Replacing the neutral sensor

Always follow the instructions in the "Learn/write neutral sensor" service function when replacing the neutral sensor. Unless the sensor is installed correctly its functionality will be either absent or inaccurate.

Be sure to comply with safety precautions for work on vehicles with MSA! 

Always ensure that the MSA has been switched off in order to prevent an automatic engine start during work in the engine compartment!
