1993 vette with the dreaded 32 code.
I purchased a one owner 40th anni. w/12,000 miles back in Oct. of 17. I have had trouble with an ses light. Comes on only after several minutes at 70 mph+ on the highway. Replaced egr, and the egr solinoid as well as checking the egr vacumn circuit. Still has the ses light issue. What other sensors will throw this code? Also when the car was new with about 1200 miles on it the ecm was replaced for the same reason. A few monthes later the egr valve was replaced. I assume that fixed it because no mention of any more problems with the light. Will the prom go bad in the ecm? Don't know what else to check. Light almost never comes on in town or under 65mph. When you get a light you can pull of the road, stop the engine and restart and the light will reset and won't come on again for a few more miles. Check the codes I get 12 then 32. I mentioned the prom because as I understand it you swap the prom over to the new ecm when it is replaced. So I'm thinking that maybe the faulty part was never really replaced. Any help appreciated. mc
