SOURCE: Service Stabilitrak-Reduced Engine Power

the engine light is a generic fault indicator in your car to point out something is not quite right with the engine, having a loss of power as well is also known in some areas as Limp Mode or Safety Mode. it means the car is restricting the power it gives to ensure no damage it done to the engine.

the only certain way to find out what is wrong is to take it to a garage that has diagnostics equipment that can read the fault codes from the vechicles ECU (the fault codes will be the reason the light on the dash has come on as its reporting a fault somewhere)..

your mechanic should be able to tell you what is wrong with the engine from that and give you a more accurate cost at fixing it.

I would advise to take it to a shop you trust and let them scan your vehicle for trouble codes. From there they can give you an idea as to why these messages appeared. : )

2012 Buick Enclave, dash reads Traction control off, service stabilitrak. Engine power reduced... why????


Engine power reduced... is the main problem ,this turned off Traction control off, service stabilitrak. Your vehicle has electronic throttle control , The Gas pedal has sensors inside which are connected by electrical circuits to the PCM - engine computer ,the PCM use's these inputs to control the throttle plate by use of a 12 volt DC motor . Plus there are position sensors on the throttle body for feed back to the PCM. When one of these signals is off The PCM will put the system into reduced power mode . This will also set DTC'S - diagnostic trouble codes . Your best bet , take it to a qualified repair shop.

Service stabilitrak and reduce engine power on my 2012 chevy equinox and suggestions on what it could be also had a bunch of codes for timing position and I replaced all timing components


The reduced engine power light is most likely setting the stabilitrack light to come on. The reduced engine power light is normally set when the computer senses an issue with the throttle actuator assembly. This actuator assembly needs a corolation signal from the gas pedal sensor to operate properly. In my opinion and experience in the automotive repair industry, the throttle actuator assembly is more prone to failure than the gas pedal sensor.

Since all three systems work together, when the engine light is on the other two can be also.
I would start with checking the engine computer for trouble codes.

{: ) The two triangles you saw is for the StabilTtrak system,, sometimes called the traction control indicator. When you see a spanner beside it, it means the system needs servicing.
StabiliTrak will turn off automatically if a problem is detected in the system. For vehicles without a DIC, the StabiliTrak light and the StabiliTrak service light will both come on. If the StabiliTrak service light does not clear itself after restarting the vehicle, you should see your dealer for service.

These are not codes , they are warning lights , telling you the driver that a problem exist . code says, traction control off,next code says ,service stabilitrak and the last code says...engine power reduced. DTC'S - diagnostic trouble codes could be stored in the control modules that control these system's . The main problem is more then likely with the reduced engine power. This is because of a problem with the electronic throttle control system . This problem will turn off these other thing's , turning on their light's .
Throttle Actuator Control (TAC) System Description
All newer vehicles have this ! There are position sensors in the Gas pedal and on the throttle body on the engine , The computer uses a DC volt electric motor to make the vehicle go . The sensors wear over time , the motor can wear , wiring can break etc...
Reduced Engine Power Mode
When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.
• Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
• Throttle default mode--The ECM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The ECM will perform the following actions:
- Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned off.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator.

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.
