SpeedFactory Throttle Position Sensor for B/D/F/H Series

SpeedFactory Racing Throttle Position Sensor (TPS) - Honda B, D, F & H Series (SF-01-101)

Nobody shops for a throttle position sensor for fun. You're here because your car is doing something weird, or because you've got a throttle body on the bench and the old sensor looks its age. Either way, this is the straightforward fix. It's a direct factory replacement for Honda and Acura B-series, D-series, H-series, and F-series (Accord only) engines, it comes with new mounting hardware and a gasket, and SpeedFactory backs it with a 1-year warranty. Bolt it on, set it properly, and your car goes back to behaving.

Signs Your Throttle Position Sensor Is Going Bad

The TPS is a potentiometer that tells your ECU exactly where the throttle plate is sitting, and the ECU leans on that reading for fueling and ignition timing. When it starts wearing out, the readings get noisy or drop out entirely, and the symptoms are frustrating precisely because they're inconsistent. Here's what people usually notice: a surging or hunting idle that won't settle, a stumble or hesitation right off idle when you get on the throttle, a random stutter at steady cruise, or an automatic that shifts erratically because it's getting bad throttle data. On OBD2 cars you'll often pull a P0122 or P0123. If you've been chasing a driveability gremlin and already looked at the usual suspects, a worn TPS is a genuinely common culprit and a cheap one to rule out.

Set It, Don't Just Bolt It On

This is the part almost nobody tells you, and it's the difference between a sensor that fixes your problem and one that creates a new one. The TPS is adjustable, and you need to set it, not just torque it down wherever it lands. If it reads zero at closed throttle, the ECU can drop into fuel cut, and you'll be right back to a car that doesn't drive right. The usual target is a small amount of open, commonly checked as roughly 0.45 to 0.5 volts at closed throttle on the signal wire, but confirm the correct spec for your specific engine and ECU setup before you finalize it. Loosen the mounting screws, rotate the sensor until you're where you should be, then snug it down and verify. Five extra minutes with a multimeter or your tuning software saves you a week of head-scratching.

Use The Gasket

Small thing, big consequence. SpeedFactory includes a sealing gasket, and it's not optional hardware you can skip because the old one looked fine. That gasket keeps moisture out of the sensor's internal circuitry, and water getting in there is exactly how these die early. Install the new gasket, every time.

Fits B, D, F & H Series Honda And Acura

This TPS covers Honda and Acura B-series, D-series, H-series, and F-series (Accord only) engines across a wide spread of chassis:

It also works on swaps and aftermarket throttle bodies running these engine families. If you're piecing together a B-swap or replacing a sensor on a used throttle body, this is the one.

Who Should Grab This Sensor

This is for anyone chasing an idle or throttle gremlin on a B, D, F, or H series car, or building a throttle body back up and wanting a fresh sensor rather than whatever came on the junkyard piece. These are wear items with moving internals, so on a car that's now decades old, a tired TPS is more likely than not. Grab it, set it right, and get your throttle response back where it belongs.
