How to Buy a Good Quality Throttle Position Sensor

Does the term throttle position sensor sound all new to you? If so, consider yourself among the many who have never heard of this vehicle part. Clearly it’s part of the throttle, which is what makes your car move, but what exactly is this sensor responsible for?

The throttle position sensor, or the TPS, essentially supervises the actual position of your car's throttle. The information it gathers is then sent to your car’s computer. The TPS is found in the butterfly spindle/shaft. If your vehicle is new, it likely is a non-contact sensor. What happens is as we push down on the gas pedal, that butterfly valve opens up in order to let air flow into the intake manifold.

There are signs to watch for that may indicate your throttle position sensor is failing, or has failed. These signs include:

  • There is no information being sent to your car's computer regarding fuel efficiency and the performance of your engine
  • Your Check Engine light comes on
  • Your car feels as though it is jerking as you accelerate
  • There is a sudden increase in your speed as you are driving
  • Your car idles or stalls suddenly

There are also secondary signs which include poor fuel efficiency and problems when you try to change gears. It should be noted in the newer style of throttle position sensors don’t tend to wear down as fast, since they are non-contact. You don’t even have to pay a premium price for this advantage.

There is no need to purchase the most expensive part out there, as these sensors tend to be pretty consistent across the board. You will however, want to look for a brand new throttle position sensor rather than purchase a used one. A used one could fail at any time. It’s best to get the advice of YourMechanic as far as which one is best suited for your car.

Chrysler 300M - Throttle Position Sensor - Westminster, California
On the first visit he ran a diagnostic , he then explained to me in detail what the codes indicated. We scheduled another appointment, he came out and installed the part two days later and my car runs great, thank you Chriss. We are going to schedule another appointment with Chriss for my Blazer.
Chevrolet Tahoe - Throttle Position Sensor - Huntington Beach, California
Excellent service! Chris took the time to call me prior to my appointment to go over the issue I was having to be sure he was picking up the correct parts. He gave me the option to try are fix the existing part or replace the part, and went through both scenarios with me prior to my appointment. Chris showed up early, and made sure my car was good as new before leaving. I would recommend Chris to all of my family and friends for efficient and honest service. The convenience Your Mechanic provides is worth it in itself, and their prices are also much more competitive than local auto shops.

Ford Taurus - Throttle Position Sensor - Norcross, Georgia
I was very happy with my experience. He was prompt, knowledgeable, and did the job with no problems. However, my check engine light came on again after driving four miles, so I believe there is another problem not related to the service I received. Dan may hear from me again when I find out what's goin g on now. Thanks!
Hyundai Sonata - Throttle Position Sensor - Suwanee, Georgia
Dan was fantastic. He was early, and did a great job. He was extremely professional and knowledgeable. The service was very convenient, and much cheaper than the price I was quoted at local mechanic. I recommend Dan to anyone, you will not be disappointed.
