Essential Sensor for Engine Efficiency ?

Why You Need This Part

This advanced sensor is vital for measuring the oxygen level in your car's exhaust system. It ensures your engine receives the correct fuel-to-air ratio for efficient combustion. This leads to better fuel economy, smoother performance, and lower emissions.

How It Works

The sensor monitors and sends real-time oxygen level data to the engine control unit (ECU). The ECU makes continuous adjustments to the fuel mixture, keeping your engine at peak efficiency. It plays a key role in modern emission control systems, directly influencing how your engine runs.

What Happens If It Breaks?

If the sensor fails, the ECU may use incorrect data to mix fuel and air. This causes poor fuel efficiency, increased emissions, rough idling, and even engine warning lights. Ignoring a bad sensor can damage other engine components and fail emission tests.
