Essential Sensor for Optimal Engine Performance

The air fuel ratio sensor is a critical component in modern vehicles, ensuring that your engine runs efficiently and with minimal emissions. This sensor acts as the brain for your vehicle's fuel delivery system, constantly monitoring the mix of air and fuel entering the engine.

Why You Need This Sensor

Every internal combustion engine requires a precise mix of air and fuel for optimal performance. Too much air or fuel can lead to inefficiency and increased emissions. This sensor guarantees the ideal ratio, promoting efficient combustion and safeguarding the environment.

Working Mechanism

The sensor sends real-time data to the engine's control unit, adjusting the fuel injectors' operation to maintain the optimal air-fuel mixture. It sits in the exhaust stream, measuring oxygen levels and communicating any discrepancies to the ECU for immediate correction ?.

Consequences of a Faulty Sensor

If the sensor malfunctions, the engine may run too rich or too lean. This can result in decreased fuel efficiency, increased emissions, and even potential damage to the catalytic converter. The vehicle might also experience rough idling, engine misfires, and poor acceleration.
