1) Crankshaft Position Sensor Connector (CPS/CKP) testing
TESTING PROCEDURE 1991 – 2001 4.0L H.O. engines
A. Near the rear of intake manifold, disconnect sensor pigtail harness connector from main wiring harness.
B. Place an ohmmeter across terminals B and C (See Image). Ohmmeter should be set to 1K-to-1OK scale for this test.
C. The meter reading should be open (infinite resistance). Replace sensor if a low resistance is indicated.
2) The cam sensor is inside the distributor cap, it unplugs and comes right out.
3) Chrysler plugs have a red lock tab that slides and then you usually press down on another tab and then pull apart.
