What does this fault code mean?
Steering wheel position signal R2 reads too high. The fault is intermittent and may have occurred earlier without being active now. Possible causes are poor contact, a short to supply voltage, an open circuit in the wiring, or a defective 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
What you can do
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the connector at the steering wheel angle sensor is firmly seated, clean and free from corrosion
- 3Inspect the wiring between the sensor and the control module for chafing and loose clips, especially where the cable moves
- 4With diagnostic equipment, follow the R2 signal in live data while turning the wheel slowly and check that the value follows the wheel smoothly
- 5Stability control is off while the fault is present, so have a workshop repair it promptly if it returns
