Car went into limp mode in traffic, and then wouldn't start.

- Replaced throttle body (Duralast), car now starts.

Car is now idling high and rough. Still in limp mode. Lightning bolt has remained, oil light joined the party, along with above codes.
- Replaced crankshaft sensor (Duralast)
- Replaced oil pressure sensor (Duralast) *no more oil light only the oil circuit code*
- Replaced app sensor (Napa)

I was told by my local Dodge dealer I would need to do a throttle body relearn. He wanted the same price as the scanner to do it, so I ordered it and it will be here tomorrow.

I have my doubts about the relearn fixing the issue, so I desperately need some guidance on what to do next. Thank you for reading.

 

Update for those that find this post. I did not attempt a relearn (Amazon delivery was late). While waiting for the delivery, I unplugged the oil sensor and attempted to read the codes. To my amazement the lightning bolt was gone. Comes back depending on the connector position. Cutting the connector off, wrapping the wires in electrical tape so it is safe to drive, and then picking up a new harness. Part # 5148105AH

 

Update again: Harness would take a week to arrive. Purchased a Duralast connector and solderless wire connectors / heat shielding. Will post results.

 

Above worked. Back on the road.
