1993 F-150 Trouble Codes 327, 522, 112, 334
Does anyone have any idea what these codes probably mean? My thoughts are the EGR is bad and the sensor and also the IAT sensor.
The truck is a 1993 F-150 with an inline 6 (4.9) and its got a bunch of miles on it. I gotta get the check engine light off to pass good ol' California Smog!
Thanks in advance!

codes
acording to haynes ford pick-ups & bronco 1980 thru 1996 2wd 4wd:
code 327=evp or dpfe circuit below minimum voltage.
code 522= n/a in this book.
code 112= act sensor circuit grounded or reads 254<deg.>f.
code 334= egr closed voltage higher than expected.
good luck

Ill give it a shot....I looked the codes up in the book from the code reader I bought and it says different. Ill check everything first. I sure do like the OBD II alot easier. My Mustang is alot easier to figure out than this old dinosaur. hahahah

I had the same problems with my 93 XLT 302 and I just replaced all the vacuum lines (actually there were none to begin with) and all the codes went away! So deffinitely check your lines
