DTC Set Criteria
- Engine coolant temperature was 44.6°F (7°C) or more immediately before engine was stopped at last drive.
- Engine coolant temperature was 44.6°F (7°C) or more when engine started.
- Engine coolant temperature fluctuates 1.8°F (1°C) after 5 minutes have passed since engine started. PCM will not count time when Volume Air Flow (VAF) sensor average output frequency is 70 Hz or less, or fuel is shut off.
- Engine coolant temperature fluctuates 1.8°F (1°C) after 5 minutes have passed since engine started. Time is not counted if intake air temperature is 140°F (60°C) or more, engine speed is less than 1500 RPM, volumetric efficiency is less than 25 percent, or fuel is being shut off. PCM runs monitor only once during drive cycle.
- Engine coolant temperature fluctuates 1.8°F (1°C) after 5 minutes have passed since engine started. Time is not counted during fuel shut-off operation.
- There is only 1 monitor during 1 drive cycle.
