The number of oxygen sensors in a Subaru Forester can vary depending on the vehicle configuration and model year. However, there are generally two to five oxygen sensors in Subaru vehicles.

How much does it cost to replace the oxygen sensor on a Subaru Forester?
AutoNation Mobile Service offers upfront and competitive pricing. The average cost for Subaru Forester Front Oxygen Sensor Replacement is $337.
Do you need to replace both upstream and downstream O2 sensors?
Yes, you have to replace 2 Oxygen sensors if your car has one catalytic converter with one exhaust pipe. One sensor is in the front and another one is after the catalytic converter and remember don’t mix them up, the one for upstream before the catalytic converter is different from the one behind the converter.
How do I know which O2 sensor is bad?
What Are the Symptoms of Bad Oxygen Sensors?
- Oxygen Sensor: How it Works. Most oxygen sensors generate an electrical signal that tells your car’s Powertrain Control Module how much to alter the air-fuel mixture.
- Illuminated Check Engine Light.
- Poor Gas Mileage (Plus Bad Smells & Black Smoke)
- Poor Engine Performance.
What are the 3 common causes of O2 sensor failure?
Below are the top reasons that cause the oxygen sensor to fail:
- Long Time Usage. The oxygen sensor as with all electrochemical sensors, loses sensitivity after long periods of use.
- Contamination.
- High Temperature.
- Irregular Maintenance.
- Using Low-Quality Gasoline.
Can I drive with a failing O2 sensor?
Can I Drive My Car With A Bad Oxygen Sensor? We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture. While it may perform fine in the beginning, if your engine is running rich and using too much fuel it might begin to clog the catalytic converter.
Should I replace all O2 sensors if one is bad?
It is best to replace O2 sensors in pairs. For example, if you replace the downstream left sensor, you should also replace the downstream right. However, on most vehicles produced since 1996, replacing one sensor (especially the front engine monitoring sensor) will cause the ECU to set a code for the other sensors.
What happens if you drive with bad oxygen sensors?
Is It Okay To Drive My Car If It Has A Bad Oxygen Sensor? We recommend not driving with a bad oxygen sensor as the powertrain isn’t running on the correct fuel mixture. Though it may seem fine, if the powertrain is running rich and over-using its fuel it could start to clog the catalytic converter.
How many 02 sensors does a Subaru Forester have?
Oxygen sensors are a critical component of the fuel and emissions systems on your vehicle. This tubular device is usually found connected to the exhaust manifold or to the catalytic converters. Subaru vehicles generally have two to five oxygen sensors.
What happens when both O2 sensors are bad?
A functional O2 sensor will be an essential cog for a consistent running vehicle. Still, a bad oxygen sensor will most likely cause bad fuel economy, bad smells in your car, and tamper with your engine’s performance ability.
Where is the oxygen sensor on a Subaru Forester?
And so we have electric connectors the connect here. And so we just need to squeeze. The depress on the back here. And then be able to pull the electric connector on time.
