One the the most usual issues owners of the Dodge ram truck often tend to suffer is the etc light flashing out of nowhere. As soon as this happens, it way the electronic throttle control is damaged or malfunctioning – so it is time come repair.
You are watching: How to fix the electronic throttle control 5.7l hemi
But learning how to settle the digital throttle control 5.7L Hemi engine is not straightforward job.
There are assorted reasons the and so on may be failing. And there deserve to be tons of different ways the trouble manifests, for this reason you’ll need to proceed accordingly.
You don’t need to worry, though. We know specifically how to tackle this issue and also solve the (even by yourself).
Below, us talk around this detailed so you deserve to tackle the trouble correctly. So take it a look!

What is an electronic Throttle Control?
To deal with the concerns of digital throttle regulate we very recommend the stunning device for her dodge ram.
Price & Availability
You shouldn’t walk right right into the how-to measures if friend don’t understand what an and so on is and also what that does.
Here, you require to understand that the throttle body is one essential part of most engines nowadays.
If her truck has a 5.7L Hemi, it becomes even more critical as this engine needs maximum control.
The ETC’s whole job is to collect info from the accelerator (sensor in the pedal) and change the throttle accordingly.
When you push the pedal ~ above the truck, the electronic throttle obtain a signal native the sensor. The etc uses this signal together a means to understand how far to open up the throttle.
For example, if you fully press the pedal because that maximum acceleration, then etc will open up the accelerator wide, so more air goes right into the filter and then the engine.
When the waiting reaches the engine, it produces an ext pressure, accelerating, or walking faster.
To make it simpler: an etc job is to know how far you push the pedal so it can let sufficient air inside the engine accordingly.
Symptoms of a poor Electronic Throttle regulate on 5.7L Hemi
By now, you already have a basic idea that what an etc does. Yet how have the right to you understand if that is the digital throttle control of the problem?
Well, there room actually a couple of ways to recognize that. Here are several of them:
Lighted and so on Danger
Your evade RAM has actually an etc light that flashes once it is not functioning well. This is the most precise method to recognize that her truck requirements some checking.
But this flashing may not take place 100% the the time. Or that may at some point occur too late (as the is usual).
So it’s constantly important to understand the other means to inspect this, as we define below.
One that the key ways to recognize whether the etc is malfunctioning is to examine whether you’re getting the same amount of power from pushing the pedal.
If you feeling a slight power reduction every time you push the pedal, yes sir a high opportunity the and so on is malfunctioning.
This happens because the and so on does no calculate the quantity of air come let into the engine well enough.
And in part cases, the occurs due to the fact that the throttle body instantly reduces the lot of air that goes right into the engine when it starts to wear off.
Similarly to a lose in engine power, girlfriend may likewise experience a problem when speeding up the truck. In part cases, you might not even have the ability to get the end of an idle state.
This happens once the throttle system instantly limits the rate of air that goes right into the engine.

Apart from regulating how much air goes right into the engine, the ETC additionally says how much gas goes in.
So as soon as it starts come fail, you will certainly not only experience a loss in acceleration and overall power but likewise in MPG efficiency.
When you sense the vehicle running end the gas tank faster than usual, that’s a sign the and so on is letting too much fuel right into the engine. And also that can be pretty costly if not fixed quickly.
Another factor this may take place is that and so on is not letting girlfriend accelerate too fast.
Sure enough, the engine will still consume a many gas – yet at the same price as if you to be faster. So it will certainly feel as if the van is spend too lot gas.
Another typical symptom of a faulty and so on is when the idling doesn’t execute as usual. This is easy to perceive also as shortly as you turn the engine on.
While the car may not have actually a problem starting, leaving it in idle either avoid working the end of i do not have anything or starts come feel virtually like transforming off by itself.
This symptom is a straightforward way to understand that the etc is shortly to prevent working, together it means the damage is high sufficient to impact the auto performance without even accelerating.
Pedal or Engine Stoppage
When the ETC damage is almost irreversible (most the the time), what you will endure will be clearer and also near best danger.
In this case, you will not only experience acceleration, idling, and also overall power problems – however the pedal may stop working altogether.
And that have the right to be extremely dangerous in many situations.
At the same time, the engine may turn off the end of nowhere. And in part cases, the starts come deaccelerate immediately even if you’re advertise the pedal.
In this case, girlfriend should always fix the electric throttle system prior to it is too late.
What causes a negative Electronic throttle System?
Fixing the etc without having actually an idea of why that is malfunctioning i will not ~ be easy. That’s why friend must always check for any of these usual problems:The throttle body is filled with rustAir filter or vacuum are leakingA sensor or electrical link is looseThere’s severe physical damages on the throttle system
Some the these difficulties can it is in fixed. Yet others can not (so you’ll need to replace the ETC and also possibly other parts as well). One of two people way, listed below you’ll find how to fix accordingly.
How to settle the electronic Throttle manage of a 5.7L hem (DIY Method)
It’s time come truly discover how come fix electronic throttle control, dodge Ram. After ~ learning about the symptoms and also causes, going over the services will be a lot of easier.
But don’t issue if you have actually a different van or engine. You may still discover these advice worth trying. Just remember to follow our advice.
Without much further ado, right here are the various methods you can fix one ETC:
01. Clean the throttle Body
As we stated before, rust is among the most common causes of accelerator bodies malfunctioning. The solution? Clean the rust thoroughly.
