Where this component fits
A sensor or control-valve fault code does not necessarily prove the component has failed; wiring, supply conditions and mechanical system behavior can be involved.
Identify the correct part before ordering
Provide the EGR valve number, engine model and recorded fault conditions.
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
Distinguish valve, cooler, sensor and wiring issues before selecting the required replacement component.
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.
Common names and related search terms
Related terms include exhaust gas recirculation valve; EGR actuator. Sensor acronyms are useful search terms but are not a substitute for the OEM part number and connector description. Provide the complete part number and intended application when requesting a quote.
