What is Limp Mode and How To Fix It?

Have you ever driven a car on a rugged patch and suddenly had it slow down or stuck in the lowest gear? In that situation, cursing is just not going to help because this might be an indication of a fault in the system of your automobile.

The system of transmission in your vehicle is controlled by an Electronic Control Unit that is also responsible for regulating the engine. A failure in the appropriate functioning of this unit might be because of a condition called the Limp Mode.

Limp Mode

What is Limp Mode?

The engine is governed by certain factors like:

– Integrated circuit which provides information about any malfunctioning.

-Manifold absolute pressure, Throttle pressure and Exhaust Gas Temperature which gives you the pressure information during an uphill motion.

When the Turbo Direct Injection of your automobile suffers a sudden loss of power while driving uphill, it is known as the limp mode. The power is restored once you restart.

Sometimes we mistakenly regard an engine breakdown or complete malfunctioning of an automobile to be a consequence of its Transmission Fail Safe Mode or limp mode. If your engine suffers a sudden breakdown on a level road, you will have two situations to consider:

  1. If the engine shuts down properly after a second, then the possible reasons are:
  • Fault in the air admission pipe
  • Inefficient fuel filter
  1. Otherwise, the immobilizer in your car needs a check.

What Causes the Limp Mode?

Just like all programs have bugs or computers can crash, the transmission of your automobile can malfunction. Let us list why your vehicle may go into limp mode:

 -Issues in Transmission

The ECU detects and informs you immediately about any interruption or breakdown affecting the transmission.

-Boost Deviation

Any problem in the boost deviation of the car gets illustrated by the programmed codes.

-Wiring and Leakage

The Limp mode can also occur due to any wear and tear in the wiring inside the car’s system as well as due to any leakage in the battery.

What Should You Do?

Stressing over this unforeseen damage in your automobile won’t help. The limp mode is nothing to worry about. The good news is that your transmission will not suffer any further harm because the limp mode protects your vehicle, but it will need immediate attention of a service center.

The modern cars come with specific ‘check-engine’ signals that tip you off about the limp mode conditions. They have lesser wiring which lowers the chances of damage. However, proficient diagnosis is needed in this case too. Since driving with a slow speed of 35-40 mph is not recommended at all, park your car safe and get it towed to a nearby service garage whenever you face this situation.

So, do a thorough check on the nature of your transmission regularly and save the extra repair bills! Your automobile deserves the best care you can provide it with.
