Detection Condition

DTC is set, when brake pedal is depressed (brake switch on), steering wheel is straight (power steering pressure switch is off) and actual engine speed is 100 RPM lower than expected for 14 seconds. PCM will not set DTC when atmospheric pressure is less than 21.3 in. Hg or intake air temperature is less than 14°F (-10°C). This is a continuous monitor. MIL is illuminated if PCM detects malfunction in 2 consecutive drive cycles.
