Code 332 in 1993 Ranger 2.3

[dorough]

Just bought a used '93 2.3 Ranger for my son and it's been giving me code 332 - EGR insufficient flow. I personally have a '94 2.3 Ranger and can clearly see the differences in the two when it comes to the EGR. The '93 doesn't have the control module mounted on the firewall. It just has the electrical connector and a vacuum line. So how does this thing work in the '93 model and how do I clear up the code short of replacing the EGR valve? Thanks in advance!

If it has a DPFE, it's a common problem.
Clogged egr ports will act the same way.

Problems solved: I hit the salvage yard today and pulled an EGR valve. It was a bit nasty but cleaned up really good and the valve moves freely. Got it home and pulled the old one off of my truck and found that the valve was stuck so bad that I couldn't free it at all. Popped the old replacement on & instantly the CEL went off. Woo!
