Jeep Wranglers are famous for their tough reliability and recognizable design. Nevertheless, they can have issues like any other car. Jeep Wrangler traction control light and loss of power when accelerating are two prevalent problems with Jeeps.
Transmission fluid may be to blame if your Jeep’s traction control light is flashing and it doesn’t have power. Sometimes, the fluid gets pretty hot. In a Jeep, the traction control light will come on if a sensor detects traction loss.
There is still a possibility that the issue is different from what we think it is, so let’s look at how we find out what’s wrong. Let’s dive in.
Jeep Wrangler Traction Control Light and Loss of Power: Causes and Solution
On slick surfaces, the traction control method eliminates tire slide when accelerating. Therefore, anytime a sensor detects that the SUV is downshifting, the traction control light of the Jeep turns on.
As the system attempts to steady the truck, there can be a power loss. It is one of the basic concepts. But there could be other causes. There could be several reasons for flashing traction control lights and power loss in a Jeep.
Wheels Spinning at a Different Speed
One of the reasons for the traction light blinking is the slower speed of one or more tires. Jeep’s automation system detects the issue when it finds this problem if one or more tires’ speed is less than others.
It can entail spinning off on the ice or turning too quickly. In any case, the traction control mechanism engages as soon as the sensors notice this movement.
The communication between the front and rear axles or shat may be the source of the mismatch in tire speeds. It can be caused by various factors, such as old tires or when the tires are covered in snow or mud.
This issue may occur more frequently when the vehicle is traveling off-road. Therefore, the Jeep Wrangler’s speed sensors monitor all four tires. The Traction Control Light will illuminate when one or more tires move more slowly than the rest.
After that, the automated system becomes unable to manage the traction. Due to the computer’s inability to control the fuel injection into the engine, there is a loss of power.
How to Solve the Issue
To fix this problem, you must check whether your tires are properly inflated. Jeep’s acceleration speed depends on tire force.
You can find the inflation number level in the manual guide to notice if the tires are in the right air or not. When any tire is worn out enough, the issue also can arise.
You should check the tread depth and replace the worn-out tires. If you need to be more skilled, you should leave it to an expert to fix power loss and other issues.
Issues With Throttle System (ETC/ Electric Throttle)
Look out for the Throttle control system whether there is any problem occurring. The throttle valve is controlled by an electric motor (Throttle Actuator Control Motor) and a position sensor for the accelerator pedal.
Additionally, the ETC incorporates a throttle position sensor (TPS). These sensors collect information from the areas of the vehicle where they are located.
Further, this data is sent back to the computer system of the Jeep. The computer then calculates or matches the power the vehicle is charging.
The computer sends the appropriate signal that any component of this circuit malfunctions, regardless of whether the sensor ground circuits were shorted or left open.
A Traction Control Light will illuminate, and power loss will occur when the Jeep’s computer detects a problem with this system.
The computer won’t be able to correctly manage the fuel mixture due to the loss of power. When you step on the gas, you won’t have enough power.
How to Solve the Issue
For five to thirty minutes, unplug the battery. Holding the brake down will allow you to reconnect the battery. The Jeep will be reset.
Inspect the throttle body wiring connector for any damaged wires and restore them with fresh ones if necessary. Rather swap out the throttle body, which will be more secure.
If necessary, identify the defective throttle actuator and replace it.
Check Out ABS System
Turbulence, Vibration, or other problems may cause cracks for a long time use in the circuit board of the ABS module. Most of the time, it is the result of careless driving, such as slamming into bumps at a fast speed.
The ABS module suffers damage, interfering with its ability to interact effectively with other vehicle modules. Because traction won’t function when the ABS isn’t communicating, the traction light will be on.
How to Solve the Issue
A broken ABS module is the underlying cause of these symptoms. It should be replaced or, if possible, fixed by an expert mechanic.
These signs are frequently mistaken as malfunctioning catalytic converters, filthy fuel injectors, or defective spark plugs.
Wheel Speed Sensor Failure
A malfunctioning wheel speed sensor cannot communicate accurate data to the vehicle’s computer. It will lead the computer to believe that one or two tires are whirling and the computer reduces engine power to mitigate this issue.
How to Solve the Issue
The failed sensor should be replaced as the ideal response to this issue. Or you can go to an expert professional to diagnose the fault.
Damaged Brake Pads
Brake pad sensors scrape against brake discs when your Jeep’s brake pads are damaged. Informing you that the brake pads are worn out, the sensor sends a signal to switch on the traction control light.
This signal also reaches the computer system, and a power loss happens to avoid more damage.
The Solution
To get your Jeep back to normal operation, changing the faulty brake pads would be preferable.
What Does It Mean When Your Traction Control Light and Check Engine Light Come On at the Same Time?
The controller, the wheel speed sensors, or the speed sensor for the car aren’t working properly. Check the computer’s stored codes when the engine light becomes turned on to get a head start on figuring out why your traction control isn’t working.
Final Words
Having the traction control light on means something is wrong with the system. A warning light comes on when there’s a problem with the TCM monitor.
As a result, you should have time to slow down and pull over safely to address the problem. There could be a problem with the transmission. The difficulties and solutions above should help you find and fix the issue quickly.
