P1336 - FAULT CODE - OBD2

    Description of DTC code P1336 Generic

    The CKP (Crankshaft Position Sensor) is a device used in engines to record the speed at which the crankshaft rotates. Once this information is got, it is sent to the ECM (Engine Control Module) to have control of the fuel injection and the engine ignition. This sensor is usually composed of a rotating part, which is usually a disc, and a static part.

    The CKP sensor uses a space between two teeth of a reluctance ring to create a waveform that the ECM interprets as a reference point and to calculate ignition and fueling strategies. On the other hand, the ECM bases on the time interval between the on and off signals, which are created by the sensor and the ring, then it calculates the rotation speed of the engine.

    The diagnostic code P1336 OBDII refers to a malfunction in the Crankshaft Position Sensor. This is a manufacturer-specific code so its definition and meaning vary, although most of them indicate a failure in that sensor.

    Symptoms of fault code P1336 Generic

    • The Check Engine lamp is on.
    • Additional codes are configured next to the code P1336.
    • The engine fails during acceleration.
    • Idle irregularities.
    • The engine starts but after a few seconds, it stops unexpectedly.

    Causes of OBD2 P1336 Generic

    The reasons for establishing the DTC code P1336 OBD2 are

    • Crank Position Sensor wiring may be damaged.
    • The CKP sensor may be defective.
    • The starter motor may be in bad condition.
    • Possibly, there are deficiencies in the circuitry of the starting system.
    • The battery charge level may not be sufficient.

    Possible solutions of the DTC code P1336 Generic

    The steps to follow to correct the fault code P1336 OBDII are

    • See the Technical Service Bulletins.
    • With an automotive scanner, check if other DTC codes are stored, pay special attention if they are related to the ignition system. If this is the case, diagnose those codes.
    • Check the wiring, connectors, and other components of the CKP sensor If you discover damage such as wear, corrosion, or burns, make appropriate repairs.
    • Make electrical checks on the Crankshaft Position Sensor circuit and compare the actual values with those specified by the manufacturer. If inconsistencies are detected, make the respective adjustments.
    • Verify that the battery has the proper voltage for good system performance. If inconsistencies are found, check that it is not due to damage to the cables or electrical connections.
