Air Flow Meter Sensor Replacement ?

Why This Sensor Is Important

Your vehicle's engine needs the right mix of air and fuel to run smoothly. This sensor monitors the amount of air entering the engine. With this data, the car's computer adjusts fuel delivery for best power and economy. Without accurate air flow measurement, your engine can't run at its best.

How the Air Flow Sensor Works

The sensor sits between the air filter and the throttle body. As air moves past a heated wire or film, the sensor detects changes in temperature or voltage. It sends signals to the engine control module, ensuring the fuel injection system delivers just the right amount of fuel.

What Happens If It Breaks?

A faulty sensor can cause rough idling, stalling, reduced fuel efficiency, hard starting, or even trigger the check engine light. Long-term driving with a bad sensor can damage your catalytic converter and affect emissions.
