Summary
Service Action: Retrofit of the Engine Coolant Temperature Sensor. Internal corrosion could form in the engine coolant temperature sensor which is integrated into the thermostat housing (not replaceable). This corrosion leads to internal bridging of the contacts, which can cause an inaccurate engine temperature reading. This false reading could lead to difficulty in the engine starting or a "Service Engine Soon" lamp being illuminated.
