    Car (Cobalt 2005) went dead suddenly and display panel was dead I could not even open the door initially with the battery operated key.

    After jumping battery on my car, the car started. I have the car engine light on steady. I also noticed later the enhanced traction system light was also on !!

When you have the display panel say engine power reduced...and car stops. The item that needs checking and replacing is called a ECM- Electronic Control Module, it looks like a miniature sealed laptop that plugs in on the drivers side of the engine. We used to have the car do this all the time, until we replaced that module, I have since put 30 K on the car, and it now runs fine. It did cost a few bucks to fix for sure.

Check engine light came on then reduce engine power


When this light comes on it means the computer control module has detected a fault in the system, it has reduced power to avoid any damage to the engine or transmission. You must now have the computer scanned for fault codes, this is done through the diagnostic connector under the dash see photo below.

1998 corvette will not start says reduced power


If the security light is blinking it will not start. The security system needs to be reset. You will have to have a fully charged battery to reset the system. With a full charged battery turn the ignition forward until the warning lights come on and leave the key in the on position for 15min. Turn key off and wait 10sec. then try and start.You may have to perform this procedure a couple of times, however, it is usually successful the first try. The reduced power light can be set by a low voltage/poor charge battery

Engine power reduced displayed


sounds like the camshaft sensor or the crankshaft sensor, either way I think your car is being recalled for a faulty ignition switch which could turn off by itself.

Coolant message,n reduced engine power light is on, wont start


Your battery is too weak to turn the starter. The starter takes much more power than the lights or anything else.

Service Throttle Control


It sounds like these things are all related. When the a computer sees a problem in the Electronic throttle system, it will dissable traction control, and give the reduced engine power alert because the powertrain computer does not know the value of throttle postion.
Codes will need to be scanned in the computersto begin diagnosis.
