Stabilitrak doesn't reduce power to the engine. It disengages, no ABS. Reduced power is engine or transmission problems. Have the codes read..Repost

Have a Neff D9610 cooker hood. Has 3 separate speed switches. Slowest speed switch does not work other ok. No noise from motor when slow switch on. Is the problem with the switch or the motor?


When on high speed the motor is running at it's normal speed.

When a slower speed is selected (mostly) there is external circuitry to reduce the current to the motor so it runs at a slower speed, though in some cases the motor could be specially wound for multiple speeds. The latter way is unlikely to be found in a cooker hood or extractor fan or other small appliance.

The fault with your appliance could be the switch or the current reducing circitry. It is only by delving inside and testing that the fault could be found.

I have an 2008 chevy impala as that sometimes give me the message "engine power reduced" "service stabilitrak" WHAT is the problem?


When there is an error with the stability ac system the computer can reduce engine power as a safety precaution. You need to have the stored codes read.

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.

What is stabilitrak chevy


Stabilitrak is a design that lets the ECU and the ABS system share information. If you step on the gas pedal and loose traction, the ABS tells the ECU that you have lost traction. The ECU calculates what it should do to help and usually will ignore your request for "more fuel" (when you step on the gas pedal) and will reduce the power to the transmission until the ABS system communicates that traction has returned. More than likely there is a failure in the ABS system. The problem may be intermittent right now but this will need to be repaired. If you have an ABS code reader please let me know what codes are stored. If not then you will need to send your car in for diagnostis and an estimate for repair, let me know if I can be of any more help, good luck.

2010 chevy 1/2 pick-up 4x4 Check engine light comes on, engine power reduced, and service stabilitrak, traction control off.


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.

2007 chevy avalanche,leaves me stranded or limping home about every 6 months,first code says, traction control off,next code says ,service stabilitrak and the last code says...engine power reduced.its been...


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.

My 2007 gmc yukon denali's stabilitrak continues to come on. What can I do to solve it or to prevent it from coming on?


Stabilitrak uses information from wheel speed sensors. I would have the stabilitrak system codes pulled up to see if any wheel speed sensors are 'locking' up making it seem like you are sliding or locking brakes up, when it is not actually happening. Or, it could be a bad stabilitrak module. Not sure, without seeing if there are any codes in the computer.

Good luck on this repair.

What does service stabletrak mean?


{: ) If you ever see the SERVICE STABILITRAK message, it means there may be a problem with your StabiliTrak® system. If you see this message, try to reset the system by performing the following: stop; turn off the engine; then start the engine again. If the SERVICE STABILITRAK message still comes on, it means there is a problem. You should see your GM dealer for service. The vehicle is safe to drive, however, you do not have the benefit of StabiliTrak®, so reduce your speed and drive accordingly. Press the select button to acknowledge this message and clear it from the DIC display

2006 B4 Subaru Legacy A?C blower motor runs at high speed all the time when switched on


blower motors are regulated by group of resistors that cause the voltage to reduce at different amounts resulting in high to low speeds on the fan. When this fails the motors goes to high speed all the time. These are not expensive or hard to replace. Usually a plug connector and a couple of screws and around $25 will do it. These are located under the dash in the main body of the heater as they rely on air blowing over them to reduce the heat created by the resistance. the side opposite the connector will look like sifferent sizes of wire wound much like a spring to create resistance and slow the blower motor down. Once you have this out you can go to a parts store and ask for a replacement one. good luck

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.
