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

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

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

Indication of the steering sensor zero point malfunction is canceled by turning the ignition switch OFF.
