Error code 1320 on cars Nissan - one of the most common problems faced by model owners Qashqai, X-Trail, Juke and others. This error is related to the engine management system (ECU) and often causes panic among drivers, as it can be accompanied by a loss of power, unstable engine operation, or even a transition to emergency mode. In most cases the error P1320 (its alternative designation in diagnostic scanners) indicates a fault in the circuit ignition or crankshaft position sensor, but the exact cause requires detailed diagnosis.

In this article we will look at what exactly the error means 1320, what symptoms accompany it, and how to check possible malfunctions yourself. You'll also find step-by-step instructions to fix the problem, prevention tips, and answers to frequently asked questions. It is important to understand that ignoring this error can lead to serious engine damage, so you need to act quickly.

What does error 1320 mean on Nissan?

Code 1320 in the diagnostic system Nissan belongs to the category of errors associated with ignition system or engine synchronization. In most cases it stands for:

  • 🔧 Malfunction of the crankshaft position sensor circuit (CKP) — the signal from the sensor is missing or is outside the permissible values.
  • ⚡ Problems with ignition coils - open circuit, short circuit or unstable operation of one or more coils.
  • 🔄 Synchronization failure between crankshaft and camshaft — the engine cannot correctly determine the position of the pistons.
  • 📡 Communication error between ECU and other control units - for example, with a gearbox control unit.

Depending on model Nissan (For example, Qashqai J10/J11 or X-Trail T31/T32) the error can manifest itself in different ways. On some cars it is accompanied Check Engine light flashing, on others - by switching to emergency mode with speed limiting to 2000-3000 rpm. In rare cases, the engine may refuse to start at all.

⚠️ Attention: If the error 1320 appears along with other codes (for example, P0300 - misfire), this may indicate a complex malfunction that requires professional diagnostics.

The main causes of error 1320

Reasons for the error 1320 can be roughly divided into electric And mechanical. Below is a list of the most likely problems, sorted by frequency of occurrence:

Fault type Specific reason Symptoms
Electrical Malfunction of the crankshaft position sensor (CKP) The engine stalls, does not start, the error appears immediately after starting
Electrical Breakdown or break in the ignition coils Engine trouble, misfire, loss of power
Mechanical Worn or damaged crankshaft ring gear The error appears when the engine warms up, the speed is unstable
Electrical Oxidation of contacts in connectors ECU or sensors The error appears periodically, especially in humid weather.
Software Firmware failure ECU after updating or disconnecting the battery The engine is unstable, the error does not reset

Particular attention should be paid crankshaft position sensor - he most often becomes the culprit of the error 1320. This sensor transmits data about the position of the crankshaft to ECU, and if the signal disappears or is distorted, the control unit cannot correctly calculate the timing of ignition and fuel injection. On models Nissan with engines HR16DE, MR20DE or QR25DE The sensor is located next to the flywheel and is susceptible to contamination by metal shavings.

How to diagnose error 1320 yourself?

Before going to the service station, you can carry out preliminary diagnostics on your own. For this you will need diagnostic scanner (For example, ELM327 or Launch CReader) and a multimeter. Follow this algorithm:

  1. Read the error codes. Connect the scanner to the connector OBD-II (usually located under the steering wheel) and check whether there is, in addition to 1320 other errors. For example, P0340 (camshaft position sensor) is often paired with 1320.
  2. Check the crankshaft sensor.
    • 🔍 Disconnect the sensor connector and inspect the contacts for oxidation.
    • 📊 Measure the resistance of the sensor with a multimeter (the norm for most models Nissan — 500-1500 Ohm).
    • 🔌 Check the voltage at the connector with the ignition on (there should be 5 V between the positive and signal contacts).
  • Inspect the ignition coils. Remove the coils and check them for cracks, signs of breakdown or corrosion. Also measure the resistance of the primary and secondary windings.
  • Check the crankshaft ring gear. To do this, you will need to remove the starter or pan - inspect the ring for chips or worn teeth.

    • If you don't have experience with a multimeter, you can use an alternative method: reflash ECU to standard firmware. Sometimes it's a mistake 1320 occurs after unsuccessful chip tuning or battery disconnection. To do this:

    1. Скачайте стоковую прошивку для вашей модели (например, для Qashqai J11 с двигателем MR20DD).

    2. Подключитесь к ECU через K-Line или CAN-шину с помощью программы Nissan Consult III.
    

    3. Загрузите оригинальную прошивку и выполните сброс адаптаций.

    ⚠️ Attention: Incorrect firmware ECU can completely damage the unit. If you are not confident in your actions, entrust this procedure to professionals.

