EGR Control Solenoid: Testing and Inspection

EGR VACUUM REGULATOR SOLENOID VALVE CHECK
1. Disconnect the vacuum hose from the EGR vacuum regulator solenoid valve.

NOTE: When disconnecting the vacuum hose, always make sure that it can be reconnected at its original position.

2. Disconnect the harness connector.




3. Connect a hand vacuum pump to nipple (A) of the EGR vacuum regulator solenoid valve.




4. As described in the chart, check airtightness by applying a vacuum with voltage applied directly from the battery to the EGR vacuum regulator solenoid valve and without applying voltage.




5. Measure the resistance between the terminals of the EGR vacuum regulator solenoid valve.

Standard value: 29 - 35 Ohms [at 20 °C (68 °F)]

6. Replace the EGR vacuum regulator solenoid valve if resistance is out of specification.
