Air Gap Inspection

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Verify that the CKP sensor is securely installed.
Using a thickness gauge, measure the air gap between the plate projections at the back of crankshaft pulley and the CKP sensor.
- If not within the specification, inspect the plate projections for cracks or bending.
  - If there is any malfunction, replace the plate.
