EGR Vacuum Regulator Solenoid: Testing and Inspection
The resistance of each solenoid should be between 32 and 64 ohms. If the solenoid is not within these values, the solenoid should be replaced.
The vent valve should flow when the solenoid is de-energized.
The control valve should flow air when the solenoid is energized.
For additional information, Refer to Powertrain Management/Computers and Control Systems/System Diagnosis
NOTE: The valves can be expected to have a very small leakage rate when energized or de-energized. This leakage is not measurable in the field and is
not detrimental to valve function.
