As another user pointed out, you have two O2 sensors. One is in front of the front CAT, the other is behind it.
Correspondingly, how many O2 sensors does a 2005 Subaru Outback have? 2 (one on each side) right by the exhaust manifold, two (one on each side) after what look to be catalytic converters and one right after the second catalytic converter.
In this regard, where is the oxygen sensor on a Subaru Outback? The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system.
Considering this, how many O2 sensors does a 2006 Subaru Outback have? Registered. You have four sensors. Two pre-cat, and two post-cat. All four will affect fuelling and the performance of your car.
Likewise, how many O2 sensors does a 2001 Subaru Outback have? Only 2 one right infront of the front cat that one needs to be a non generic ie OEM the rear one rarely needs replacement but a generic one will work.

Where is the O2 sensor on a 2004 Subaru Outback?
Where are the O2 sensors on a 2005 Subaru Outback?
Locate the oxygen sensor connected to the exhaust pipe. Follow the pipe attached to the exhaust manifold. The sensor has a cylindrical body, about the size of a spark plug and three wires coming out of the rear of the sensor that lead to an electrical connector.
How many O2 sensors does a 2011 Subaru Outback have?
- all 4 sensors are easily accessible from under the car.
Should I replace all O2 sensors at once?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream). An older, slower sensor can cause an imbalance in the engine management system, leading to poor fuel economy and possible damage to the catalytic converter.
Where is the oxygen sensor on a 2006 Subaru Outback?
The downstream unit will be on the exhaust pipe as it goes around the passenger side of the engine and the upstream unit is in front of the engine. You don’t really need the wrenches either if you have standard line wrenches.
Are all O2 sensors the same?
O2 sensors, also called lambda sensors or oxygen sensors, measure the proportion of oxygen in vehicle exhaust. … Physically, there’s no difference between front and back O2 sensors. They function in the same way, but the vehicle’s computer uses the measurements that they take for different purposes.
How much should an O2 sensor replacement cost?
The Average Cost to Replace an Oxygen Sensor Is $155 to $500 Depending on if You Go to the Mechanic or DIY.
How many oxygen sensors does a 2009 Subaru Forester have?
You have two O2 sensors. Front/upstream O2 sensor (Air/Fuel) & a rear/downstream O2 sensor. Any chance they changed “other” sensors & not just the O2 sensor?
Which side is Bank 1 on Subaru?
The Subaru Impreza bank 1 sensor 1 is located on the passenger side of the exhaust before the catalytic converter.
What side is bank 1 sensor 2?
Bank 1 sensor 2 is located downstream, usually right behind the catalytic converter. Regardless of the bank, all oxygen sensors use the same naming pattern. One that is between the engine and the catalytic converter is upstream or sensor 1.
