Our car has been showing a Cam sensor fault on the OBD. Mems3 1.8mpi.
I decided to change it.
The sensor is under the plug cover on to of the engine.
Undo the 3 10mm bolts and remove the cover.
Remove the 8mm bolt securing the sensor and pull free.
Disconnect the plug and pull it up out of the bracket.
Replace with the new 2 part sensor/lead.
