What does fault code P1336 mean?

[Nellie]

Fault code P1336 indicates a crankshaft position sensor target gear error. It is necessary to use a decoder to perform a target gear error learning procedure for the vehicle's crankshaft position sensor, so that the ECU can accurately determine the specific position of the crankshaft's operation and accordingly identify the top dead center of each cylinder. For vehicles newly equipped with an OBD system, if the gear learning has not been performed, the malfunction indicator light will illuminate after starting the engine, and fault code P1336 will be stored when checked with a decoder. If a new engine control unit has been replaced, the following learning procedure must be performed: 1. After starting the engine, wait until the engine temperature reaches 60 degrees Celsius, the vehicle has been running for more than 10 seconds, and all other loads on the vehicle are turned off; 2. Use a diagnostic tool (after upgrading) to enter the "Gear Self-Learning" option; 3. Follow the diagnostic tool's instructions to quickly press the accelerator pedal to the floor and keep it fully depressed. At this point, the ECM should perform the gear signal learning; 4. Turn off the engine, disconnect power for 10 seconds, then restart the engine to complete the learning process.
