Question about 2007 Chevrolet Tahoe

Open Question

2007 Chevy Tahoe. Stabilitrack Service message w/ engine light always on. Reduced Power warning and car slows -- has been going on for a month -- I reset it and turn car off and goes for a week and happens again. Was on freeway going 75 and came on last night and engine power reduced etc... I had put a DYNOVALVE on car 6 months ago -- (dynovalve.com) electronically controlled PCV valve... Could this be the problem or does the Stabilitrack go out in the 2007's about now and if so about how much to service ?

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.

Reduced power and service stabilitrack on my 2007 equinox.


The reduced power light is most likely responsible for the stabilitrack light to illuminate as it will shut it down as a safety feature. The reduced engine power light is normally set by a defective throttle control motor. In some cases, the sensor on the gas pedal can also cause this message to display, but, in my experience, the throttle control motor is most likely the problem.

The engine noise is not related to the stabilitrack. Stabilitrack is usually caused by a bad wheel sensor. Get the trouble codes read to find out exactly what's going on. Which engine do you have?

The check engine light keeps coming on in my 2004 Chevy Tahoe. At first when it came on, it would show a warning message that states Reduced Engine Speed and the Tahoe wouldn't have any power. Now, it's...


Most auto parts stores have Scanners that can read the actual Codes causing the check engine light- usually for FREE. Google the Codes to determine what needs fixed.

Do not continue to drive it, as it may cause permanent damage!

the post that everybody refuse to read or acknowledge is the first simple instruction
when ever there is a problem , have the fault codes read first
it is free at autozone and other parts shops
then knowing what the problem is you can have it fixed at an accredited service center for less money that fixing what is not faulty costs
