Limp-In Mode

Note: If the Malfunction Indicator Lamp (MIL), is illuminated during vehicle operation, the vehicle has entered limp-in.

Purpose

Allows reduced vehicle operation, if one or more inputs fail. (The vehicle should be driven to a service facility as soon as possible.)

Operation

In Limp-in mode the PCM substitutes the input of an alternate sensor, for that of the failed sensor, and continues to monitor the faulty sensor input.

If the faulty sensor input returns within limits, and remains within limits long enough, the PCM will resume normal operation.
