The fault code refers to the map thermostat jammed open. There may also be a complaint of low heat output with lower outside temperatures.
During engine warmup, the engine coolant does not reach operating temperature within the DME’s allowable time frame. This is caused by either a faulty thermostat inside the transmission oil heat exchanger or a faulty engine characteristic map thermostat.
