Yes, a malfunctioning oxygen sensor can significantly reduce the fuel efficiency of your Suzuki Alto.

How It Works: The oxygen sensor monitors the level of oxygen in the exhaust gases and sends this data to the engine control unit ECU. The ECU uses this information to adjust the fuel-to-air ratio. If the oxygen sensor is faulty, the ECU may not get accurate information, leading to an incorrect air-fuel mixture.
Impact on Fuel Economy: A bad oxygen sensor can cause the engine to burn too much fuel, increasing fuel consumption. It may also cause the engine to run rich too much fuel o r lean too little fuel, both of which can harm fuel economy.
Symptoms of a Faulty Oxygen Sensor: Poor fuel economy, engine misfires, rough idling, o r the Check Engine light coming on are common signs of a faulty oxygen sensor.
Solution: If you suspect a malfunctioning oxygen sensor, it’s best to replace it as soon as possible. This will restore proper fuel management and improve fuel economy.
