Hard Failures
WARNING: This page is about a different variant/trim than selected.
Most hard failures cause MIL to illuminate and remain illuminated until malfunction is repaired. If MIL illuminates and remains illuminated (light may flash) during vehicle operation, cause of malfunction must be determined. See DIAGNOSTIC PROCEDURE . If a sensor fails, PCM will use a substitute value in its calculations to continue engine operation. In this condition, vehicle is functional, but will most likely display degraded driveability.
