So I was driving the other day my engine light came on for a few days and then it went away for a few days. It did this for a few weeks so I didnt know what was going on till the engine light stay on for permanently so I took it to get an enginelight test and this codes came on p0172, p0455, and p0496. Will someone please tell me whats wrong and how can I fix it please ?

Advance Auto has a code reader, for free. I had a bothersome code on/off a few months back, took it to Advance, told me it was a cam sensor. I had to get it from the Chevy dealership, under $100 bucks, about 10 minutes to replace, code hasn't come back.

I just did a search on your code, go to ecotecforum.com and it has your answer and what to do to fix/test.
