My Car is Not Accelerating – What Does This Mean?

Picture it: you’re sitting at a light and it turns green. You put your foot on the accelerator and the car barely begins to move. You push the pedal all the way to the floor and still, the car won’t accelerate. People behind you are laying on their horns, you get frazzled, and you’re going to be late to work. You’ve got car accelerator problems.

What could cause problems in acceleration? Problems like these have become increasingly common in cars that have high mileage and are very fuel efficient. Fixing the problems is a simple trip—or tow—to your dealership.

The first problem, and most of the problems, have to do with air flow and the oxygen sensors that are in your car. If the air flow meter becomes clogged, the computer system that measures the air/fuel mixture will in turn malfunction. When this malfunctions, the car will refuse to accelerate. At the same time, an oxygen sensor that malfunctions will lead to the same problem.

Another part that has been continually updated and has slowly become technologically advanced is the throttle position sensor, or TPS. This piece measures the angle of the speed pedal to the floor: the smaller the angle, the quicker the TPS alerts the engine’s computer to accelerate. When this malfunctions, it sends signals that you do not want the car to accelerate that quickly, or at all!

A third problem is an issue that is shared across many automobile types: clogged air filters. A clogged air filter can be an issue that limits the amount of air entering the engine, leading to further malfunctions with the air flow sensor—see above—and not allowing the car to accelerate.

Yet, of all the car accelerator problems that could result in your vehicle not accelerating as it should, the most common is a clutch problem. Clutches not properly engaging the gearbox is a common mechanical error that occurs in vehicles both old and new. When the clutch doesn’t engage the gearbox properly, it results in what is called a “slipping clutch,” in which the car doesn’t properly switch between gears. This problem can be dangerous, and you should take your car into a mechanic to have it fixed if you think that is the problem!

Finally, the issue may be the timing belt, which is, quite literally, one of the most important parts of your engine. Moreover, it is one of the easiest to check, but for some reason it gets overlooked except when taken in to a mechanic. One slip up on these can cause car accelerator problems, so check the belt often!
