How To Service Electronic Throttle Control 6.7 Cummins

Back in the twenty-four hours, your vehicle's throttle body had a wire that connected to the pedal. When you pushed the pedal, you opened the throttle body, and you lot increased the amount of air that enters your engine. Merely in equally technologies advanced, physical linkages were replaced with sensors and actuators.

While this organization allows for better air to fuel ratios for better fuel economy and engine performance, the tradeoff is that if a sensor or actuator breaks, yous lose command of your throttle. That's why vehicle manufacturers packed their vehicles full of sensors and an entire system to monitor your electronic throttle control.

Just what does information technology mean when your throttle command lite comes on, and what should you do? More importantly, is it safe to drive your vehicle, or do yous need to take it straight to a repair store? We'll reply all those questions and more here.

What Does The Electronic Throttle Control Light Mean?

The electronic throttle command light indicates that there is an issue with the throttle arrangement. The throttle system includes the throttle body, accelerator pedal, and wirings. The electronic throttle control organisation command and monitors the position of the throttle.

While older vehicles use a cable that's linked directly to the throttle body, most modern cars achieve this feat through sensors and your vehicle's ECM.

While there are plenty of advantages to this, if everything isn't working the manner it should, then you're not going to accelerate the way yous should.

Electronic Throttle Control Light Function

Your electronic throttle control light monitors the throttle control arrangement to ensure that everything is working the way it should. When it's non, the low-cal turns on to let you know that at that place is a problem.

The only other time you should run across the electronic throttle control light is when yous turn on your vehicle. At this point, your vehicle is completing a system cheque, and when everything checks out, the light should turn off. All the same, if the calorie-free stays on, you have an underlying problem that you lot need to address.

The easiest fashion to narrow downward where you need to look is to claw upwardly an OBD-Ii reader. While these tools can't tell you with 100 percent certainty what the problem is, they can give y'all a proficient place to offset your search.

What Causes An Electronic Throttle Control Light To Come On?

The most common causes of an electronic throttle control light are a faulty throttle command sensor or a faulty throttle accelerator pedal position sensor. But while those are the most common causes of an electronic throttle light, they aren't the only things that could exist going on.

Nosotros've taken a deep dive into the iii most common problems below.

i. Faulty Throttle Control Sensor

Just because your vehicle's ECM tells the throttle to open a specific amount doesn't mean that the ECM trusts that information technology volition. It really relies on the throttle command sensor to tell it how far the throttle has actually opened and makes fuel-to-air ratio adjustments based on that.

Equally every good mechanic knows, you need to trust but verify. This is exactly what your ECM is doing by listening to the throttle control sensor. So, when everything doesn't come up back the way it expects, it throws an electronic throttle control calorie-free so you can check out what's going on.

In some throttle bodies, the sensor is not replaceable and you may take to replace the whole throttle torso, which can be quite plush.

2. Faulty Accelerator Pedal Position Sensor

There are a few different parts to your electronic throttle control organisation, and an integral one is the accelerator pedal position sensor. This sensor communicates with your vehicle's ECM to permit information technology know how fast you want to go.

From there, the ECM tells the throttle how much to open up or close. But if the ECM can't get an accurate reading from the pedal due to a faulty sensor, you'll never get the dispatch y'all want. If the computer recognizes that something is incorrect with the sensor, you'll go an electronic throttle control light.

3. Stuck Throttle Body

It doesn't affair if everything on the electrical side of the house is working correctly if the physical throttle body is stuck. At that place are plenty of reasons that the throttle body tin go stuck, just a mutual one is carbon build-up.

Have a look at your throttle body and ensure that information technology can easily open and shut. If information technology can't, see if you can't remove whatsoever obstructions and try cleaning it with a high-quality carb cleaner. If that withal doesn't work, y'all might need to replace the throttle body.

Is Information technology Safe To Bulldoze With an Electronic Throttle Control Lite?

It is non condom to drive with an electronic throttle control light. While you lot might be lucky and only have a drop in fuel efficiency or a slight drop in acceleration, the trouble can quickly go worse if the sensor readings go on to go amiss.

The throttle body controls how much air enters the engine, and if your vehicle's ECM tin can't keep accurate tabs on this, and then it tin can quickly pb to an out-of-control engine. If you have an electronic throttle light that's on, you lot tin can quickly damage your engine, which tin can pb to even more than expensive repairs when y'all get information technology to a repair store.

This is true fifty-fifty if you lot don't find significant drops in your throttle response or vehicle operation. That'south because the air to fuel ratio isn't what it should be, which tin lead to premature engine article of clothing over fourth dimension.

FAQs

How much does it cost to fix the ETC light?

The cost to prepare the ETC lite will depend on the underlying cause of the calorie-free coming on. If information technology is a elementary upshot, like merely a dirty throttle body, and so it may but price a few dollars to fix. However, if there is a more than serious problem, like a bad throttle trunk or throttle torso sensor, it could cost betwixt $100 and $800 to repair.

Is there a fuse for the electronic throttle control?

In that location isn't a fuse specifically for the electronic throttle command in the majority of most modern cars, but there is a fuse for the engine control module. The engine command module is what controls the electronic throttle control, then if that fuse blows, then the electronic throttle control will no longer work.

How do I reset my ETC light?

To reset the ETC lite, you must use an OBD2 scanner. However, in most cases you cannot simply reset the ETC calorie-free by clearing the fault lawmaking retention. You lot probably demand to fix the problem that caused the warning light in the first identify.

Why is my ETC lite blinking?

If your Electronic throttle control alarm light is blinking, it indicates that there is an ongoing consequence that needs immediate attending. Have your vehicle to a mechanic workshop or diagnose it yourself every bit soon as possible.

Decision: Throttle Control Light

When the throttle control lite comes on, information technology indicates a problem with the throttle control system. The throttle control system includes the accelerator pedal, throttle torso, and all the parts in between.

While you might experience that everything is getting more than complicated in modernistic vehicles, these complicated features have huge benefits. Not simply do you lot go improve fuel economy, but you become a more powerful and more responsive engine.

The most common causes of a throttle control low-cal include:

• Faulty Throttle Control Sensor
• Faulty Accelerator Pedal Position Sensor
• Stuck Throttle Body
• Faulty Throttle Body
• Wiring Bug

When your throttle control light comes on, the kickoff matter y'all desire to practice is read the trouble codes with a diagnostic scanner. In almost cases, the scanner will tell y'all exactly what is causing the warning light to come on.

So, while you might be cursing the electronic throttle control light now when yous get everything dorsum to working every bit information technology should, you lot'll exist glad you have information technology. And despite what the crusty mechanic at the shop might tell you, the old linkage systems used to human action upward from time to time also.
