Gentlemen I installed headers on my 2018 and the wiring harness fell onto the header due to relocation to make the O2s hook up. Anyways it BARELY melted through the harness and I see a little Itty bitty baby opening in ONE wire.. It's the pure white wire and the copper is showing through which you can't really see in the pic but if I fold it it opens.. Also those intertwined wires show signs of being burned a little but they are 100% not showing copper so I don't think it's an issue but maybe someone knows?
Could this cause me to throw a P2237 code? The code suggests there's:
Faulty Front Heated Oxygen Sensor Bank 1
Front Heated Oxygen Sensor Bank 1 harness is open or shorted
Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
I had another area up the harness a bit that did burn through the insulation to the copper and I fixed that with butt connectors (this was closer to the ECU) so when I stick the voltmeter into that damaged area seen above, it's reading that I am getting some voltage (by the way I am TERRIBLE with the electrical side so I'm not exactly sure what I need the settings on the voltmeter and what voltage I need) so that tells me the butt connector job I did is working.
ALSO, my A/F ratio is stuck on 9.8 (E85) so to test to see if it was that one wire, before I made any changes, I snipped it in half and fired up the car and NOTHING CHANGED, still same code thrown and so that told me it is indeed that wire that's damaged, or at the very least has something to do with that area. Please help! Thank you in advance!!!
