The EGR temperature sensor informs the PCM of temperature changes in the EGR passage.

With the engine cold, you can push on the EGR valve diaphragm. If it doesn't move or is hard to move, it indicates a stuck or defective EGR valve.

To ensure proper EGR system function, check hoses, connections, and inspect for damage, cracks, or leaks.

To test the EGR system, bring the engine to operating temperature, allow it to idle, then open and close the throttle to observe EGR valve stem movement; movement indicates proper system function. If the stem does not move, check the vacuum signal and connections.

On four-cylinder engines, you'll probably have to remove the air filter housing to access the EGR valve.

Component replacement involves removing and cleaning the EGR valve and mounting surfaces, removing deposits, and ensuring proper installation. For the EGR control solenoid, unplug electrical connectors, detach vacuum hoses, and remove the solenoid before reinstalling it. For the EGR temperature sensor, disconnect the electrical connector and unscrew the sensor before applying anti-seize to the threads and reinstalling it.
