What does this fault code mean?
Neutral position sensor B measures the angle at which the gear lever turns the input shaft to the gearbox, and the engine control module uses it while automatic stop-start is active. The code is set when the character of the signal from the sensor is wrong.
Possible causes
- Damaged neutral position sensor B
What you can do
- 1Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
- 2Check that the connector at neutral position sensor B is firmly seated and free from oxidation and looseness
- 3Check that the sensor is firmly fixed to the gearbox and is not damaged
- 4If you have a diagnostic tool, check in live data that the value for sensor B changes smoothly as the gear lever is moved between positions
- 5If the fault remains after these checks, have a workshop investigate neutral position sensor B
Symptoms you may notice3
- Automatic engine stop-start does not work while driving
- Automatic engine stop-start does not work at idle
- Starting and auto-start do not work
What the fault can affect1
- The automatic engine stop-start function is switched off
