Mercury Mariner Check Engine Light Illumination

(12 reports)

The check engine light may come on due to failure of the Variable Camshaft Timing (VCT) solenoids. The VCT solenoids will need to be replaced if they are the reason the check engine light came on.

Same problem as others. Engine light goes on and off several different times and finally stays on. AutoZone told me it was some kind of timing issue. Took to my mechanic and he verified it is this same issue with the cam timing. Repair? Estimate $350.00 -
