A differential oil temperature reading that is missing or erratic, or a related warning light, can mean the sensor has failed. A damaged wire or a loose connector can also cause those readings, so they alone do not prove the sensor is at fault.
Fits
This sensor is a direct replacement built to fit and work like the original on specified vehicles, including the 2011-2026 Kenworth T680 and the 2011-2026 Kenworth T880.
