This is caused by a fault with the TAC (Throttle Acuator Control) system of your vehicle. You will have to test the TAC, ecu, and the electronic throttle actuator to find source of problem. Will have to take to dealership for these tests.

Why did the reduced engine power and service traction light come on. The car can be started then looses power and stalls out.


When the check engine light comes on it disables other module features as a safety issue. The reduced engine power light is normally caused by a defective throttle actuator motor assembly. In some instances, it can also be caused by a defective gas pedal sensor as well. In my experience, the throttle actuator motor is the most common repair

Why does my 2005 gmc z71 gauges jump around reduced engine power doors unlock and lock and engine stalls but starts immediately when I stop and put in park after I hit a bump


As far as your gages and door locks, Any component that gets feed from ignition switch, I'd have to check feed to and from ignition switch when the problem is ongoing. I haven't looked at your wiring diagram, yet. Also, you may be able to check voltage at applicable fuse circuit, when problem is ongoing.

How do I wire a fuel gauge on 1940 Pontiac Silver Streak?


You would need to use a reducer between the gauge and the power source. A reducer would drop the voltage from 12 back down to 6.

WHAT COULD BE THE PROBLEM WITH MY 2000 GMC YOKON XL WHEN A REDUCED ENGINE POWER MESSAGE COMES ON THE MESSAGE CENTER


A sensor within the car's computer system has detected a possibly major problem. The system then puts the engine into "limp mode" so that it can be driven to a repair station. Driving in this condition will only increase the damage. Highly recommend you take to reputable mechanic immediately for computer diagnostic.

I have a toyota rav 4 1996 & the engine warning light has just started to come on & the car loses power as soon as the light goes on & then the light will just go off & the car runs normal...


Does it loose power all together as if the engine shuts down or does it go itnto a reduced power state?

Check all of your fluid levels. Keep an eye on all of your other gauges when this happens. Some vehicles will automatically go to a reduced power state to protect itself from damage if overheating etc.

More likely, another simple problem could be a loose connection somewhere. Start by checking your battery terminals, and any connections under the hood that can vibrate loose. Typicallly if a problem just "goes away" suddenly. It is an electrical problem.

No gauges


Yes, there is a voltage regulator for the insturments -- it's usually on the back of the instrument panel -- will have to be removed to access.
