What this component controls or measures
Engine oil, coolant and fuel temperature sensors serve different control functions. Temperature readings should be interpreted for the correct circuit.
Match the Right Part to Your Equipment
Provide the exact sensor marking, sensing location and engine configuration.
Give the sensor marking, connector style and location on the engine. If there is a diagnostic code, include the code and the observed symptom rather than using the code as the part identification.
Replacement and diagnostic questions
Confirm connector, range and system use through correct part identification before replacement.
Check connection, mounting and test results before assuming a sensor or valve is the cause of a code or symptom. Sensor nomenclature can vary across engine families and is not proof of interchangeability.
