What year model is your Durango with 5.9?

Also, for your FYI,

CTM - Central Timer Module - usually controls all your interior functions.

One sensor you did not mention. Crank sensor that is near the crankshaft on the engine. Also, check the main 140 amp fuse. on 99's, the fuse can go bad but still shows good but causes erratic idling behavior. Same for crank sensor.

 

it's a '99... That sensor and fuse is the first I've heard of...I'll check them out tomorrow and report back!

 

I had the O2 sensor replaced...works like a charm. It wasn't even coding a CEL!

 

Glad you got it and thanks for the update!

 

Funny how things come full circle. Your second error came on explaining O2 sensor after replacing the TPS. May have save you alot of grief to just replace a lazy O2 sensor!
