its diagnosis a non-trivial task.

In this article we will look at all possible reasons errors P1564 - from banal oxidation of contacts to serious problems with ECU firmware, and we will also give step by step instructions for elimination. We will pay special attention specifics of Qashqai models 2014–2021where the error occurs most often. If your car suddenly loses power, the check light comes on and the scanner shows P1564 — this guide will help save time and money on diagnostics.

What does error P1564 mean on Nissan Qashqai?

Code P1564 in the diagnostic system Nissan stands for «Control Module Power Input Signal» — a problem with the power supply or signal at the input of the engine control unit (ECU). Unlike the universal OBD-II codes, this code is productive (manufacturer-specific), that is, its interpretation may differ slightly depending on the model and year of manufacture.

On Qashqai J10/J11 error P1564 usually indicates one of three things:

  • 🔌 Unstable power supply to the ECU (problems with wiring, fuses or relays).
  • 💻 Firmware failure or a data conflict in the control unit memory.
  • 🔧 Mechanical damage connectors, contact corrosion or short circuit.

Critical nuance: on a Qashqai with an MR20DD engine, error P1564 is often accompanied by code P0603 (ECU memory error), which indicates the need to reflash or replace the unit. At the same time, on HR16DE engines the problem is more often associated with the wiring to the crankshaft position sensor (CKP).

The main symptoms of error P1564

Manifestations of the error P1564 depend on its root cause, but there are a number typical signsthat should alert you:

  • ⚠️ "Check Engine" light comes on (sometimes flashes when moving).
  • 🚗 The engine goes into emergency mode (rev limit to 2–3 thousand, loss of power).
  • ⚡ Dips during acceleration or jerking at idle.
  • 🔄 Spontaneous shutdown of systems (such as air conditioning or cruise control).
  • 🛑 Engine stalls when stopped (typical for J11 with MR20DD).

On Qashqai 2017–2021 the error may appear sporadically - for example, only during a cold start or after a long trip. This complicates diagnostics, since the scanner does not always record the code during short-term failures.

📊 How often do you get error P1564?
  • Check Engine Light Is Constantly On
  • Only during acceleration
  • Occasionally, without a system
  • After washing or rain
  • Another option

Causes of P1564: from simple to complex

To effectively resolve an error, you need to understand it origins. We have ranked the reasons by frequency of occurrence on Nissan Qashqai:

  1. Oxidation or poor contact in ECU connectors (especially after washing or in damp weather).
  2. Fuse F19 (10A) faulty in the block under the hood (responsible for powering the ECU).
  3. Engine ground problems (corrosion of attachment points to the body).
  4. ECU firmware failure (often after an incorrect update or “rollback” of the version).
  5. Malfunction of the control unit itself (less common, but requires replacement).
  6. Short circuit in the crankshaft sensor circuit (typical for HR16DE).

On Qashqai J11 2014–2016 a common combination P1564 + P0335 (crankshaft position sensor error). This indicates problems with the wiring or the sensor itself, but not always - sometimes the fault is with the ECU, which does not process the signal correctly.

Why does the error appear after washing?

After washing the engine, moisture can penetrate the ECU or sensor connectors, causing short circuits. Contacts on Qashqai J10, where the ECU connector is located low. If the error appears after washing, first check:

  • 🔌 Tightness of the ECU connector (for the presence of water inside).
  • 💧 The condition of the rubber seals on the fuse box cover.
  • 🔋 Corrosion on battery terminals (can cause voltage drops).

Diagnosing error P1564: step-by-step instructions

Before you rush to change parts, go through full diagnostics according to this algorithm:

  1. Read all errors by scanner (not only P1564). Availability of additional codes (for example, P0603, P0335) will narrow down your search.
  2. Check fuse F19 (10A) in the block under the hood. It is responsible for powering the ECU. The fuse is intact, remove it and inspect the contacts for oxidation.
  3. Measure the voltage at the ECU:
    • 🔋 On contact 1 ECU connector (+12V power supply) must be 11.5–14.5V with the ignition on.
    • ⚡ On contact 2 (“mass”) resistance relative to the body should be 0 ohm.
  4. Check engine ground — clean the attachment points to the body (usually near the battery and on the gearbox).
  5. Inspect the ECU connector for moisture, oxidation or bent contacts. On Qashqai J11 The connector is located behind the battery.
  6. Test the crankshaft sensor (if there is an error P0335):
    • 🔍 The resistance of the sensor winding must be 500–700 Ohm.
    • 📊 Check the signal at idle speed with an oscilloscope (there should be a smooth sine wave).

Important! If after resetting the error P1564 it comes back right away - the problem is most likely in ECU firmware or the block itself. If the error appears after 10–30 minutes of driving, look for unstable contact or voltage sags.

