Lower car oxygen sensors are an essential component in modern vehicles that help ensure optimal engine performance and fuel efficiency. These sensors are designed to monitor the oxygen levels in the exhaust system and provide real-time data to the engine control unit, which then adjusts the air-fuel ratio to maximise engine efficiency. With regular use, oxygen sensors can become damaged or worn, leading to decreased engine performance and increased emissions. Upgrading to high-quality replacement sensors can help stabilise engine operation and advise on the overall health of the vehicle, making them a worthwhile investment for any car owner.
