Model Years Affected: 1990, 1991, 1992, 1993, 1994, 1995

Average Mileage: 120,120 mi (72,000 mi - 198,480 mi)


The cam sensor interrupter (magnet) may become demagnetized and/or fall off of the camshaft gear causing the Check Engine Light (Service Engine Soon) light to illuminate. On higher mileage vehicles it would be advisable to replace the timing chain and gears if this problem were to occur as the timing cover must be removed to replace the interrupter.
