Help! so many codes, so little time.
Check engine light came on. Had codes read.
P1148, p1168, p0037 p0057 p0051 p0031
Basically the pcm detected a open loop. Throwing codes for every o2 sensor. I replaced bank 2 up stream a/f sensor. Cleared the check engine light by unplugging the battery. Had codes read again and same codes. Brought it to the shop. He showed me on his scanner that all my o2 sensors should be up and down zig zag lines and the would work then flat line, work then flat line. And also showed BOTH cam sensors were bad. (No TCS slip light on) 1280 bucks. I asked how they all.go bad at once and he said.they have a life span and can do that. I think he is nuts. I think something caused all them to trip the code. Anyone anyone ever had all sensors just go out? Any info would be great as I am at a complete loss on what to do.
