Do you see a lightning bolt warning message illuminated on your Dodge Ram’s dashboard? The message is red or yellow, surrounded by reversed parentheses. If you want to prevent further problems with your Dodge Ram vehicle, you need to know how to fix the lightning bolt warning light.
You will be able to solve this critical error as soon as you read the article I have written to help you fix the lightning bolt issue. As well as exploring what the warning light means, why it appears, and potential causes behind it, we will explore solutions to resolve the issue quickly.
What is the Lightning Bolt Warning Light?
The dashboard of your Dodge Ram truck suddenly displays a warning light symbol that can cause concern when you’re driving it as part of your daily routine. Lightning bolt warning lights indicate the electronic throttle control (ETC) system is malfunctioning and needs to be repaired quickly.
Featuring advanced technology, cutting-edge features, and a luxury interior design, vehicles today like the Dodge Ram facilitate drivers and passengers alike. An advanced feature of the vehicle is the display of alarming issues on the dashboard, which alert drivers to any issues as soon as they occur.
After the blinking warning symbol is activated, it informs Dodge Ram owners of technical as well as mechanical issues.
A properly maintained electronic throttle control system will enhance the performance and longevity of the engine as well as prevent defects, malfunctions, and damage to the components.
Causes of the Lightning Bolt Warning Light
A lightning bolt message can blink on due to a variety of critical causes. We have summarized seven major causes and provided valuable solutions for them. Below is a video that gives you a quick overview of these causes.
- Problems with throttle bodies
- Issues with sensors
- Voltage drop in the battery
- Connection and wiring issues
- Problems with TPMS (tire pressure monitoring system) sensors
- ECU (engine control unit) problems
- Errors in software and vacuum leaks
Problems with Throttle Bodies
A throttle body plays a crucial role in the ETC system because it is part of the air intake system. When an accelerator pedal is pressed, the throttle body opens to allow essential air into the engine to speed up the vehicle. It controls the amount of air entering the engine.
Dirty Throttle Body
As time goes on, dirt, gum, varnish, and carbon deposits accumulate in the throttle body, impairing its function.
Malfunctioning Throttle Body
When your Dodge ram vehicle’s throttle body is faulty or malfunctioning, it can’t regulate airflow into the engine, resulting in an incorrect amount of air entering the engine and causing the lightning bolt warning light to appear.
Issues with Sensor
An accelerator pedal position sensor (APPS) and throttle position sensor (TPS) are part of the throttle body and provide signals that make the throttle body operate efficiently.
Throttle Position Sensor (TPS)
This position is shared with the engine’s ECU by the TPS, which monitors the throttle body. In the event it becomes faulty, it does not have the ability to monitor the throttle body position and begins to send incorrect signals to the ECU as a result.
Accelerator Pedal Position Sensor (APPS)
Similar to APS, APPS transmits the accelerator pedal position to the engine control unit. If your Dodge RAM dashboard is illuminated with a lightning bolt warning light due to a faulty APPS, this will indicate that the accelerator medal isn’t being monitored.
Voltage drop in the battery
It is imperative that the ETC system has an electricity supply in order to work correctly and accelerate the vehicle. Nevertheless, a battery with low voltage, an outdated battery, a damaged battery, or a weak battery can affect engine control unit performance.
Connection and wiring issues
This electronic throttle control system is connected to a large number of wires and components. The ETC and engine control unit can’t communicate properly if any of these connections are loose or damaged.
Problems with TPMS (tire pressure monitoring system) sensors
Each tire on a vehicle has a TPMS, which monitors the air pressure with tiny electric sensors. A yellow warning light appears on the Dodge Ram dashboard when the TPMS sensor detects a change in tire air pressure. The sensors continuously transmit data to the ECU.
It is also possible for TPMS sensors to fail to collect data over time due to dirt or water, which can also lead to the warning of a lightning bolt.
ECU (engine control unit) problems
Monitoring the engine’s health and maintaining its smooth operation is done by the engine control unit. There are multiple internal systems controlled by it, including fuel injection, idle speed control, variable valve timing, and ignition. There are times when the Dodge Ram ECU itself is to blame for flashing a lighting bolt warning light.
The system will function improperly if there are internal problems, such as sensors malfunctioning in the ECU or physical damage to components.
There are several sensors in this system, including camshaft position sensors, temperature sensors in the coolant, wheel speed sensors, knock sensors, and MAP sensors. In the event that any of these sensors is faulty, it can cause the ECU’s overall functions to be compromised.
Errors in software and vacuum leaks
The engine can run lean as a result of vacuum leaks, preventing it from delivering its full potential, and the engine will lose performance as a result.
In addition to software glitches, sensors can send signals to software, which can lead to an error message. Software controls internal system functions, and it receives signals from those sensors. There are a number of serious technical issues that can arise as a result of software glitches in Dodge RAM.
Solutions of lightning bolt warning light
There are a couple of possible solutions that may help you resolve the Dodge Ram lightning bolt warning error.
- Cleaning of throttle body
- Check and replace sensors
- Inspect wires and electric connections
- Update or reprogram the ECU
- Professional diagnosis
Cleaning of throttle body
If you find that the throttle body of your Dodge Ram is dirty, you should spray it with cleaner. Dirt and debris can be removed using an old toothbrush or soft brush after spraying cleaner on the throttle body.
While getting regular maintenance services, including oil changes, tire inspections, injections, system inspections, etc., it is recommended that the throttle body be cleaned as well.
Regardless of how well you clean the throttle body, if it still exhibits any signs of wear, you should replace it.
Check and replace sensors
A malfunctioning or faulty TPS or TPPS sensor can cause the lightning bolts on your Dodge Ram truck dashboard, so you may need to replace them. It is also essential to inspect each TPMS and ECU sensor individually to ensure they are working effectively.
Inspect wires and electric connections
It is important to inspect all wiring connections associated with the ETC system when checking throttle body components. In the event that you find any damaged or corrupted wire, then replace it or repair it and make sure all cables are tightly connected.
Update or Reprogram the ECU
As a result of the complicated structure of the ECU, you may need the assistance of a professional mechanic to update or reset the software.
His team will thoroughly inspect all ECU components and repair or replace any that need to be replaced. Using diagnostic tools, certified technicians can restore software settings and correct bugs and glitches.
Professional Diagnosis
In most cases, your Dodge Ram truck will still flash the lightning bolt light even after you have tried the above solutions. It is recommended that you take your vehicle to your nearest dealership so he can resolve the problem if it happens to you.
Using advanced equipment, expert mechanics can accurately identify the component that needs to be repaired or replaced.
