Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
EGR Solenoid Vacuum Valve Assembly
- The resistance of each solenoid should be 32-64 ohms. Replace any solenoid which is not in this resistance range. The vent valve should allow flow when the solenoid is de-energized.
- The control valve should allow flow when the solenoid is energized. The valves may have a very small leakage rate during testing.
EGR Valve Position Sensor (EVP)
With the solenoid disconnected, check the resistance between the solenoid terminals. Resistance should be 51-108 ohms. Replace solenoid if not to specification. Ports should allow flow of air when solenoid is energized. Operational signal for solenoid is supplied by the ECA.
