Subaru Oxygen Sensors

Refine Results

Car exhaust flows have oxygen sensors that detect how much unburned oxygen your engine emits. This sensor then sends voltage to your engine control unit to determine if the air-fuel mixture in your engine is too lean or rich. SubaruOnlineParts offers a quality selection of exhaust sensors for select Subaru vehicles.

Enjoy Optimal Engine Performance with Top-Quality O2 Sensors

Oxygen sensors monitor how much oxygen your exhaust stream has, and ensure that your catalytic converters are working through oxygen level checks. Exhaust sensors oxidize some oxygen as it passes through the exhaust. These auto parts then turn this reading into a voltage signal and transmit it back to your engine control unit (ECU). Once your ECU detects that the air-fuel mixture is too rich or lean, the unit will increase or decrease the amount of fuel to achieve the optimal A/F ratio.

O2 sensors can either be binary or universal sensors. Binary sensors compare the excess oxygen in your exhaust with ambient air oxygen levels. They determine when a rich air-fuel mixture gets lean and vice versa. Universal exhaust sensors have a greater measuring range than binary sensors and are compatible with both diesel and gasoline engines.

Find the Best Oxygen Sensor for Your Subaru Online

Oxygen sensors are extremely durable, but can still fail over time. Contaminated fuel, carbon deposits from an engine burning oil, and external pollutants can cause these sensors to fail. The fuel economy and overall performance of your car will also falter should your O2 sensor start to malfunction. Replace these parts whenever necessary and maintain an efficient gas mileage for your Subaru.

SubaruOnlineParts carries genuine exhaust sensors in its online catalog. These top-quality auto parts are compatible with select Subaru models. All of our sensor replacements are 100% genuine, brand new, easy to install, and sold for less than the manufacturer’s suggested retail price. Browse our website today to get the best O2 sensor at discounted rates for your car.

Frequently Asked Questions About Subaru Oxygen Sensors

What does a car oxygen sensor do?

A car oxygen sensor or an O2 sensor is part of the exhaust system in cars. It measures the proportion of oxygen present in your engine to check its air-fuel ratio. These sensors are often found incorporated into the exhaust pipes of cars and located near the passenger side of the car. Cars can have one to four oxygen sensors, depending on their exhaust setup.

How do I know if my car’s oxygen sensor needs replacement?

Having a faulty car oxygen sensor can reduce its fuel efficiency by up to 40%. If your car is constantly failing emissions tests and has different performance issues like rough idling, stalling, and other similar complications, the oxygen sensor of your ride needs to be replaced right away.

How long should O2 sensors last?

The functional lifespan of oxygen sensors for cars varies due to numerous factors like their model and design. For instance, the sensors of older vehicles usually last from 30,000 to 50,000 miles, while newer models with an additional heated feature can last up to 100,000 miles.

Can I clean my car’s oxygen sensors?

Yes, you can clean these sensors. Cleaning your vehicle oxygen sensors requires specific cleaners to break down the accumulated grease and debris in the sensors without damaging them. Make sure to return it properly and take your car for a spin to test out if the sensors are working well after cleaning.

How to replace an oxygen sensor?

The first step you need to do when replacing these sensors is to locate them near the catalytic converter and remove them from its wiring harness. You can spray the area with penetrating oil to lubricate the site and make it easier for you to remove them from your exhaust pipe. Once you remove your old sensor, you can install the new one by screwing it tightly into place.
