Red Lightning Bolt Symbol In A Jeep Discussed

The red lightning bolt indicates that there is a problem with the electronic throttle control ETC. However, there can be other problems too but if we consider the most common scenario of it, then it would be ETC. The issues with the throttle control have two different aspects: faulty throttle body and defective electronic throttle. Let’s get enrolled in a debate on this:

What Does Red Lightning Bolt Mean on Jeep?

This is a complicated thing to answer because there can be many reasons behind a red lighting bolt on your jeep’s dashboard but let me explain this more thoroughly. In most cases, the red lightning bolt indicates that there is a problem with the electronic throttle control, shortly called ETC. A damaged or faulty throttle body is the main cause; however, the red lighting bolt can sometimes also be a signal for the defective sensor on the gas pedal of your jeep. Shortly, there is an urgent need to deal with the problem!

Long story short, the red lightning symbol in a jeep means two major problems: defective accelerator pedal position sensor and faulty electronic control throttle. In both cases, you need to take action on an urgent basis as there is no second thought. Otherwise, your jeep will indulge in more complications, so none of us take the vehicle’s health for granted, and for that reason, you need to sort this issue out. Let’s talk about both of these in detail.

What Does Red Lightning Bolt Mean on Jeep

Accelerator Pedal Position Sensor

The red lighting bolt indicates a defective sensor on the gas pedal of your jeep. The accelerator pedal sensor is part of the throttle control system, but I am highlighting it separately because of its integrity. The sensor aims to communicate the information between the accelerator and battery and manipulate the speed of the vehicle. A faulty pedal sensor means you will not get the acceleration or the car will not move at the speed you want because the computer will recognize the wrong information.

Once you have addressed that there is a fault in the sensor, you need to fix it urgently. For that reason, it is suggested to disconnect the negative terminal of the battery in the first place and reconnect it after a few seconds. Now switch on the vehicle to check if the car is performing correctly or not. Don’t worry! I’ll discuss the details above to fix the sensor in the next section because before that you need to have in-depth knowledge of the throttle system.

Electronic Control Throttle

Electronic control throttle aims to accelerate the following features of your jeep: traction control, precrash system, cruise control, and stability control. You see, all these features circulate the management and generation of torque. That’s why it would be right to say that the control throttle follows a certain movement and integrates the above-mentioned features. However, this movement can be irrespective of that of the accelerator of a car.

In the first step, you need to check the battery voltage sensor. In other words, you need to make sure that the sensor is completely fine. For that, disconnect the negative (-) terminal of the battery for a few seconds and then reconnect it. Now turn the jeep on and notice if it is working rightly or not, if not then go on to the next step.

If reconnecting the battery doesn’t fix the sensor issue and the dashboard of your jeep keeps indicating the red light, it means the sensor needs to be replaced as soon as possible. For that purpose, you must visit online or physical stores that sell automotive parts. In my suggestion, do prioritize Amazon retailers because the platform is providing multiple sellers under one roof with detailed specifications and a reviews section for your ease.

If you’ve no faith in your decision or surfing skills, you have an option to ask the vehicle’s customer service for the parts. The brands are also selling the parts of modern cars at good prices along with a warranty. When you go for the same brand, you’re free from the stress of compatibility and stuff like that. Besides that, the cost of the sensor varies along with brands and specifications, so you should address your budget to make a better purchase.

Symptoms Of A Faulty Electronic Throttle Control

As I said before, the faulty electronic control throttle is the common cause behind the red lighting bolt on the dashboard of your jeep but some other symptoms show a problem in ETC. The common symptoms of a defective ETC are as follows: stalling engine, lower cruising speed than usual, reduction in average fuel economy, engine misfiring, rough acceleration, difficulty in speed maintenance, and rough idling. Also, the jeeps which take forever to start could have a fault ETC.

Faulty throttle and bad throttle bodies are two different things. The above symptoms are from the defective electric throttle and the following are the indication of a bad throttle body. The failing body of the electric throttle leads to power shortages, unstable idling, poor mileage, engine light, acceleration issues, electrical complications, and more.

“How to service ETC?” is among the most-asked questions and here is your answer. In the first place, you need to disconnect the battery of your jeep for some minutes as doing this will restart the light and bolt system. However, this trick doesn’t need to work every time, so if it doesn’t, move on to the next. Try to disconnect the electronic throttle body and reconnect it so that the system gets rebooted and turns the light off.

How Do You Fix A Red Lightning Bolt On A Jeep?

A red lightning bolt on a jeep’s dashboard is among the common problems, especially among Gladiators and Wranglers.
