Question about 2005 Chevrolet Colorado

1 Answer

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 cleaned the battery up. Why is this happening? How do I check error codes on this vehicle?

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.

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.

I think there should be a recall on Chevy Colorado engines, I've done some research and quit a few people has had the same problem....my 05 shuts off or tries to stall when coming to a stop, the engine...


Unfortunatley recalls are only put on vehicles when safety is concerned.

The stalling may be corrected by something as simple as cleaning out the throttle body. Electronic throttles are very sensative and need to be cleaned out every 20k miles.

The "service engine soon" light could be contributing or could be the cause for the stalling. You will need to find out what the code is.

What timing components are going out? Usually timing components dont "start to go out". So please clarify.

Condensation on the dipstick is normal. How is the water in the oil being determined?

Taking your vehicle to the dealer for service will keep you informed of what is going on with your vehicle. They will let you know of maintenance items, problems they have inspected, and potential problems that may occur.

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.

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.
