Fuel Tank Pressure Sensor And Tube, Issue

[Clay]

About two months ago, I had my 2020 Gladiator fuel tank pressure sensor and tube (Mopar 68335037AC) replaced. About ten days ago, my check engine light came on and I went to my local dealership where they determined it was another bad unit, so they ordered a replacement. I dropped off my Gladiator this morning and towards the end of the day, they called and said the pressure sensor wiring harness was corroded and they were ordering a replacement. I have 6,500 miles on my vehicle and it is always parked in my garage, so I have no idea why it would be corroded. The tech thinks there may be a problem with the harnesses, because he had seen where at least 600 of them had been ordered by dealerships around the country. We are planning on getting it installed next Wednesday, so I wonder how long this one will last. Just a heads up in case anyone has to have their pressure switch replaced after getting a check engine light. One other thing, acouple of days after I had taken my vehicle in to have it checked, the check engine light went out.

My Check Engine Light came on, I reset it 2X. Read the code, standard gas cap warning. Took it to dealer, Replaced Fuel Pressure Sensor, around 32K miles.

The build date was 8-20. I have it back, just waiting on the part to arrive at the dealership. They thought it might be two days.

That lets me off the hook if there was a bad batch of wire harnesses. It will give other guys a heads up though.
