Egr Vacuum Regulator Solenoid Circuit. Connect PicoScope Channel A to the vacuum solenoid switched earth circuit. January 31 2021 The EGR vacuum solenoid opens and closes a vacuum line to the EGR valve. Remove one of the jumper wires from the battery and install vacuum hoses on the two vacuum ports located on the EGR solenoid. If engine vacuum was present after the engine was started and was idling This indicates that the vacuum line is good and delivering the goods to the EGR Vacuum Regulator Solenoid.
The monitor looks for an EGR Vacuum Regulator circuit voltage that is inconsistent with the EGR Vacuum Regulator circuit commanded output state. If the computer detects an issue with the EGR solenoid circuit or system it will set off the Check Engine Light to notify the driver of the issue. The EGR cannot function at an idle or it will cause a very rough running engine or stalling. An illuminated Check Engine Light is another symptom of a bad or failing EGR control solenoid.

EGR VR solenoid circuit is open or shorted to ground.

An illuminated Check Engine Light is another symptom of a bad or failing EGR control solenoid. This test checks the electrical function of the Exhaust Gas Recirculation Vacuum Regulator EGRVR solenoid. It is meant to actuate at around a constant 2000 rpm. Remove one of the jumper wires from the battery and install vacuum hoses on the two vacuum ports located on the EGR solenoid. The test fails when the EGRVR circuit voltage is either too high or too low when compared to the expected voltage range. It uses engine vacuum to operate the EGR valve which opens and closes to allow the exhaust gases into the intake.
