DTC C1290/66 Steering Angle Sensor Zero Point Malfunction: Description

The skid control ECU obtains steering angle sensor zero point every time the ignition switch is turned to the ON position and the vehicle is driven at 22 mph (35 km/h) or more for approximately 5 seconds. The skid control ECU also stores the previous zero point.

If front wheel alignment or steering wheel position is adjusted without disconnecting the negative battery terminal, or if yaw rate and acceleration sensor zero point is not obtained after the adjustments have been completed, the skid control ECU detects the difference between the previous zero point and newly obtained zero point and outputs this DTC to indicate a poor adjustment.

Warning of the steering angle sensor zero point malfunction will be cancelled by turning the ignition switch off.
