94 Check Engine Light- Codes pulled 332 &326

[UTAHEXPL]

Went to checkers after CEL came on to see if they could pull the codes for me. The guy couldn't get their scanner to work. So a friend thought he might have a scanner that would work, We pulled the codes 332 & 326. But didn't know what they were.

I've read that this is probably the EGR, and others say it's the PFE/DPFE. WHAT, HOW, & HELP. Are these easy fixs, or is there some where I need to be looking.

As I understand it from reading these forums, the DPFE is a known weak point in the EGR system. I had the same codes as you about a year ago and replaced the DPFE. I couldnt feel any difference, no mpg change or anything, but the codes did go away.

Do a search for DPFE in this forum and in your specific year forums and you'll learn more about the DPFE than you ever wanted to know.

They are incredibly easy to replace yourself.
