Check engine light came on showing p2004. After tons of reading about this code I connected a vacuum gauge to the hose leading to the irmc solenoid from the intake and got a pressure of 20. There is no vacuum going to the actuator at any rpm therefore the solenoid isnt opening. I took the solenoid out and applied pressure to it with my vacuum pump. Then i connected voltage to it and the solenoid opened releasing the pressure... does this prove solenoid is good?
Then i attached the vacuum pump to the hose leading to the imrc actuator. I pumped it up and release it several times. I can hear the actuator and flaps moving each time.
Im assuming the problem is no electrical signal to open the solenoid is causing the p2004 code? I didnt get a chance to check the voltage coming from the plug. At what rpm should i be getting voltage?
