1999 Honda Civic 4 cyl Two Wheel Drive Manual 135000 miles
I get a error code for insufficient fllow through EGR valve. I have cleaned the valve, verifed it does work electrically, cleaned ports on intake by inserting wire. At engine idle valve does not open. Red wire to solenoid shows around six volts and the yelllow/blue wire to lift sensor shows around six volts. Is valve supposed to open at idle speed? If so why isn't the solenoid getting the full 12 volts? If it doesn't open at idle when does it open? Suspect ECM not giving full voltage. Any advice?
