Question about 2005 Chevrolet Colorado

Reduced Power, Emissions Light is on

My 2005 Colorado sat out in 0 degree weather all day. It started fine at the end of my work day, however, after ideling for a few minutes my engine light came on and a message of Reduced Power. After that, even if I tried to rev it a little, I couldn't get the RPMs up much at all. Did something freeze and will a warmer day or two help?

    Wow, I had the exact same problem! The shop said my Cat converters failed and need to be replaced, that's a $1400 repair! Maybe I'll just junk it. I have an 04 Colorado and its more trouble than its worth.

When weather warms up a bit run engine at 3500rpm and leave it for about 10mins this should clear the cat out,if the cat runs cold it will clog up reducing the power of the engine

Reduced power light came on right after abs fault light came on


Firstly, you will have to perform a jump start, using another vehicle or battery.

I suspect that your alternator may have failed, so please do the following:

1) With vehicle running, use a voltmeter across the battery terminals. If charging is lower than 13.5 volts, then you can replace the alternator.
2) If charging can go up to 14 volts when revving the engine slightly, then go to 3
3) With engine off, check voltage across battery terminals. If lower than 12.4 volts, and if alternator check was okay, then replace the vehicle battery and retry.

Stumbling Idle


possibly ajusting itsself. any severe weather/pressure changes in your area? and if so does your cars cpu compensate for this (thinks its at a different elevation etc then resets its idle proper after a certian time? I have heard of this but not sure if VW uses it) perhaps ask the service tech.

Reduced power code comes up and my truck stalls.


I had the same problem, and the solution was cleaning the throttle body, it does need to be completely removed to be cleaned thoroughly. I just used some brake cleaner on a rag to clean off all the carbon deposits. A friend of mine who is a dealer tech had only seen this trouble code once, and this was the solution. So far, my light has not come back on and the truck is running alot better at idle.

2005 Chevy Colorado - The reduced power mode comes on with the engine light on every so often, it usually clears itself when I shut the vehicle off, sometimes it doesn't. I changed the spark plugs and...


you need to have the codes retrieved and see if you have a code for the throttle module or pedal position sensor, a common problem is the module on the throttle body, which requires throttle body replacement.

Probably a short or loose connection between battery and starter motor, or on either end of cables. Id look there before swapping out starter.On cold days you might put a heater under car for a few hours before using it,do this carefully as to avoid a car fire, or look into a block heater for your engine.

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.
