SOURCE: why does reduce engine power light comes on chevy

That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.

SOURCE: WHat does it mean when your traction control

Hello Jeremy.
When your traction light comes on it is indicating wheel spin on acceleration. To prevent wheel spin an onboard computer reduces engine power to limit the wheel spin. Some, if not most, cars equipped with this feature will also apply the brakes if wheel spin continues after reducing engine power.
Hope this answers your question.
Thank you for using Fixya!

Possible causes
- Faulty Engine Control Module (ECM)
- ECM harness is open or shorted
- ECM circuit poor electrical connection
- Shorted sensor on 5 volt circuit
help.jpg What does this mean? When is the code detected?
The Engine Control Module (ECM) has detected the sensor 5 volt reference circuit voltage is higher or lower than expected
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0641 Chevrolet Description
The control module has 2 internal 5-volt reference buses called "5-volt reference 1" and"5-volt reference 2". Each reference bus provided 5-volt reference circuit for more than one sensor. Therefore, a fault condition on one 5-volt reference circuit will affect the other 5-volt reference circuits connected to the reference bus. The control module monitors the voltage on the 5-volt reference buses.

Traction conrol


The traction control light is on to let you know that system is disabled. I would say the actual problem is a performance issue with the engine.
You should have someone scan the computer for trouble codes to proceed with testing. A 2010 model may still be under factory warranty.

What is hte proper temp on a 2008 cobalt?


Ususally the thermostat opens at 195 to 200 degrees. Coolant and pressure allow normal temps to go to 230 to 240, and much higher under heat soak condition (unit turned off). Fans kick in near that temp. So, the engine needs to be that hot to be efficient and to have emission controls shift to normal... Also the high temprature prolongs engine life by forcing moisture from the oil.

2003 cobalt traction control light on


traction control is controlled by a button on the dash, the only time the TC light comes on is when its shut off, indicating that you do not have traction control. try locating the button and pushing it and see if that fixes the problem, if not there is something wrong in the tc circuit (such as a wheel speed sensor) and would need further diagnosis.
