Engine light code p1133 on a 2005 chevy colorado

SOURCE: engin light is on

the check engine light can come on for any number of reasons mostly emissions related problems. the first step is to identify the code responsible for the light. there are many auto parts stores that will scan the vehicle free of charge for you. i suggest that first.

SOURCE: I have a 06 chevy colorado engine light came on

hi this could be a lot of things, the only way to find out is to have it checked with a code reader, it could be something simple like a miss fire as sometimes happens or could be something more serious best get it checked out, you could have a sensor gone u/s and you might be using allot of fuel.....hope this helps

If all it was is that you did have it off it will reset by the 3rd drive cycle. It may take between 50 & 200 miles.
