Chrysler Front Wheel Drive Cars 6-CYL 1988-1995 Repair Information

Limp-In Mode


The limp-in mode is the attempt by the engine computer (PCM, ECU or SBEC) to compensate for the failure of certain components by substituting information from other sources. If the engine computer senses incorrect data or no data at all from the MAP sensor, throttle position sensor or coolant temperature sensor, the system is placed into limp-in mode and the CHECK ENGINE light on the instrument panel is activated. Although at the expense of performance and emission control efficiency, this mode will keep the vehicle driveable until service is obtained.
