C0445Steering Wheel Position Sensor Calibration
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- No accessible J2012 list contains C0445, and no manufacturer bulletin or service page using it could be found, so its exact meaning cannot be proven publicly. The title points to a steering wheel position sensor whose zero point was never learned or has been lost. Saab explains for the 9-5 that the sensor only knows straight ahead after a calibration, which is due after front-end work or a sensor swap. Mitsubishi resets both the sensor neutral point and the value stored in the stability unit after an alignment, and HELLA warns that a wrong zero upsets stability control. On the 2011 Saab 9-5, GM files this condition under C0710 symptom 42 instead. Expect the stability warning lamp and ESC out of action until the sensor is calibrated.
