Question
30threeDegree
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?
