I put in a new MAF, got a new filter and reset the battery and I’m still getting the codes above. It’s been a month since I changed everything. I’ve moved on to looking more into a vacuum leak but don’t know where to look. I have a 2017 chevy silverado 1500
I am not surprised replacing the MAF did not solve your problem. The MAF wasn’t bad and the codes don’t identify a bad MAF. You also don’t have a vacuum problem.
All 4 codes are wiring problems. All the sensors in these 4 codes likley share the same harness so start chasing the harnesses back towards the engine computer. I’d guess younwill find a shorted or broken wire or a connector pin that has been pushed out of place. Good Luck, this won’t be easy to find.
