AutoZone’s aftermarket oxygen sensors can keep your engine running efficiently. The engine computer is responsible for calculating how much fuel the engine needs based on the amount of oxygen in the system, and it relies on a good O2 sensor to function properly. The sensor is mounted in the exhaust manifold to monitor the amount of oxygen in the exhaust. Faulty oxygen sensors cannot send the correct air-fuel ratio data to the engine control module, leading to inaccurate guesses about the amount of fuel your engine needs. This is why when the oxygen sensor fails, vehicles can start consuming far more fuel than is necessary.Signs of a Bad O2 Sensor?
Bad O2 sensor symptoms include poor gas mileage, rough engine idle, starting trouble, and even failure of the catalytic converter. Often, the check engine light will come on to provide ODII trouble codes to check with a code reader. Garage replacement service for a bad oxygen sensor can be pricey, but changing your own O2 sensor is generally an easy DIY job that can make your car run smoothly again.
If you've been dealing with the symptoms of a bad oxygen sensor, a new sensor can make your car's emission control and fuel consumption right again. Buy online for free next day delivery or same day in-store pickup.
