Removing

- Position the vehicle on a lift.

- Disconnect the negative battery terminal.

1. Working from under the vehicle, disconnect engine rpm sensor electrical connection (1a) and undo retaining bolt (1b).

2. Remove the engine rpm sensor.

Refitting

1. Position engine rpm sensor (1a) in its housing, tighten retaining bolts (1b) and connect electrical connection (1c).

- Lower the lift.

- Connect the negative battery terminal.

- ENGINE RPM SENSOR IRREGULARITY LEARNING PROCEDURE.

- Start the engine.

- If the MIL warning light flashes on the control panel, the engine rpm sensor irregularity learning procedure must be carried out.

- With the engine running, wait for it to warm up (approx. 77°C).

- Press the accelerator at least 3 times until 600 rpm is reached; after each press, completely release the accelerator pedal and wait until the engine rpm comes down to the minimum value.

- If the MIL warning light is still flashing at the end of the operation, it means that the self-learning is not complete, therefore repeat the operations described above until the warning light stops flashing.

- Turn the engine off and wait a minute for the data to be stored in the permanent memory.

-The diagnostic instrument may be used to find out whether the sensor irregularity has been learnt or not, irrespective of the information displayed on the MIL warning light.
