C1290 2017 Toyota RAV4 Code - Steering Angle Sensor Zero Point Malfunction

C1290 indicates a "Steering Angle Sensor Zero Point Malfunction," meaning the vehicle's ABS or stability control system has detected an issue with the calibration of the steering angle sensor.

Symptoms may include the ABS warning light, traction control light, or stability control light being illuminated, as well as potential issues with stability or traction control functions.

The most common causes include improper or incomplete steering angle sensor calibration, a faulty steering angle sensor, issues with the ABS module, or wiring/connectivity problems.

While the vehicle may still be drivable, the ABS and stability control systems may not function properly, potentially increasing the risk of unsafe driving conditions in slippery or emergency situations.

The most common fix is recalibrating the steering angle sensor using a diagnostic scan tool. If recalibration doesn’t resolve the issue, the sensor or related wiring may need to be inspected and repaired.

Yes, a diagnostic scan tool capable of performing steering angle sensor recalibration is required to reset the code and ensure proper operation.

Ignoring the code may result in reduced or disabled ABS and stability control features, which could compromise safety in adverse driving conditions or during sudden maneuvers.

The cost can vary depending on the repair needed. Recalibration of the steering angle sensor typically costs $100–$200, while sensor replacement or wiring repairs may cost more.

Yes, a dead or recently replaced battery can sometimes cause the steering angle sensor to lose its calibration, triggering the C1290 code.

Ensure proper calibration of the steering angle sensor after wheel alignment, battery replacement, or suspension work, and regularly inspect the sensor and related wiring for damage.
