EGR Solenoid

Remove EGR solenoid harness connector. Measure resistance across EGR solenoid terminals with DVOM. Resistance should be 65-110 ohms. Set DVOM to 200k-ohm scale. Measure resistance between each solenoid terminal and ground or side of solenoid. Resistance should be greater than 10 k/ohms. If resistance is not as specified in either test, replace EGR solenoid.
