Failure Conditions

WARNING: This page is about a different car, the 1995 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

Engine at 4800 RPM or greater for .5 second with cruise control enabled and engaged. This may occur on slippery road conditions, extended wide open throttle acceleration, or for some mechanical problems (such as transaxle slippage). Under these conditions Code P066 will set and should be considered normal. Vehicle operator should be advised why cruise control disengaged. Clear code and road test vehicle to verify normal operation.
