Got a check engine light 3 weeks ago. Truck would react slowly to accel pedal. Scanner showed P0720 code. Cleared code, truck drove fine for a week, <150 miles. Got light again, truck more symptomatic, got a new sensor, installed it, cleared code. Truck drove fine for two weeks. Now the check engine light on again. Anyone chase the wiring or grounds? "new" sensor could have failed, but would like experience/opinions. 120,000 miles. Stock.

 

Update. Cleared code. Cleaned battery connections and TIPM connection.
My inside/dome lamps would go out after a couple seconds, now they stay on.

 

ran thru a puddle of water and check engine light came on and truck slowed/trans flared. Cleared code. put dielectric grease in socket and reconnected harness. Will confirm fix next time it rains.
