What does this fault code mean?
The steering wheel angle signal R1 from the sensor reads too low. The fault is intermittent, so it may be absent now even if it was present before. Possible causes are poor connections, an open circuit or a short to ground, or a defective sensor element.
Possible causes
- Poor contact or oxidation in connections and connectors
- Open circuit in the wiring
- Short circuit to ground
- Defective SAS element in the sensor
What you can do

- 3With a multimeter, check that the wiring from the sensor has no contact with the body (ground)
- 4Look along the wiring from the sensor for breaks, chafing and pinched sections
- 5Stability control is off while the fault is present, so have a workshop repair it promptly if it returns
