Circuit Description

WARNING: This page is about a different variant/trim than selected.

While engine is warming, PCM monitors ECT sensor to determine the amount of time it takes engine to reach coolant temperature required for closed-loop operation. DTC will set if PCM determines that ECT does not reach minimum coolant temperature required for closed-loop operation in a specified amount of time.

For duplication of DTC, ensure:

DTCs P0112, P0113, P0117 and P0118 are not set.
Engine is running.
ECT between -33°F (-36°C) and 104°F (40°C) at engine start-up.
IAT is greater than 19°F (-7°C).
Vehicle speed is greater than one MPH.
