When the vehicle on-board computer (ECM) detects a system error, it will go into reduced power mode, also called limp mode.
The most common fix is the throttle body needs to be cleaned, but other issues can also cause the problem.
It is best to use an OBDII scan tool and scan for codes to get a detailed report on the engine.
Why Does it Say Engine Power is Reduced?
Many modern cars have a system that will allow the vehicle to drive a short while instead of completely breaking down.
This system is called Limp Mode, and with a Chevrolet, it will display a message that says “Engine Power Reduced.”
When Limp Mode happens to a Chevy Equinox, it is necessary to find a safe place to pull over or get home until the vehicle can be checked out.
Basically, a malfunction has happened, and the vehicle has gone into Limp Mode so you can find a safe place to pull over or, if close, get home.

The error codes will show the problems the vehicle is having.
For example, an OBDII code P0090 is a Fuel pressure regulated control circuit.
In this example, it would point to a fuel pressure problem as the limp mode cause.
Once the code is known, the problem can be looked at more in-depth.
There are many OBDII scan tools available, from low-cost to high-end units.
The most commonly reported fix is the throttle body needs cleaning but it can be caused by other malfunctions.

Can I Drive with an Engine Power is Reduced Message?
The Chevy will have reduced power, so while it is possible it can be driven, the speed will be greatly reduced.
Sometimes if the vehicle sits awhile, it may regain power temporarily but will likely go back into reduced power mode.
Even if the vehicle becomes drive-able, it is best to get it home or to a shop to be looked at and not do any more driving as the problem will likely return.
The reduced power limp mode was designed to help get a car to a shop or home and not to be driven any farther.
Is an Engine Power Reduced Expensive to Fix?
The repair cost will depend on the problem that caused the reduced power issue.
If the problem is the common throttle body cleaning, it will cost roughly $200-$300.
This is, of course, a guess as to cost, with the only way to know for sure is to call around and get quotes.
If you have an OBDII scan tool, the codes will show if the problem is something else.
