Hi,
I bought my mustang last october, after some weeks it throw a code, which was the cam position sensor, i replaced it and everything came ok..

Now i have other issues, my car started to throw the codes:
P0135
P0141
P0155
P0161
P0443
I have been googling and found that the codes are for the O2 sensors on the exhaust and the canister....
at the same time the A/C started to fail, it Works for 1 or 2 minutes and stops the fresh air....
I dont know if the A/C fail is because the other codes or not but I need some help to start checking my car, i already took a look on the fuses, both modules, all of them are ok.....
the car has Borla exhaust (axle), airaid intake and this is it.....
any advice where to start???

Thanks...

I know this is a very old post, I have the same codes! Did you ever find the issue?

hey, did you find a fix for this? what are the steps you followed for the same?

I went to see an engine tuner two years ago, he told me the power commander I had on my car might have been the problem. The previous owner had installed it.
He charged me 300$ and told me the problem would disappear, I was skeptical! He plugged my 2006 get into a computer and told me to try it. The car performances like new. The power was all there. I asked what he did. He said he emptied the old tune and reinstalled the tune from Ford , and adjusted it. He said someone might have played with the catalytic converters. That I don’t think so.
So it’s been two years, no check engines. Full power. My option go see a reputable tuner and ask his opinion.

Okay I shall look into it, although I have returned the car to its stock tune currently which should technically do what your tuner did, I have to retune it now to see if it does anything. But I will research on this and get into more detail.

My stick tune was no longer in the power commander, or it was corrupted. I would definitely go see a pro for this one.
Good luck!

I have a SCT tuner which in theory has the stock tune, so it should work I guess, if not I'll go see a professional tuner. Also is the power commander the same as ECU or are they two different things?

Bigxgun

Actually mine was a SCT too.
He told me it was because it was badly installed that it messed up and the original tune was gone. He told me if I want to use it again I had to send it back to the company to clear it. I’m just glad now the car has been working perfectly the last two years.

Okay I'll look into it with immediate effect.
