Detection Condition

DTC is set when actual engine speed is 200 RPM more than programed target speed for more than 14 seconds with brake pedal depressed (brake switch is on) and front wheels in straight ahead position (Power Steering Pressure (PSP) switch is off). This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Pending code is available if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC is stored in PCM memory.

NOTE: If atmospheric pressure is less than 21.3 in. Hg or intake air temperature is less than 14°F (-10°C), PCM will not monitor this circuit.
