I also have a 2007 chevy cobalt and the check engine light has been on for about a year, so I went through Emissions and the code p2434 showed up---meaning the secondary air injector pump was bad, so now the air pump is replaced and I got it checked on a OBD scanner and it said there was low voltage to the air pump--meaning the old air pump was good and the problem is somewhere else (I checked the old pump with a volt metor)I got the code reset several times and the light still comes on. There is somethlng giving the pump low voltage and I don't know what the solution is. I may be wrong but it may be the connector that goes to the pump but I really don't know.

You need to have it hooked up to a scanner to find out what error the computer has found. (A good garage will do this, and sometimes auto parts stores will do a quick "free" scan)

Why does reduce engine power light comes on chevy


That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.
