Computer problem
2005 GMC Canyon 6 cyl Four Wheel Drive Automatic 43,000 miles

Can you tell me what P1133 code is when the check engin light comes on and what I need to do to fix it.

Thank you.

P.S. I have an inline 5 cyl engine.

It's your front O2 sensor giving the code. But it may be something else, it's better to have apro look at this as it will save you money in the long run. You could end up changing the sensor and still have a problem and ended up buying a part you didn't need.

I have a 05 Canyon pulling this code as well as a P1201 code. I dont want to take it in and would rather work on it myself but have found nothing on the net on this code that has been very useful. I live in cold climate and was wondering if the fuel lines icing up would pull these codes? Its a manual and I have never worked on one before so. Any suggestions?
