Many owners Nissan Wingroad are faced with an unpleasant situation when the indicator light comes on on the dashboard Check Engine, and when connecting a diagnostic scanner a code appears P1320 (or 1320). This error indicates a failure in the ignition system control circuit, which can lead to unstable engine operation, increased fuel consumption, and even stopping the vehicle while moving. Ignoring the signal may result in severe damage to the catalytic converter due to unburned fuel.
It is important to understand that the code 1320 does not always mean failure of the ignition module itself. Often the problem lies in broken wiring, oxidation of contacts or incorrect operation of the crankshaft position sensor (CPS), which transmits a signal to the engine control unit (ECU). For Nissan Wingroad with series engines QG or GA This is one of the most common diagnostic tasks and requires a careful approach to the vehicle's electrical circuit.
The essence of the malfunction and the operation of the ignition system
Error 1320 in the system Nissan classified as "Crankshaft position sensor signal missing or faulty." The vehicle's ECU continuously monitors the signal from the DPKV to synchronize the timing of the spark and fuel injection. If the signal disappears for a short time or its shape is distorted, the computer detects a malfunction and turns on emergency operation, often limiting engine speed.
Unlike some other brands, where the error may indicate a misfire in a specific cylinder, Nissan Wingroad code 1320 most often indicates a global synchronization failure. This means that the computer has “lost” the crankshaft and does not understand what position the pistons are in. Without this information, it is impossible to correctly control the injectors and ignition coils, so the engine starts to run jerkily or stalls.
Feature Nissan is the use of a system where the signal from the DPKV is critical for the operation of the entire unit. If there is a signal, but it has interference, the error may only appear at certain engine speeds or temperatures. Therefore, diagnostics must be comprehensive and include checking both the sensor itself and the entire circuit from it to the processor.
The main causes of code P1320
There are several main scenarios that lead to the error 1320 on Nissan Wingroad. The most common cause is physical wear or damage crankshaft position sensor. Over time, the magnetic element inside the sensor can weaken and the winding can be destroyed by vibration and temperature changes, resulting in signal loss.
The second most common reason is problems with wiring and connectors. In the engine compartment Nissan Wingroad Wiring is exposed to high temperatures, oil and moisture. The contacts in the sensor connector may oxidize, and the wires themselves may rub against body parts or the engine block. An open circuit or short to ground will instantly cause a fault code to appear.
Often the problem lies in the ECU (Electronic Control Unit). In cars with high mileage, microcracks in soldering may occur inside the control unit or transistors responsible for processing sensor signals may fail. It is also worth considering that if there is a missing tooth on the crankshaft pulley or there is heavy dirt, the sensor will read incorrect information, which the ECU interprets as a circuit failure.
- ❌ DPKV malfunction: Complete or partial failure of the sensor itself.
- ❌ Wiring problems: Broken wires, oxidation of contacts in connectors.
- ❌ Dirt on the pulley: Metal shavings or oil on the crankshaft ring gear.
- ❌ ECU failure: Internal failure of the engine control unit.
Diagnostics and visual inspection
Before purchasing new parts, a thorough visual inspection is necessary. Start by finding the installation location crankshaft position sensor. On most engines Nissan Wingroad it is located at the bottom of the engine, near the flywheel or crankshaft pulley. Inspect the sensor housing for cracks and signs of oil leakage, as oil can get inside the housing and disrupt the operation of the sensing element.
Be sure to check the condition of the wiring harness going to the sensor. Pay special attention to where the wire enters the connector and areas where the wiring runs close to hot engine parts. If you see melted insulation or scuff marks, this is a clear sign that the wire may have shorted. Use a multimeter to check the continuity of the circuit: the resistance should not be infinite.
It is also worth inspecting the crankshaft ring gear, which is read by the sensor. If metal shavings, dirt or oil have accumulated there, the sensor will not be able to read pulses correctly. In some cases, the ring gear teeth may be mechanically damaged or missing teeth, requiring replacement of the pulley or flywheel itself.
⚠️ Attention: When inspecting the sensor and wiring, be sure to disconnect the negative terminal of the battery. A short circuit in the crankshaft position sensor circuit can lead to failure of the computer, the repair of which will cost much more than replacing the sensor itself.

Sensor and Circuit Test Methods
For accurate diagnosis, you must use a multimeter and, if possible, an oscilloscope. If you don't have an oscilloscope, you can check the resistance of the sensor. Disconnect the connector and measure the resistance between the sensor contacts. For most models Nissan normal value is from 500 to 1500 Ohm. If the readings fall outside these limits or show a break, the sensor must be replaced.
The second stage is checking the wiring. Turn on the ignition and measure the voltage at the connector on the vehicle side (without sensor). One of the wires should indicate a reference voltage (usually around 5V or 12V, depending on the circuit), and the second - mass. If there is no voltage, then the problem is in the wiring or the ECU itself. Also check that there is no short circuit to the housing.
If the electrical parameters are normal, but the error does not disappear, try replacing the sensor with a known good one. Sometimes a sensor may work fine on a desktop, but malfunction due to heat or vibration in operating mode. This is a so-called “floating” defect, which is difficult to identify without replacing the part. Do not forget to clean the installation area from dirt before installing the new sensor.
- 🔧 Resistance test: Use the multimeter in ohmmeter mode.
- 🔧 Voltage check: Measure the power at the connector with the ignition on.