How to fix error P1564: from simple to complex

Depending on the cause, repair methods vary from trivial to labor-intensive. Start with the simplest steps:

1. Cleaning contacts and checking fuses

In 30% of cases there is an error P1564 eliminated after:

  • 🧹 Cleaning fuse contacts F19 (use WD-40 or contact cleaner).
  • 🔧 Tightening the “massive” bolts on the engine (especially if they are rusty).
  • 💧 Drying the ECU connector (you can use a hair dryer or silica gel).
💡

If after cleaning the contacts the error disappeared, but returned after a few days, the problem is in the tightness. On Qashqai J10 Processing the ECU connector helps dielectric grease (For example, Liqui Moly Electronic-Spray).

2. Flashing the ECU

If the error is accompanied P0603, most likely the firmware has crashed or a data conflict has occurred. Solution:

  • 📥 Download original firmware for your ECU version (for example, for MR20DD it could be 2345A-xxx).
  • 💻 Use Nissan Consult III or Launch X431 for flashing. Do not use Chinese "pirated" firmware - this can kill the ECU.
  • ⚡ After flashing, run reset adaptations (via a scanner or by disconnecting the battery for 10 minutes).

Attention! ⚠️ Incorrect firmware can turn the ECU into a “brick”. If you are not sure, contact an authorized dealer or a trusted chip tuner.

3. ECU replacement or repair

If after all the manipulations the error remains and the ECU does not respond to diagnostics, the unit is faulty. Options:

  • 🔄 Buy used ECU from disassembly (only with the same firmware and version H/W).
  • 🛠️ Give the unit for repair (replacing the memory chip often helps).
  • 🆕 Buy a new ECU (expensive, but reliable). On Qashqai J11 the original block costs ~30–50 thousand rubles.

On Qashqai 2018+ with the system ProPILOT ECU replacement required binding to the immobilizer - Without this, the engine will not start. For this you need Nissan Consult IV or contact your dealer.

Repair cost: comparison table

Type of repair Cost (RUB) Time (hours) Warranty
Cleaning contacts + fuses 0–500 0.5–1 No
Flashing the ECU 3 000–8 000 1–2 1–3 months
ECU repair (chip replacement) 8 000–15 000 2–3 6–12 months
Replacing the ECU with a used one 15 000–25 000 1–2 Depends on the seller
Replacing the ECU with a new one (official) 30 000–50 000 1–3 1–2 years

Advice: Before purchasing a used ECU, be sure to check article number And firmware version (written on the block sticker). Mismatch will lead to new errors!

Prevention: How to avoid recurrence of P1564

To prevent the error from returning, follow these recommendations:

  • 🚿 Avoid pressure washing the engine — water gets into the ECU connectors.
  • 🔋 Check the on-board voltage regularly (must be 13.8–14.4V with the engine running).
  • 🔌 Process contacts special lubricants (for example, CRC 2-26).
  • 📱 Do not use cheap diagnostic adapters (they can “write” errors to the ECU).
  • ⚡ Monitor your battery status — voltage drops during startup provoke ECU failures.

Attention! ⚠️ On Qashqai J11 with the system Start/Stop Frequent engine start/stop cycles accelerate wear on ECU contacts. If you drive in traffic jams, disable this function through the menu Settings → Eco modes.

💡

If error P1564 appears after replacing the battery, the problem is the ECU adaptation reset. The procedure must be followed "Throttle Valve Relearn" through a diagnostic scanner.

FAQ: Frequently asked questions about error P1564

Is it possible to drive with P1564?

Short term - yes, but not recommended. The engine operates in emergency mode, which increases fuel consumption and the load on the transmission. On Qashqai with CVT Long driving with P1564 can lead to overheating of the box.

Will resetting the error through a scanner help?

Only temporarily. If the cause is not eliminated (for example, contact oxidation or firmware failure), the error will return after 10–100 km. The reset is only needed to check the results of the repair.

Is it possible to reflash the ECU myself?

Theoretically yes, but it is required original software and experience with Nissan Consult. An error during firmware can “kill” the unit. For Qashqai 2020+ Independent firmware is almost impossible due to security.

What should I do if the car does not start after replacing the ECU?

Most likely, the new unit is not linked to the immobilizer. On Qashqai J11 procedure required "NAT/IMMU Sync", which can only be performed by a dealer or service with Nissan Consult IV.

Why does the error only appear when it rains?

This indicates moisture has entered the ECU or sensor connectors. Check the tightness of the fuse box cover and treat the contacts dielectric grease. On Qashqai J10 The crankshaft sensor connector is often to blame - it is located low and becomes clogged with dirt.
