Removing and refitting

Removing and refitting

Removing-refitting:

1. Lambda sensor
2. Detonation sensor
3. Vehicle speed sensor

1. Disconnect the electrical connector, then undo the Lambda sensor and remove it from its housing.
2. Disconnect the electrical connector, undo the bolt fixing the detonation sensor and remove it.
3. Disconnect the electrical connector and undo the casing for the vehicle speed sensor, removing it from its housing.

Removing-refitting coolant temperature sensor

• Disconnect the electrical connector from the sensor;
• undo the sensor removing it from its housing.

Take great care that the sensor is correctly refitted and over the electrical connection, since the information sent by the sensor is also used by the control unit for operating the radiator fan.
