Ford EFI History and Operation - Pulling Trouble Codes, etc

Post by DPDISXR4Ti » Mon Nov 26, 2007 12:41 pm

Someone posted this on IMON, but I thought he was worth referencing here as well.

Lots of good, basic info on the evolution of the Ford EEC (PCM), inclusive of the EEC-IV PCM that our cars run.

Trouble codes and how to pull them are also included.

Good description of the sensors which provide inputs to the PCM, with one exception. Only a MAF and MAP sensors are described, and we use a VAF.
Concept is similar, though mode of calculating air mass is totally different with a VAF vs. MAF.
