DTC C1433 Steering Angle Sensor Internal Circuit
DESCRIPTION
Steering angle sensor signals are sent to the skid control ECU (master cylinder solenoid) via the CAN communication system. When there is a malfunction in the CAN communication system, it is detected by the steering angle sensor zero point malfunction diagnostic function.
| DTC Code | DTC Detection Condition | Trouble Area |
| C1433 |
Either condition is met:
With the IG1 terminal voltage 9.5 to 17.4 V, the skid control ECU receives an error signal from the steering sensor for 0.012 seconds.
An open in the sensor power supply circuit for 1 second or more.

WIRING DIAGRAM
Refer to DTC C1432 ().
INSPECTION PROCEDURE
When any of the speed sensors or the yaw rate sensor assembly has trouble, DTCs for the steering sensor may be stored even when the steering sensor is normal. When DTCs for the speed sensors or yaw rate sensor assembly are output together with DTCs for the steering sensor, inspect and repair the speed sensor and yaw rate sensor assembly first, and then inspect and repair the steering sensor.
