Air Gap Inspection

NOTE: Perform the following test only when directed.

1. Verify that the CKP sensor is installed properly.




2. Measure the air gap between the plate teeth and the CKP sensor using a feeler gauge.
- If not as specified, adjust the CKP sensor or inspect the plate teeth for being twisted and/or chipped.
- If any of the plate teeth is twisted and/or chipped, replace the plate. (See CKP POSITION TIMING RING/SERVICE AND REPAIR.)
