The hazard

Note: Certain 1997-99 vehicles in Ontario, Quebec and the Atlantic provinces and 1995-99 vehicles in all other provinces and territories. Moisture may enter the Powertrain Control Module (PCM) as a result of corrosion after extended exposure to road salt. This can lead to symptoms including illumination of the "Check Engine" light or the engine running rough. If these symptoms are ignored the engine may stall and may not be able to be restarted. Correction: Dealers will seal the Powertrain Control Module (PCM) in a protective shield/cover assembly.
