Acceleration sensor (throttle)

The acceleration sensor (throttle) is an essential part of a modern vehicle’s electrical system and engine management, replacing the traditional throttle cable. It detects the pressure applied to the accelerator pedal and sends an electronic signal to the engine control unit, which then adjusts fuel injection and airflow accordingly. Accurate sensor response ensures smooth acceleration, fuel efficiency, and responsive engine behavior.

This sensor is typically located near or on the accelerator pedal and is wired into the vehicle’s electronic control system. When it malfunctions, symptoms may include delayed throttle response, reduced power, erratic engine behavior, or a check engine light. Common causes include contamination, wear, moisture damage, or broken wiring.

Replacing the sensor requires either new car parts or reliable used car parts from an auto parts shop, spare parts shop, or auto shop. Many drivers turn to online car spare parts stores, comparing options via a car parts catalog or online marketplace to find affordable or secondhand car parts. For emergencies, 24-hour auto parts services are useful. For guaranteed compatibility, choose from the original parts catalog. It’s also advisable to inspect other engine parts and electrical equipment to ensure full vehicle functionality.
