Crankshaft Position Sensor

Print

OPERATION

The Crankshaft Position (CKP) sensor provides a signal through the ignition module which the ECM uses as a reference to calculate rpm and crankshaft position.

TESTING

NOTE
The crankshaft sensor should be tested either cold 14-122°F (-10-50°C) or hot at 122-212°F (50-100°C).

  1. Using an ohmmeter, measure the resistance between terminals. Resistance cold should read 1630-2740 ohms and hot; 2060-3225 ohms.
  2.  
  3. If resistance is not within specification, the sensor may be faulty.
