The differential between the temperature of the engine oil and the temperature of the engine coolant has exceeded the trip point. Also, the delay time has expired. There are no active codes for the sensors for the engine oil temperature and the engine coolant.System Response:The following event codes are logged according to the trip points for the temperature differential:
E337 (1) High Engine Oil to Engine Coolant Diff Temp (warning)
