My rear end just got tight thinking about this. But it sounds like a solid plan. Im getting one more sensor to solve and then if it doesn't will proceed. Thank you for helping me game plan next steps.
This may or may not work. If the harness is moved around and not in it's normal resting position, the short may not show itself. You need to physically inspect the harness for bare or chafed wires.Another test from my friend. Disconnect harness and connector. One side Voltmeter connected to oss connector sensor pin (not ground). Other side voltmeter connected to negative battery post. Should be infinite resistance if not you have a short to ground (the frame) on that wire.
Understand we did try and do that as well. Feel around and move the harness while doing test as well. The code comes back within 3-15 miles so I feel like if its the wiring it's sitting like that all the time. New sensor just arrived. Installed about to testThis may or may not work. If the harness is moved around and not in it's normal resting position, the short may not show itself. You need to physically inspect the harness for bare or chafed wires.
Just my opinion.
rlenglish thia is great info did you have to take the cat off to get to the plug on that passenger side. I was in some deep water for 15 seconds tops. I was trying to get to the tranny sensors on the passenger side and I dont see how to get them out without taking the cat out?Back when these were still fairly new they would trigger solenoid codes. Sometimes it was internal but a lot of times it was water intrusion into the main transmission plug on the top passenger side of the transmission. I think it is a 10 way connector and you used to be able to order a new one if it was corroded. You did say that you were in water.
If memory serves me correct they were a PITA to deal with.
