What does this fault code mean?

Gear position sensor B, which is part of the transmission control module (TCM), provides information about the selected gear position. The code shows that the signal from the sensor is too low, so the control module cannot read the gear position as it should. For this reason the engine is not allowed to start while the fault is present.

Possible causes

Contact resistance, oxidation or poor connection in connectors and joints
Signal wire shorted to ground
Misadjusted gear position sensor
Fault inside the TCM itself

What you can do

1Read and note the code, clear it and road test the car to see whether it returns
2Have a workshop check that the selector cable is correctly adjusted
3If you have a diagnostic tool: move the selector through all positions and check in live data that the selected position is shown
4If the fault returns, have a workshop check the signal wire to ground and the control module, and replace the transmission control module if needed

Symptoms you may notice3
