I think I put this in the wrong forum page so I'm reposting, sorry about that! I recently purchased my 2011 Silverado and have been putting a bunch of work into it to get it back in shape. Upper control arms, lower ball joints, replaced the drum brakes, wheel cylinders and master cylinder, did a fluid flush for every fluid in the thing, and I replaced a headlight wiring harness that was a bit loose, an oil pressure switch and sway bar links. That being said, I caved and took it to a mechanic because I can’t for the life of me figure out an electrical issue. My driver side lights are all screwed up. Brake light doesn’t turn on but the running lights are working, rear turn signal, front turn signal and the turn signal on the mirror don’t work, the windows washer pump works if I manually power it but not with the switch and I have a “Service Stabilatrak” message and a traction control message. I replaced the tail light circuit board and briefly got my brake light and rear and mirror turn signal back but not the front, but that last about 3 days. So I gave up and took it to a shop and they can’t figure it out either. The best the could recommend was to replace the body control module but they didn’t have the equipment to do it there. Before I bring this to a dealer…. Anybody have any ideas? And could the washer pump issue be related to the lights???

Figured it was a bit suspicious to go from a single oil sensor code to a bunch of random codes haha

I got lucky and went out to dig around and somehow managed to blow the Engine control fuse. Popped a new one in and it’s running like a dream again.

Screen looked good. Only replaced it because I had the new one and figured I may as well while I was already back there

144k and I’ve had the truck for 2 weeks, so I’m not sure about the oil changes. It was within the miles/timeframe from the last oil change it had so I’m hopeful that it was consistent haha

I had a P0523 code on my 2011 Chevy Silverado and replaced the sensor/filter yesterday afternoon. I didn’t take the whole intake manifold off to get to the sensor, just removed a vacuum line to give me a little more room reaching to the rear. After replacing the sensor I went to start my truck to verify the repair worked (my oil pressure had been reading 0) and noticed a real rough idle for a few seconds before the engine stalled. Ran for codes again and now have P0443, P0102, P3401, P3425, P3441 and P3449. I went back through making sure I didn’t disconnect any plugs on accident. What could I have messed up to cause all these error codes to come up at once? And how do I fix it?
