What is  limp mode?

It’s a feature in modern vehicles that’s triggered when the engine or transmission systems detect a major issue.

Reduced Engine Performance

Why is limp mode enabled?

This mode is enabled to ensure that the detected issue doesn’t worsen.

What issues can cause limp mode?

The vehicle’s computer triggers limp mode when it detects abnormal signals from its sensors. These abnormal signals can be caused by a wide range of issues.

Issues such as low oil and coolant levels can trigger limp mode.

Engine issues

Faulty transmission components like shift solenoids and pressure control solenoids can trigger limp mode, as they play a critical part in shifting gears.

Transmission issues

Problems like seized brakes or a hydraulic leak in the brake system can also trigger limp mode.

Faulty brakes

Faulty wiring and sensors

Sensors located throughout the engine and transmission are critical. If they’re faulty, they can affect the vehicle’s performance, efficiency, and reliability.

Limp mode might also mean that your vehicle is low on oil or fluids.

Sometimes, limp mode can be caused by a temporary glitch.  If so, it will deactivate after you restart your vehicle.

What are the effects of limp mode?

Limp mode disables some vehicle systems and significantly lowers engine and transmission performance, allowing the vehicle to limp home.

Your vehicle’s air-conditioning might also shut down.

Your engine will be limited to 2,000 to 3,500 revolutions per minute.

Your vehicle will refuse to accelerate past a certain speed.

These limitations help reduce stress on vehicle components.

If your vehicle’s limp mode is enabled, you should visit a mechanic as soon as possible.

For your safety,  you shouldn’t drive long distances or enter high-speed roads with limp mode enabled.

Driving in limp mode for an extended period of time can further damage your vehicle’s components.
