EGR Valve: Application and ID
EGR VALVE
The service-version Positive Temperature Co-efficient (PTC) type EGR valve, is provided with a temperature sensor threaded boss in the valve
housing itself (see image).
The new Negative Temperature Co-efficient (NTC) type sensor has a different thread (M10X1.25) to prevent confusion with the PTC-type (1/8"
NPTF thread) when installing.
