I have a 2002 Saturn ls1. I put a code reader on it and I need to remove and clean egr valve. How is this done

locate your EGR valve. Saturn EGR valves are usually located near the intake manifold and throttle body. carefully remove vacuum hoses from the valve. then unbolt it. Remove the EGR valve and discard the old gasket. the valve has 3 bolts on it, 2 in front and one in the backside. if you can not let it soak for a few hours, then clean with shop towels and cotton swabs to remove built up carbon deposits. replace EGR valve with a new gasket. Good-day!

Insufficient egr flow. Cooling fan does not run

Is your AC system charged and working? I believe the pcm will not activate the fan unless the AC system is operational.

I have a 2001 saturn L100 that has a code of PO404. Is this my EGR sensor? If so where is it located and can I clean it or does it have to be repaired?

EGR Valve is on the intake manifold on the right side rear by the shock tower. It's round, has a base similar to a diamond shape, and has a steel tube leading up to it's base area on the back of the rear intake manifold. You can take it off and clean it out with throttle body cleaner, and clean the tube, but I've never seen one plugged. If it's indeed bad then I'd replace it and get a new gasket. If you're not sure how to check it then you should reask and clarify that.

BTW... just because there's a code doesn't mean the valve is broken. Could be an electrical issue. Again, check and clarify please.

Quite easily take off the air breather tube then there is a cone shaped part with a connector on top at the back of the engine right by the accelerator cable 2 10mm bolts hold it on take off the 2 bolts and the valve comes off.

1999 saturn s series 4 cyl. has code po405 already replaced egr valve

Hi. This code has come up for two possible reasons. the actual new egr valve has become clogged by the increasing amount of carbon that has built up in the intake manifold. when replacing th egr valve, its a good rule of thumb to use a cleaning solution to cleanse the hole that the egr valve is inserted in. make sure you clean it thoroughly inside as well. This method is good but, it dosen't always work so, the next level of cleaning the intake is to remove it and clean it manually. the next possible issue could be that the wire connectors are worn. this is highly unusual but, it may be the issue here.

Please rate and god bless:)

1995 saturn sl2 code 32

Hi. The EGR valve is a very sensitive issue. Buying a used one will always result in a continuing fault code. I recommend purchasing a new EGR valve. Before you install it, be sure to clean the EGR housing thoroughly. there can be carbon build inside where this valve is inserted. this carbon will trip the code if its not cleaned out properly.

please rate and god bless.
