Modes of Operation

In this mode, the SMEC or SBEC compensates for the failure of certain components by substituting information from other sources. If the SMEC or SBEC senses incorrect data or no data at all from the MAP Sensor, Throttle Position Sensor, Charge Temperature Sensor, Coolant Temperature Sensor or battery voltage sensor, the system is placed into Limp In Mode and the Check Engine Lamp on instrument panel is activated.
