Codes 32 and 33 ?
1997 Ford F-250 HD 460 engine this truck has 50 k on it and runs great but I need to pass emissions one last time and next year at 25 years old it’s exempt. So what are these codes or more importantly where are the parts that are causing the codes?
thanks for any help

32 EVP - (R) EGR not responding properly during test - EVP
EVR - (O, R, M) EVP signal is/was low - EVR
PFE - (R, M) PFE shows low pressure, EGR not seating or memory, not seating intermittently - PFE
33 ALL - (O, M) EGR did not open/ respond during test or if memory code, did not open intermittently - EVP EVR PFE
There are two way to check codes Key ON Engine OFF KOEO and KOER Key on Engine Running Above (R) means it was checked Running. (O) mean the truck was not running and (M) means a currently inactive code that happend but is not currently active.
You can google the acronyms to find the parts and where located for your engine.

Count the flashes again and keep in mind there will be 3 digit codes displayed. Also be aware there is a single "separator flash" between the end of the Key On Engine Off codes and the beginning of the Stored Code display.

That's why I was asking. As I understood it, 96/97MY trucks should all be OBD-II. I could be wrong. For all I know there's a way to do the paperclip trick with OBD-II, I've never thought to see if it's possible.
