As modern vehicles continue to grow in complexity, their maintenance needs are changing. Component failures that were commonplace just a decade or two ago are becoming much less common today.
An example of this is the throttle-position sensor, or TPS, which would be mounted on the throttle body, usually on the opposite of the throttle cable. The TPS was used to tell the engine control unit what angle the throttle body was being opened to by the driver, and the ECU would adjust the fuel as needed based on this data as well as other inputs.
These sensors were cheap and easy to replace, they didn’t fail very often, but they would eventually wear out. So, what happened to throttle-position sensors, and why don’t we see them as often today? The short answer is that they’re still around, they’re just incorporated into a larger assembly: the electronic throttle body.
