What a TPS sensor does

The throttle position sensor tells your engine computer how far the throttle is open. When it fails you get hesitation, surging, a bad idle or limp mode. The short version, with the two drawings that explain nearly every TPS fault.

The throttle position sensor sits on the throttle body, on the end of the throttle shaft. It gets a 5 volt reference and a ground from the engine computer and returns a signal voltage that rises as the throttle opens. Code references cite roughly 0.5 volts at idle and 4.5 volts at full throttle as a typical pattern, but the exact numbers for your engine are in its service manual (OBD-Codes.com).

Classic sensors are a potentiometer: a wiper sliding along a resistive track. When the track wears, the signal drops out at one spot, and the engine stumbles there. Some sensors read a magnet with no contact at all (SMP listing).

On an electronic throttle, there is no cable. A motor opens the throttle, and two position signals inside the throttle body are compared constantly. When they disagree you get P2135 and usually reduced power.

TPS trouble codes

Six generic OBD-II codes cover most throttle position faults. The last word of the title tells you where to look first.

Separate sensor, or built into the throttle body?

This one question decides what you buy and what it costs.

TPS

Cable throttle

A cable runs from the pedal to the throttle body. The TPS is usually a separate part on two screws. Some older ones are adjustable.

Replace a TPS

MOTOR + TPS

Electronic (drive by wire)

No cable; a motor moves the throttle. The sensors are usually inside the throttle body, so the fix is often a throttle body.

Buying a TPS sensor

Fitment beats brand. Match the part to your VIN or the number on your old sensor, then choose between OEM and aftermarket.

Who makes replacement throttle position sensors. No rankings: fitment matters more than the logo.

Questions people ask

What does a TPS sensor do?

The throttle position sensor tells the engine computer how far the throttle is open. The computer uses it for fueling, idle control, and on many automatics, shift timing. Most send a voltage on a signal wire that rises as the throttle opens, from a 5 volt reference.

What are the symptoms of a bad TPS sensor?

Hesitation or stumbling when you press the gas, surging, a rough, low or racing idle, stalling, odd automatic shifts, reduced power on electronic throttles, and a check engine light with codes such as P0120 to P0124 or P2135.

Can I replace a TPS sensor myself?

On a cable throttle with a separate sensor, usually yes: a plug and two screws, then a check of the closed-throttle reading and any relearn your vehicle needs. On electronic throttles the sensors are usually inside the throttle body, which is a bigger job.

How much does it cost to replace a TPS sensor?

Published estimates for a separate sensor run roughly $120 to $355 at a shop, mostly labor. A sensor built into an electronic throttle body can mean $300 to $800 or more. See the cost guide for sources.

Is a TPS sensor the same as a tire pressure sensor?

No. TPS is the throttle position sensor on the engine. The tire pressure sensor is TPMS, fitted in each wheel. If the warning light on your dash is a tire symbol, you need a TPMS fix, not a TPS.
