It is commonly used in heavy-duty trucks from Paccar brands (Peterbilt, Kenworth) and select Freightliner models. A failing sensor can cause inaccurate gauge readings or prevent the engine protection system from warning of overheating, so it should be replaced when the gauge behaves erratically or the sensor is physically damaged.
