Perform the Crankshaft Position System Variation Learn .
- If the scan tool displays NOT learned this ignition, inspect for the following conditions:
- A worn or damaged crankshaft or crankshaft bearings
- Debris between the CKP sensor and the reluctor wheel
- A damaged reluctor wheel
- Excessive crankshaft runout
- Any interference of the CKP sensor or CKP sensor signal to the control module
- If the control module is unable to complete the learn procedure, replace the control module.
