Checking the Gap

Checking the Gap

• Set the car on a lift and remove the front section of the exhaust pipe.
• Remove the rpm and timing sensor (see specific procedure).

1. Using tool no. 1.820.079.000 (A.2.0449), find dimension "A".

1. Using a gauge measure dimension "A".

1. Using a gauge measure dimension "B" on the sensor.

• Calculate the rpm and timing sensor gap and check that it is within the specified limits.

Engine Coolant Temperature Sensor (NTC)

This sensor detects the engine coolant temperature on the thermostatic cup through a thermistor (NTC) with a negative resistance coefficient, i.e. capable of lowering its resistance as the temperature increases. The electric signal obtained reaches the electronic control unit where it is used to correct the air-fuel mixture.

1. NTC resistance
2. Body
3. Connector

Removal/Refitting

• Disconnect the battery (-) terminal.

1. Disconnect the electrical connection from the engine coolant temperature sensor (NTC).
2. Slacken and remove the engine coolant temperature sensor from the thermostatic cup.
