Possible causes

- Internal fault in the sensor control module
What you can do
- 1Read and note the code, clear it and road test to see whether it returns
- 2Follow the signal wires from the sensor and look for breaks, chafing and pinched sections
- 3Check the connectors in the signal wiring for oxide and loose contacts
- 4With diagnostic equipment, follow signal A in live data while turning the wheel and see whether the value sometimes drops out
- 5Stability control is off while the fault is present, so have a workshop repair it promptly if it returns
