Cam sensor interrupter failure on Buick Riviera

The camshaft position sensor interrupter (magnet) on the camshaft sprocket may fall off causing the check engine (SES) to illuminate. If this fault occurs on high mileage vehicles our technicians recommend to also replace the timing chain at the same time.
