94 maxima VG30E code 32

[bigbobster]

Hello, new member here
I could use some help, please. I have been struggling trying to find out why a code 32 pops up a day or so after being reset. I have checked out the operation of the EGR vacuum solenoid and watched the egr valve open when vacuum was applied. Putting a vacuum gauge at the egr valve shows no vacuum when the motor is revved.

Perhaps I don't understand how to troubleshoot this EGR system. Is there anyone out there who can help?

Problem solved.

A hose had come off the throttle body vacuum port. It was well hidden.

Probably left off by the shop that did the fuel injectors.
