Okay, so my car (2007 Chevy Cobalt LS 2.2 5-speed) has a ton of engine codes.

Now, I replaced some of the parts it said was faulty and am still getting the same error codes. I am honestly at witts end and my inspection runs up on 8-31-12 so I am running out of time to get this thing error free for emmisions.

The codes are:
p0030 - Heated oxygen sensor control circut bank 1 sensor 1 - Confirmed
p0036 - heated oxygen sensor control circut bank 1 sensor 2 - confirmed
p0053 - heated oxygen sensor heater resistance bank 1 sensor 1 - confirmed
p0054 - heated oxygen sensor heater resistance bank 1 sensor 2 - confirmed
p0102 - mass or volume air flow A circut low input - confirmed
p0443 - Evaporative emmisons system purge control valve system - confirmed
p0883 - clutch pedal switch B circut - confirmed

I have replaced the mass air flow sensor and purge control and the same codes came back even after clearing my computers memory by disconnecting the batter for a period of time. I now believe it is electrical and have no ******* clue where to begin. I just bought a hanes manual but have not had the time to sit down and look through it.

I am not mechanically illerate so please do not treat me as a *******. I have put way to much money into this car over the past two months and the stress has my mind fogged. Thus, I am here. Please help me.

 

I would suggest you buy a pcm... And take it to dealer for reflash

 

Or maybe there is a short somewhere... Don't spend money anymore... Take it to someone qualified man.. its too much

 

Start by checking the emission fuse.it feed most of those circuts!

 

O yea I rmember I guy w similar issues last week and replaced it and everything is bac to normal

 

Kept getting tons of codes on my engine. Threw a new on today the P0883, Searched for it and found this, I had these exact codes and bam exact same thing Emissions fuse was blown. Changed it out and now no codes.
