EGR problems

[Chalkmonkey]

I've got a problem with the Check Engine light. After the engines warms up, the CE light comes on (stays on most of the time). I ran the KOER test and produced a 332 code ( no EGR detected). I've tested the EGR Vaccum Regulator and it's working properly. I've also applied vaccum to the EGR valve and it appears to be allowing exhaust through the port. I replaced the the EGR pressure differential sensor about 10,000 miles back. Could it possible be bad again and if so how could it be checked(if at all). It's not setting the same code as when it was bad before.

Your "nostrils" are probably plugged up. Do a search in the Forum on nostrils, EGR and 332 to find the pictures of the nostrils and the description for cleaning them.

I'll give it a shot. Thanks!
