California Vehicles (Digifant I)

Coolant Temperature Sensor:

1. With the ignition "OFF", remove the electrical connector at the coolant temperature sensor.
2. With a suitable volt/ohm meter, measure the resistance between the two terminals of the coolant temperature sensor.





^ Refer to the temperature sensor graph for the correct measurement.

If the correct measurement is not obtained replace the coolant temperature sensor.

NOTE: Because of its adaptive capability, the Digifant I control unit MUST be returned to its reference settings IF:

1. The coolant temperature sensor (blue connector) has been disconnected while the engine is running.

2. Any of these components have been replaced:
^ Digifant I control unit
^ Air flow sensor
^ Throttle valve potentiometer
^ Throttle body
