Take a close look at your thermistors near the firewall and the wiring in connector pins to your thermistors. The most common cause of this is either an open circuit in the wiring to your thermistors or faulty thermistors over near your dryer close to the firewall on the passenger side. Check for broken or corroded wires in the wiring a connector pins and if okay replace your thermistors and check for damaged pigtails to them as well.

If the thermistors are new there is a common problem with the wiring and pigtails for the thermistors as well so check for that thoroughly. Also check your relays in the circuit as well as your fuses.

Connector 4004 bus 1602 pin number 7 which is your Inlet thermistor circuit saying there is an open circuit in that circuit. Test your thermistor wires and inspect them thoroughly for any damage or corroded pins Etc.

connectors were replaced, wiring looked good a far back as traced. Fuses all checked out okay. do you know which relay I would be looking at in the engine compartment fuse box? None seem to be labeled specifically. I'm leaning to a glitch in the body controller.

Be sure that you didn't just visually inspect your wiring because a visual inspection will show the obvious if there is damage however it will not tell you if corrosion or any of the connectors or not making contact that you can't see and it will not tell you if a ground is not making good contact. It will also not tell you if the proper voltage is going through the circuit as well so you will need to test the circuit with a voltmeter and ohmmeter for continuity and grounds
