INSPECT CRANKSHAFT POSITION SENSOR
Using an ohmmeter, measure the resistance between the terminals.
NOTE:
- "Cold" and "Hot" mean the temperature of the coils themselves.
- "Cold" is from -10 degrees C (14 degrees F) to 50 degrees C (122 degrees F) and "Hot" is from 50 degrees C (122 degrees F) to 100 degrees C (212 degrees F).
If the resistance is not as specified, replace the sensor.