- 🔧 Visual inspection: Look for signs of overheating, oil and mechanical damage.
☑️ Checking the crankshaft sensor circuit
What to do if the sensor is working, but the error is returned?
If the sensor and wiring are checked and ok, the problem may be in the ECU. Try resetting the error and driving a few kilometers. If the error returns immediately, the control unit may need to be reflashed or replaced. It is also worth checking the gap between the sensor and the ring gear, which should be within 0.5-1.5 mm.
Replacement and error reset procedure
Replacement crankshaft position sensor on Nissan Wingroad does not require complicated engine removal, but access may be difficult. You will need wrenches, a socket and possibly an extension. Remove the old sensor, clean the seat from dirt and oil so that the new sensor fits tightly and correctly. Install the new element, tighten the mounting bolt to the recommended torque, but do not overtighten it to avoid damaging the housing.
After installing a new sensor, you must reset the error. This can be done in several ways. The simplest is to disconnect the battery for 10-15 minutes. However, this method is not always effective, since the ECU may store the error in permanent memory. It is better to use a diagnostic scanner by connecting it to the OBD-II connector and selecting the “Clear Codes” or “Reset Errors” function.
If you are using a scanner, make sure it supports the protocols Nissan. After the reset, start the engine and let it idle for 5-10 minutes. Then drive the car in different modes (acceleration, braking, driving at a constant speed) to make sure that the error 1320 not returned. If the Check Engine light comes back on, the problem has not been completely resolved.
⚠️ Attention: Never try to reset the error by simply removing the ECU fuse for a short time. This may lead to loss of adaptation data (throttle learning, idle learning), which will lead to unstable engine operation after starting.
Proper replacement of the sensor and high-quality reset of errors through a diagnostic scanner is the key to successful repair of the ignition system.
Comparison of sensors and selection of spare parts
When selecting a crankshaft position sensor for Nissan Wingroad It is important not to make a mistake with the article number, since there are different engine modifications. Original is always the best option for maximum accuracy and durability. However, original spare parts can be expensive and take a long time to come from Japan. As an alternative, you can consider high-quality analogues from well-known brands, such as NTK, Denso or Hitachi.
Cheap Chinese sensors often have inaccurate magnetic field characteristics or poor quality wire insulation. The use of such parts may result in an error 1320 will be back within a week of use. Always check the markings on the sensor body and match them with your vehicle's part number. Pay attention to the presence of an o-ring that prevents oil from getting inside.
Below is a table comparing the main characteristics and features of the different types of sensors available in the market for Nissan Wingroad:
| Sensor type | Manufacturer | Average price | Service life | Features |
|---|---|---|---|---|
| Original | Nissan | High | 100,000+ km | Perfect compatibility, stable signal |
| Original (analog) | NTK / Denso | Average | 80,000+ km | Produced in the same factories as the original |
| Budget | Chinese brands | Low | 20,000 - 40,000 km | Risk of unstable operation, frequent errors |
| Refurbished | Different | Very low | Unpredictable | Not recommended for installation |
Complex cases and problems with the ECU
If all checks have shown that the sensor and wiring are working properly, but the error 1320 continues to appear, the problem may be hidden in the engine control unit (ECU) itself. In cars Nissan With a mileage of more than 150,000 km, the soldering inside the ECU often degrades or the output transistors fail. This requires professional diagnosis and possibly repair or replacement of the unit.
Sometimes the error occurs due to problems with the grounding of the ECU. Check all engine and body weight mounting points. Poor contact can create noise that is interpreted as a lack of signal from the crankshaft sensor. Clean the contacts from oxides and tighten the fastening bolts. It is also worth checking the condition of the fuses that supply power to the computer and ignition system.
In rare cases, the problem may be in the mechanical part of the engine. If the timing belt has jumped one tooth or is stretched, the valve timing is shifted, which can cause the sensor to malfunction. Check the condition of the timing belt and timing marks. If the belt is worn, it must be replaced along with the tension roller and pump.
- 🛠️ ECU repair: Resoldering of microcircuits or replacement of the control unit.
- 🛠️ Weight check: Cleaning and pulling of grounding contacts.
- 🛠️ Timing belt check: Checking the marks and inspecting the condition of the belt.
If you are planning on replacing the ECU, be sure to write down the VIN and current firmware. When installing a new unit, it may need to be programmed for a specific vehicle, otherwise the engine may not start.
Prevention and operating tips
To avoid the error reappearing 1320, it is recommended to carry out regular maintenance of the ignition system. Monitor the condition of the wiring in the engine compartment and, if necessary, replace worn sections of the harness. Use high-quality ignition wires and coils, as a breakdown in them can interfere with the operation of the sensors.
It is important to keep the engine clean. Dirt and oil on sensors and wires contribute to rapid oxidation of contacts and overheating of the insulation. When changing oil and filters, pay attention to cleaning the area around the crankshaft sensor. If you notice oil leaks at the bottom of the engine, fix them as soon as possible.
Use only high quality gasoline. Poor quality fuel can cause engine detonation and overheating, which negatively affects all electronic components, including sensors. Visit a service center regularly for computer diagnostics, even if the Check Engine light is not on. This will allow you to identify hidden problems at an early stage and avoid costly repairs.
⚠️ Attention: Error 1320 can be caused not only by electrical issues, but also by mechanical wear of the engine, so ignoring the problem is unacceptable.
