C1290 Scion Code - Steering Angle Sensor Zero Point Malfunction
Quick Answer
The Skid Control ECU (Brake Actuator Assembly) acquires steering sensor zero point every time the ignition switch is turned to ON and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. Common causes include Yaw rate and deceleration sensor zero point calibration incomplete, Poor adjustment of centered position of the steering wheel, Poor adjustment of front wheel alignment. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1290 Scion Description
If front wheel alignment or steering wheel position is adjusted without disconnecting the negative battery terminal, or if the yaw rate and acceleration sensor zero point is not acquired after the adjustments have been completed, the Skid Control ECU (Brake Actuator Assembly) detects the difference between the previous zero point and newly acquired zero point and outputs this Diagnostic Trouble Code (DTC) to indicate a poor adjustment.
The steering sensor zero point malfunction warning will be canceled by turning the ignition switch off.
What are the Possible Causes of the DTC C1290 Scion?
- Yaw rate and deceleration sensor zero point calibration incomplete
- Poor adjustment of centered position of the steering wheel
- Poor adjustment of front wheel alignment
