Limp mode

Hello,

There are several reasons for a car to go into limp mode.
The computer system that controls your car has a built in safety feature called "Reduced Power" or "Limp Mode" which is designed to get the car where it is going under low engine power while protecting the car's engine and transmission. When a malfunction is detected by the computer either from the engine management system or transmission the car should show a Reduced Power and/or the Check Engine Light, some cars will also trigger a Traction Control Light.

What are the trouble codes that you are getting?

Most of the time you can simply turn the engine off then wait for a minute and start it back up. The car will come off of the limp mode if the issue does not exists. Sometimes you will have to disconnect the battery for a minute to get it reset.
Here are some helpful tips for a vehicle in limp mode:
