I already have the FSM and I've looked at it thoroughly. Not all that helpful always.

I suspect it is something simple like a temperature sensor sending bogus data to the ECM. I had a mechanic from 2carpros.com tell me it likely has an OD solenoid relay somewhere. 2 CARPROS response provided an answered with a picture of where the OD solenoid relay should live, but, I don't find a relay in that spot. The FSM shows an OD relay in the wiring diagram, but that doesn't help with the location of the relay.

So, I'm not a junior at this stuff. I go to the manuals that I already have and of course YouTube and other sourses looking for answers to questions. YouTube is wonderful for some repairs.

If someone could help with the location of the OD relay, I would sure be pleased.

Thanks for your support.
