What is a Throttle Body?
A pretty cool name, right? Definitely sounds like something you’ve heard Vin Diesel yap about in an action movie.
More seriously, your car’s throttle body is part of the network that makes that lovely car of yours scoot around when your right foot steps down on the gas pedal.
So, you’re sitting at a red light, bored out of your mind. Ready for the light to turn green. Mind drifting and pretending that you’re a NASCAR driver. On your marks. Get set. GO! That’s what you expect when the light turns green and you press the pedal to the metal. The throttle body directly impacts that whole sequence. On older cars, the gas pedal is connected to the throttle body which subsequently controls the amount of air and fuel that enters the engine. Most modern cars, on the other hand, have an electronic throttle body that’s controlled by the car’s computer. That impacts whether your car goes faster or slower.
That sounds like wizardry, I know. So, let’s just pretend it is, because I’m guessing you don’t want the more detailed, technical description.
Over time, a throttle body can wear out and need to be replaced if you want to be able to drive your car the way you’re accustomed. This doesn’t happen that often, but it’s not the rarest service, either.
Luckily for you, it’s usually a pretty straightforward service.
Symptoms of a failing Throttle Body
Okay Einstein let’s see how smart you really are. If your throttle body helps control the gas pedal’s efficacy, then what exactly do you think happens when the throttle body has a sick day?
If you guessed “your engine will struggle,” then you’re right.
Without the proper air and fuel being sent to your engine, your car won’t perform the way you want it to. That may mean slower acceleration, jerkiness, or a lot of hesitation.
Massages are cool and all, but your car definitely shouldn’t be giving you one. Unless you have one of those fancy cars with a built-in massage feature.
If your throttle body is failing, the car may shake a bit when it’s idling. Don’t fall for the massage trap! It’s a sign that something is wrong.
If the throttle body is really having issues, then the car may even stall when idling, and that’s not fun. Trust me on that one. You don’t need to find out the hard way.
Check engine warning light is on
Would you look at that? Your car is communicating with you!
I know you don’t really like to pay attention to your check engine warning light since you probably think it’s not very important. Well it is. All the warning lights are. They can save you a lot of hassle, and a huge amount of money. In addition to the check engine light, if your throttle body is failing, you might also see a “reduced power” indicator light illuminate.
Limp home mode
If your throttle body really is having issues, your car might go into “limp home mode.” It will let you know this with - yes, another - indicator light on your dashboard.
Limp home mode is when the car wants to save you from causing further damage, so it limits the speed at which you can drive and tells you to drive on home. And when you get home, don’t try to drive it again until you get it fixed.
How urgent is a Throttle Body replacement?
That depends. Does a car that doesn’t drive well, potentially stalls, and might limit your speed sound fun to you? No? Okay then. Get your throttle body replaced asap.
