Okay so i bought my wife a 99 v6 camaro. I could not pass it up for the price knowing i would have to do some work on it. Changed the camshaft position sensor and i reset the codes. The same code p0341 popped back up ( what could this be about) and so did p0155 bank2 sensor 1, p1401 egr valve stuck open or circuit performance , p1153 h025 insufficient switching bank2 sensor 1. I know i can clean or replace the egr valve. But what are the other codes relating too? Im new to all this since my father no longer works on vehicles for a living. Any advice and help would be appreciated.

 

those are 02 sensor codes. driver side forward sensor. sounds like it is not heating up right.

 

have a close look at the wiring and plugin for the crank sensor. i would recomend you download the manual for your year. go here to download http://www.mediafire.com/?40mfgeoe4ctti yours would be the 99 svcman. i picked up a printed manual on ebabe for both mine.