    Step-by-step instructions for resolving error 1320

    If the diagnostics have identified a specific problem, you can begin to fix it. Below is an algorithm of actions for the most common cases.

    1. Replacing the crankshaft position sensor

    If the sensor CKP defective (indicates an open or short circuit), it must be replaced. To do this:

    1. Disconnect the negative terminal of the battery.
    2. Remove the engine protective cover (if equipped).
    3. Disconnect the sensor connector and unscrew the mounting bolt (usually 10 mm).
    4. Remove the old sensor and install the new one, having first cleaned the seat from dirt.
    5. Connect the connector and check the operation of the engine.

    The cost of the original sensor for Nissan - from 1500 to 3000 rubles, depending on the model. Analogs (for example, Bosch or Denso) may be cheaper, but their reliability is lower.

    2. Repair or replacement of ignition coils

    If the problem is in the coils, proceed as follows:

    • 🔧 Remove the coils by unscrewing the mounting bolts (usually 8 or 10 mm).
    • 🔍 Inspect them for cracks, traces of breakdown or melting.
    • 📊 Check the resistance:
      • Primary winding: 0.5-1.0 Ohm.
      • Secondary winding: 6000-15000 Ohm.
    • 🔄 If the coil is faulty, replace it with a new one. On engines HR16DE And MR20DE coils are individual for each cylinder.

    Important: When replacing coils, always use original spare parts or high-quality analogues (for example, NGK or Beru). Cheap coils often fail after 10-20 thousand km.

    3. Cleaning or replacing the crankshaft ring gear

    If the problem is mechanical (wear or damage to the crown), more serious repairs will be required:

    1. Remove the starter or sump (depending on model).
    2. Inspect the ring gear for chips or wear.
    3. If the damage is minor, you can try cleaning the teeth with sandpaper.
    4. In case of serious defects, the flywheel or crankshaft will need to be replaced (which is expensive and time-consuming).

    This procedure is complex and requires special tools, so it is best to entrust it to specialists.

    💡

    If after replacing the sensor or coils there is an error 1320 remains, try resetting adaptations ECU using a diagnostic scanner. Sometimes the control unit needs to be retrained after replacing parts.

    Prevention of error 1320: how to avoid recurrence?

    To make a mistake 1320 did not return, follow these recommendations:

    • 🔧 Check the condition of the electrical wiring regularly. Oxidation of contacts or frayed wires can cause an unstable signal from the sensors.
    • ⚡ Use quality fuel. Bad gasoline leads to detonation, which accelerates wear of the crankshaft ring gear.
    • 🛠️ Change spark plugs and coils regularly. Recommended interval for most models Nissan — 30-50 thousand km.
    • 📡 Avoid deep puddles. If water gets on the sensors or ECU may cause a short circuit.
    • 🔄 Do not disconnect the battery unless necessary. This may reset adaptations ECU and cause synchronization errors.

    Also useful once every 10-15 thousand km reset errors using a scanner, even if the “Check Engine” is off. This helps to identify hidden problems at an early stage.

    What to do if error 1320 appears after washing the engine?

    If the error 1320 occurred after washing the engine compartment, most likely water got into the sensor connectors or ECU. Required:

    1. Disconnect all connectors and dry them with a hairdryer (not hot air!).

    2. Blow the area around with compressed air ECU (usually located behind the glove compartment or under the seat).

    3. Check the crankshaft sensor circuit for a short circuit.

    4. If the error does not disappear, contact a service station for in-depth diagnostics.

    When should you contact the service?

    Not all faults cause an error 1320, you can fix it yourself. Contact the service if:

    • 🔧 You replaced the crankshaft and coil sensor, but the error remains.
    • ⚡ The engine is extremely unstable or does not start at all.
    • 📊 The diagnostic scanner shows several errors at the same time (for example, 1320 + P0340 + P0300).
    • 🔄 Do you suspect problems with ECU (for example, after unsuccessful chip tuning).
    • 🛠️ The ring gear or flywheel needs to be replaced.

    The service will carry out deep diagnostics using professional equipment (for example, an oscilloscope to check sensor signals) and accurately determine the cause. Average cost of diagnosing an error 1320 in Moscow and regions - 1500-3000 rubles.

    ⚠️ Attention: If you ignore the error 1320, this may lead to engine overheating, detonation or even broken timing belt (on some models). Repairs in such cases cost tens of thousands of rubles.
    💡

    The most common cause of error 1320 is a malfunction of the crankshaft position sensor or ignition coils. Start diagnostics with them, and if the problem is not solved, check the ring gear and wiring.
