engine code 332! Please HELP!

[ekafrawy]

I got an engine code 332 which is "insuficient EGR flow" I just replaced the egr valve, and disconected the battery for about 2 hours. Hooked it back up took the truck for a drive and 3 minutes later the check engine light came back on. same code 332. Now I know there are a couple of sensors for the egr valve that I should have replaced, but I am not ure which one. Is it the EGR position sensor or the EGR pressure sensor?

Not sure but it does sound like a vacuum problem. Is the vac hose in good condition and connected at both ends? Maybe someone else will help you out.

332 EGR did not open/respond during test or if memory code, did not open intermittantly

DPFE which is the pressure sensor. Very common to fail.
