The emission control system of your vehicle consists of various components, including oxygen sensors, catalytic converters, throttle actuators, etc. that work together to limit the discharge of harmful gases into the atmosphere. The main purpose of the sensor is to monitor the air fuel ratio and send these data to the engine computer. If the sensor is failing, it can send incorrect information to the computer which may lead to drop in power output if the air fuel mixture is too lean or decrease in fuel efficiency if the mixture is too rich. So don’t forget to check your sensors for damages and replace them in time to ensure optimal engine operation.
