What it is & what it does

The throttle position sensor (TPS) tells the engine computer the throttle angle — how far you’ve pressed the accelerator — so it can deliver the right fuel and respond smoothly. On drive-by-wire cars it works with the pedal sensor.

Accurate signals mean smooth, responsive driving.

Signs of trouble & how we help

A faulty TPS causes hesitation, surging, rough idle, poor response, or a check-engine/EPC light. Symptoms can be intermittent and frustrating.

We read live throttle data to confirm the sensor and, where needed, perform a throttle adaptation after replacement.
