'92 2.3L EEC test
I got a check engine light and I ran an EEC running (R), memory (M), and engine off (O). Nothing for (R) but (M) (O); 72, 32, and 7.
(72) is: PCM re-initialized Possible electrical noise, case ground or intermittent VPWR problem – VPWR Diagnosis.
(32) is: EVR – EVP signal is/was low – EVR
PFE – PFE shows low pressure, EGR not seating or memory, not seating intermittently – PFE.
(7) could have some thing to do with the Thick Film Integrated Ignition System (TFI), not sure.
Please, would some one tell me if this is the correct interpretation of these codes, and what they mean?
