Well this can be caused by the thermostat being stuck open. The coolant temp will not come up to expected temp. It can also be caused by the fan being stuck on. Run the car and see if the fan stays on. If the fan is not stuck on it may well be the t-stat and replacing that should cause the check engine light to go off after a drive cycle.
