    Description of DTC code C1433 Generic

    The Steering Angle Sensor has the function of measuring the speed at which the steering wheel turns, as well as the steering wheel position angle. Generally, the location of this device is on the steering column and becomes an important part of the Electronic Stability Control (ESC System).

    The information from the Steering Angle Sensor is sent to the Electronic Control Unit (ECU) Slip Control through the Control Area Network (CAN) communication system. If erratic operation occurs in such a communication system, the steering angle sensor point fault diagnosis function detects it.

    DTC C1433 OBD2 is stored by the Slip Control ECU when, after monitoring the Steering Angle Sensor, it is detected that the Steering Angle Sensor has experienced a malfunction in its internal circuitry.

    Symptoms of fault code C1433 Generic

    • Check Engine light illuminates.
    • ABS warning lamp illuminated.

    Causes of OBD2 C1433 Generic

    The reasons for the C1433 OBDII fault code are as follows:

    • Steering Angle Sensor wiring may be in poor condition.
    • Steering Angle Sensor circuit electrical connections could be faulty.
    • The Steering Angle Sensor power supply or the sensor in question may be in poor condition.

    Possible solutions of the DTC code C1433 Generic

    To troubleshoot diagnostic code C1433 OBD2 you must do the following:

    • As a first step consult the Technical Service Bulletins.
