Are you aware that your Dodge Ram’s dashboard displays a red or yellow lightning bolt warning message enclosed in reverse parentheses? In order to prevent further issues with your Dodge Ram vehicle, you need to know how to fix the lightning bolt warning light.
My article will help you resolve the lightning bolt issue, and once you read it, you will be able to resolve the issue quickly. Moreover, we will examine the meaning and reasons behind this warning light, as well as potential causes and potential solutions to resolve this issue as soon as possible.
What is the Lightning Bolt Warning Light?
Suddenly, the dashboard of your Dodge Ram truck displays a warning light symbol, which can cause concern when driving every day. Lightning bolt warning lights indicate a problem with the electronic throttle control system (ETC) that needs to be addressed right away.
With advanced features, cutting-edge technology, and a luxurious interior design, vehicles like the Dodge Ram provide a comfortable and convenient ride for the driver and the passengers. An advanced feature of this car is the dashboard alarm which alerts drivers to problems right away.
Dodge Ram owners are informed with a blinking warning symbol when they are experiencing technical or mechanical issues.
In addition to maintaining and preventing defects, malfunctions, and damage to electronic throttle control components, you should also maintain the engine’s performance and longevity.
Lightning Bolt Warning Light Causes
There are several critical causes for the lightning bolt message to blink on. Below you will find a breakdown of seven major causes and their beneficial solutions. You can also watch the video below to get a quick overview of these causes.
Throttle Body Issues
The ETC system relies heavily on the throttle body as part of its air intake system. Throttle bodies control how much air enters the engine, so that when the driver presses the accelerator pedal, essential air enters the engine that assists in acceleration.
Dirty Throttle Body
There can be a buildup of dirt, gum, varnish, and carbon deposits on the throttle body over time, which can impede its proper functioning.
Malfunctioning Throttle Body
The throttle body cannot function properly when it becomes faulty or malfunctioning, so it starts entering incorrect amounts of air which can cause your Dodge ram vehicle to display a lightning bolt warning light.
Sensor Issues
TPS and APPS sensors provide signals allowing the throttle body to operate efficiently. TPS is located on the throttle body and APPS is located on the accelerator pedal.
Throttle Position Sensor (TPS)
The TPS is responsible for monitoring the position of the throttle body and informing the engine’s ECU about it. The throttle body cannot be monitored when it becomes faulty and incorrect signals are sent to the engine controller.
Accelerator Pedal Position Sensor (APPS)
A similar function to APS is the transmission of accelerator pedal position to the ECU through APPS. Dodge RAM dashboards can display a lightning bolt warning light when the accelerator pedal position is not monitored by the APPS.
Low Battery Voltage
The ETC system operates correctly and accelerates the vehicle only with power supply. The engine control unit (ECU) can still be affected by a low voltage, an old, damaged, and weak battery.
Wiring And Connection Problems
Electronic throttle control systems are composed of many wires and components. It is possible for the ETC and the engine control unit to lose communication when any of these connections become loose or damaged.
Tyre pressure monitoring system sensor (TPMS) issues
The TPMS monitors the air pressure of each tire on a vehicle by utilizing small electric sensors. Dodge Ram’s dashboard displays a yellow color warning light when TPMS sensors detect a change in the tires’ air pressure. It transfers data to the ECU continuously.
It’s not uncommon for TPMS sensors to become faulty over time due to dirt or water, which can also cause lightning bolt warnings.
Engine control unit (ECU) issues
Monitoring and maintaining engine health is the responsibility of the engine control unit. It controls several internal components such as fuel injection systems, idle speed control systems, variable valve timing systems, and ignition systems. Occasionally, Dodge Ram lighting bolt warning lights flash due to the ECU itself.
A malfunctioning sensor in the ECU, physical damage, or signs of wear and tear on components will cause the system to malfunction.
This sensor train includes camshaft position sensors, coolant temperature sensors, wheel speed sensors, knock sensors, and MAP sensors, etc. It is possible for the overall functionality of the ECU to be affected by any of these faulty sensors.
Vacuum leaks and software glitches
When the engine runs lean due to vacuum leaks, it won’t perform to its full potential, and it will lose its performance.
In addition to controlling internal system functions and receiving signals from sensors, software glitches can also trigger the error message. Dodge RAM may experience serious technical issues due to a glitch in its software.
Lightning bolt warning light Solutions
Dodge Ram truck owners may find these solutions helpful in eliminating the lightning bolt warning error.
Cleaning of throttle body
If you discover that the throttle body on your Dodge Ram is dirty, you should use a cleaner spray to clean it. Use an old toothbrush or soft brush to remove dirt and debris from the throttle body after spraying cleaner on it.
While getting regular maintenance such as oil changes, tire inspections, injections, system checks, and so on, it is recommended that the throttle body be cleaned. Even if you have perfectly cleaned the throttle body, it would be better to replace it if it still shows signs of wear.
Check and replace sensors
TPPS or TPS sensors that malfunction or show faults may need to be replaced in your Dodge Ram truck dashboard to fix the lightning bolt problem. To ensure TPMS and ECU sensors are functioning correctly, they must also be inspected one by one.
Inspect wires and electric connections
Make sure all wiring connections associated with the ETC system are checked when checking throttle body components. The loose connections on all cables must be repaired or replaced if they are damaged or corrupted.
Update or Reprogram the ECU
In the event that updating or resetting the software and detecting faults in the ECU is difficult for you, you may need to seek the assistance of a mechanic.
A thorough inspection of all ECU components will be conducted. If necessary, any component will be repaired or replaced. Using diagnostic tools, certified technicians can reset software and remove bugs and glitches.
Professional Diagnosis
Usually, the lightning bolt light in your Dodge Ram truck will stop flashing after you’ve tried the above solutions. However, if it happens to you, I would recommend that you bring your vehicle to your nearest dealership and seek his help.
Through the use of advanced equipment, mechanics will determine which component needs to be repaired or replaced.
Conclusion
Finally, the bright lightning bolt warning light on a Dodge Ram indicates to the driver that a problem could exist with the electronic throttle control system and that they should address it quickly in order to clear the error warning from the dashboard as soon as possible.
In most cases, you can solve your problem without going to the mechanic by following the above causes and implementing the appropriate solutions. It is recommended that you only handle solutions yourself if you have a thorough understanding of ECU components and the electronic throttle control system.
