Failed Mass auto inspection

Not sure about the web, but there are more than 150 auto salvage yards in the State of Massachusetts. Most of us are listed in the yellow pages.

Are you sure that the concern is the PCM? It is rare that there is the need to replace these units. I'd want to be sure that this is, indded the problem before replacing it on a guess..... just a little friendly advice...

Might I ask why? Are you thinking that's the reason you failed an emissions test? Bob

I tried the junk yards. Hard part to find at the junk yard. I am sure Ford would have it but I was hoping to get a discounted part on the Web.

My computer is working, it passes if they stick the wand in the tailpipe. But Mass reads the codes from the computer now, no more wand, and the tester it seems can not communicate with the computer.

This actually failed several years back when Ford tried to update the computer with new firmware because of a recall, it could not be downloaded. I should have pushed back more at the time.

I'm not sure what a used PCM will set you back. If the cost is significant, you may want to ensure that all the wires to the DLC have continuity to wherever they go. It may sound like a daunting task but, IIRC, less than half the pins on the 16 pin DLC are actually used and even less than that are required for PCM network communication.

You can start by looking for pushed out pins in any connectors.

I'm off to school tomorrow night for three days so it will be difficult for me to find time to write up a pin out (and my job prohibits me from doing a cut and paste on shop manual content)... this may be a time where an AllData subscription might help you.

As an afterthought.... Blue Streak (Standard Motor Products) used to offer a reconditioning service. I'm not sure if they still do but it's worth a look. I only tried them once and was disappointed but that may be the result of the nature of the concern I was addressing.

downloaded.

I got one from Alberts Used Auto Parts USA-CT. It was the computer. Thanks for everyone help.
