How to Solve Wuling P1396 Fault?
2 Answers
Wuling P1396 fault solution: The owner should clean the engine in time. Currently, there are two correct cleaning methods: 1. Go to a repair shop and use a special cleaning agent to clean carbon deposits. 2. Use a good fuel additive to clean the entire fuel system by yourself, including removing carbon deposits in the cylinder. The following is an introduction to the P1396 fault code: 1. The P1396 fault code means that the crankshaft position (CKP) sensor/engine speed sensor has an incorrect signal. The function of the crankshaft is to convert the up and down movement of the piston into rotational movement. 2. After the car fault is eliminated, the fault code needs to be cleared. When clearing the code, be sure to strictly follow the fault code clearing method specified for the specific model. Do not directly remove the negative ground wire to clear the fault code.
As an experienced auto mechanic, I've dealt with numerous Wuling P1396 faults, which typically indicate a crankshaft position sensor issue. I always start by checking if the sensor connector is loose or corroded, as oxidation commonly occurs after prolonged use. Then, I use a diagnostic scanner to read the trouble codes for details while observing whether the engine misfires or has difficulty starting—signal loss may affect ignition. Damaged wiring harnesses can also trigger this code, so carefully inspect the wiring from the sensor to the ECU for wear. If the connector and wiring are fine, the sensor itself is likely faulty and needs replacement. I recommend preparing tools like a multimeter to test voltage, but always prioritize safety by disconnecting power during repairs. After completing the repair, clear the codes and test to prevent false alarms. Untreated, such faults may lead to roadside breakdowns, so professional repair is advisable to avoid vehicle damage. Remember to regularly maintain and clean the engine compartment to reduce similar issues.
