: egr valve test?

03-20-05, 09:20 PM
Does anyone know of a way to bench test an egr valve? I got a service engine soon light, checked the codes and it came up pc1406. I took the egr valve off and cleaned it, being careful not to use too much solvent and mess up the electrical parts on the top of the valve. It had no carbon 'gunk' on it, basically just soot. The egr passages had soot, but no carbon 'gunk' in them. The pintle on the valve moves smoothly with no binding when operated by hand.

The car only kicks the 'ses' light on and displays "service emmisions system' when I am on the freeway for a few miles. It runs fine, other than an occasional stall when sitting at a light prior to cleaning the valve. It has not stalled since I cleaned the valve. I would hate to spend $120 for a new valve, and end up beign something else. Maybe it just needs a more thorough cleaning? Is there a way to disassemble it to get the guts of the valve cleaner? Any help is appreciated.:banghead:
