Topfactory TH157 Throttle Position Sensor: Compatible with Ford F-150
Available Options
You'd think something called a 'throttle position sensor' would be a minor footnote in an engine's symphony. In reality, it's the conductor. This little gizmo keeps a constant eye on the throttle valve's every move, feeding a live data stream straight to the engine's brain—the ECU. Get that data right, and you've got buttery-smooth acceleration, miserly fuel sipping, and cleaner exhaust. Miss the mark, and well, things get grumpy.
This particular unit is no generic part. It's precision-tooled for a specific era of American workhorse: the Ford F-150, from '97 to '03, with the 4.2L, 4.6L, or 5.4L engines. In those trucks, it's not just a sensor; it's a guardian of grunt.
When this sensor goes on the fritz, the symptoms aren't subtle. Think rough idling that feels like a bad caffeine tremor, acceleration that hesitates like a bad first date, or the ultimate party foul—a full stall. Swapping in a fresh one is often the cure. For anyone who's ever wielded a wrench, it's a straightforward job: kill the battery's juice, find the sensor mounted on the throttle body, and swap it out. Basic tools, minimal fuss.
It's a small part with a big job. Keep it healthy, and your engine repays you with longevity and a few extra miles per gallon. Neglect it, and you're just one faulty signal away from a very expensive bad day.

Throttle Position Sensor

As someone who's been around engines and loves tinkering with my truck, I was cautiously enthusiastic about this part. I installed it a couple of months ago, and it's made a noticeable difference—no more hesitation during acceleration, which is a huge relief. But honestly, for the cost, I expected a bit more durability or maybe some extra features. It's a solid fix, but not perfect. If you're dealing with similar issues, this could be your go-to, but keep an eye on it :)
- Pros: This sensor is a game changer for keeping my truck's engine running smoothly, with acceleration that feels buttery and fuel efficiency that's miserly. It was straightforward to install with basic tools, and it fits perfectly for my specific Ford model, making it a reliable guardian of grunt.
- Cons: It's too pricey for what it is, and if it fails, the symptoms like rough idling or stalling can lead to a very expensive bad day. Most likely, it's not a long-term solution for everyone, and the precision might be overkill for casual users.
