Question about 2005 Chevrolet Colorado

2 Answers

REDUCED POWER I have a 2005 colardo and about 2 months ago i was driving and the reduced power came and i it wouldnt let me get above 60mph. So i took it and had it worked on and they said they cleaned the throttle system and what not and it worked fine but today as i started to drive it came back on and i made a stop and turned it off for 10 minutes and when i turned it back on the reduced light was gone. The engine light was still on but other than that its driving fine. What should i do? Is this a problem that needs to be fixed or do i just need to turn it off for a little bit if it does it again to fix it.

    Not to sure what the air flow meter is..but i had this problem happen again real bad this weekend it wont go off now. i can sometimes drive a few miles after starting it before it comes back on and back to 50mph i go. I took it in to the shop again and they said i need to take it to the dealership to have it reprogrammed and rewired. If you think its the air flow meter is there any way i can check that myself or anything else you can offer help wise or do you think i should take it in to the dealership and have all that done?

Had the Reduced Power light on my 2004 Colorado 2 days ago.
It wouldn't rev above 2,000rpm.
It was a Bad battery.. It looks like the Reduced Poewr mode is a Limp Home mode.. if there is a dead cell you'll be able to drive truck w/ enough power from the alternator.
I put the new battery ion and it is running like new

2011 Holden Cruze CDX Petrol, Engine Power Is Reduced message has popped up and I would like to know whey it is happening or what it could be linked to.


Reduced engine power might be caused by a fault that needs investigating with diagnostic equipment but the condition might be linked to delayed routine maintenance and the resetting of the service interval computer when performance might be reduced to protect an unserviced engine.

What causes the "Reduced Engine Power", "Service Stability Control" and "Traction Control" warning lights to come on?


the "Reduced Engine Power", problem causes the PCM to disable "Service Stability Control" and "Traction Control" turning on the warning lights to come on for those systems . The reduced engine power is because of a problem with the electronic throttle control system or as GM calls it TAC system . Reduced Engine Power Mode
When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The PCM will continue to use the accelerator pedal for throttle control, however, the vehicle acceleration is limited.
• Limited throttle mode--The PCM will continue to use the accelerator pedal for throttle control, however, the maximum throttle opening is limited.
• Throttle default mode--The PCM will turn OFF the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The PCM will perform the following actions:
- Limit engine speed to idle by positioning the TP, or by controlling the fuel and spark if the throttle is turned OFF.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The PCM will disable fuel and de-energize the throttle actuator.

GMC Yukon showing Reduced Engine Power, broken oil gauge, running hot


I've had the same problem with the reduced power and tps sensor which is your gas pedal. I replaced it but the problem still existed. I then changed the throttle body and harness to the throttle body but still had the same problem. So I traded the vehicle. I did everything the dealer suggested and I just cut my losses. The Yukon overheating would be a different problem and should be easy to fix.

Reduced Engine Power Error on my 2005 YukonXL


The vehicle is going into a "limp" mode. There is a problem with either engine/transmission that is causing this. The vehicle needs to be scanned for codes to narrow down the problem. Unfortunately at this time, more information is needed to further diagnose. This mode is normal and is a type of default so the vehicle can at least get you off the road and repaired.
