WARNING: This page is about a different car, the 2003 Cadillac Seville and 2003 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

The following conditions may cause this DTC to set:

The crankshaft reluctor wheel is damaged or improperly installed.
The sensor is coming in contact with the reluctor wheel.

Excess crankshaft end play will cause the CKP sensor reluctor wheel to move out of alignment with the CKP sensor. This could result in any of the following conditions:

A no start.
A start and stall.
Erratic performance.

An improperly installed crankshaft could cause excess crankshaft end play.

For an intermittent condition, see INTERMITTENT CONDITIONS under SELF-DIAGNOSTIC SYSTEM.
