What does this fault code mean?
The steering wheel angle sensor has registered that the signal from angle channel IY is too high. The fault is intermittent, meaning it has occurred at some point but may not be active right now. The cause lies in the sensor's circuits, in the connections to them, or in the sensor control module.
Possible causes
- Contact resistance or oxidation in connections and connectors
- Short circuit to voltage supply
- Open circuit in the wiring
- Defective control module for the steering wheel angle sensor
What you can do
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the connectors at the steering wheel angle sensor are secure and free from corrosion
- 3Follow the wiring from the sensor and look for chafing, pinching and loose clips
- 4With diagnostic equipment, follow the IY signal in live data while turning the wheel slowly; it should change smoothly
- 5The fault affects the stability system, so have a workshop repair it promptly if it returns
