[Shotimes] 327 trouble code

[ROBERT SCHIRMER]

gentlemen

93 ATX, just started to throw out a check engine lite , when engine warms up.
It is throwing out a KOEO trouble code of 327, which according to the shotimes
trouble code list means DPFE output circuit below minimum test. My code
scanner book says EGR valve position sensor, Pressure feedback EGR (PFE)
sensor, or EGR Pressure transducer-signal voltage too low. This does NOT
appear to be the almighty EGR trouble code that all SHO members have at some
time in the past.

Based on past experience, any thoughts on this??

Thanks
Bob
