Precision Throttle Position Sensor

Engines need to constantly adjust air intake to deliver plenty of power when you need it, and keep idle steady when you let off the throttle. So how does the control system know how much air to feed the engine? It’s all down to the Throttle Position Sensor (TPS). The TPS ensures smooth, responsive throttle control for easier operation. Don’t let a faulty sensor slow you down. From excavators and trucks to ATVs and more, FridayParts has high-quality TPS sensors for all kinds of equipment. Find the perfect fit for your machine now, and get your engine’s snappy response back in no time.

Common Symptoms of a Bad Throttle Position Sensor

A faulty TPS sends wrong data to the ECU, and that causes all sorts of obvious performance issues. If you notice any of these problems, the TPS is probably to blame:

• Check Engine Light comes on: It’ll throw diagnostic trouble codes linked to the TPS circuit or how it’s working.
• Hesitation or stalling when accelerating: The engine might struggle to speed up smoothly, or even die out. That’s because the ECU isn’t getting the right info about how much power you need.
• Rough or erratic idle: The idle speed could be too high, too low, or jump around for no reason. The ECU is just trying and failing to get a stable air-fuel mix.
• Trouble with transmission shifting: On automatic transmissions, a bad TPS can make shifts happen late, feel rough, or be all over the place. Shift points usually rely on throttle position data.
• Worse fuel efficiency: A messed-up air-fuel mix almost always makes the engine burn more fuel than it needs to.
• Sudden power surges or lack of power: Your vehicle or machine might lurch forward out of nowhere, or feel like it’s lost a ton of power while you’re using it.
