Blurb: Looking to optimize your vehicle's performance? Learn about the crucial role oxygen sensors play in keeping your car running smoothly! Oxygen sensors are small but mighty devices that continuously monitor the oxygen levels in your vehicle's exhaust gases. By relaying this information to the Engine Control Unit (ECU), they help adjust the air-to-fuel ratio, ensuring efficient combustion and minimizing harmful emissions. Spotting signs of faulty oxygen sensors early can prevent costly repairs and keep your car running smoothly. Look out for decreased fuel efficiency, rough idling, or a check engine light on your dashboard. Keep your vehicle in top shape at Johnny’s Auto Service!
