It will be my goal to explain what it means, the root cause, and how it can be fixed in this article.


What does the Dodge Ram Red Lightning Symbol mean?

In short, the red lightning bolt flashing on your Dodge Ram is an indication that the ETC module has detected a problem.

Several things can cause the light to flash, including a malfunctioning Throttle Body. I’ll discuss a few of these below.


Causes of Dodge Red Lightning Bolt Dash Light

Corroded connectors

This problem can also be caused by dirty connectors. Wires that carry connections between two or more components are called dirty connectors.

Electrical current cannot flow through the wires when dirt and grime get into the connection. It would be impossible for the ETC module to operate properly if this were to happen.

A defective throttle body

There is usually a problem with the throttle body that causes the problem. You can use this part to control how much air goes into your Dodge Ram’s engine. A malfunctioning ETC module will cause your Dodge Ram to detect a fault if your Dodge Ram is not running properly.

A faulty throttle position sensor

A faulty throttle position sensor (TPS) can also lead to this problem, since it sends information to the ETC module about the position of your throttle.

It is known that dirt accumulates on this sensor over time in Ram trucks and I would recommend cleaning it before replacing it.


Symptoms of a bad throttle body on a Dodge Ram

Here are a few other signs that indicate you may be experiencing trouble with your Dodge Ram throttle body now that you know the red lightning light results from a bad throttle body.

Rough Idling

You can also experience rough idling when your Dodge Ram has a bad throttle body. The engine will run roughly when you start up the truck, which is not as smooth as it normally is.

Having it checked out by a mechanic as soon as possible is highly recommended if this happens.

Acceleration power loss

Your Dodge Ram could have a faulty throttle body if you notice that the vehicle isn’t accelerating as quickly as it should.

It might be worth having a professional mechanic check it out if the problem persists.

My recommendation would be to replace the Throttle sensor and body to solve the problem permanently.

A skilled mechanic should be able to do the repair within a few hours based on my personal experience.

It is also recommended that you replace the Throttle Position Sensor (TPS) as well. If your car is idling rough and stalling, you may want to consider installing this part, which is relatively inexpensive and could solve many of your problems.

It is recommended that you go with an auto repair shop with a good reputation if you need to replace your throttle body and sensors.

Having your Dodge dealer do the job for you is the best option if you don’t already have any mechanics in mind.
