Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
Moreover, where is the O2 sensor on a RAV4?
People ask also, where is the O2 sensor located on a 2008? The sensor is typically located on the passenger side of the car, mounted directly onto the exhaust pipe near the catalytic converter. When the sensor goes bad, your car may lose up to 40 percent of its fuel efficiency, because your car will use too much gas.
You asked, how many oxygen sensors does a 2004 Toyota RAV4 have? Most cars also have an oxygen sensor after the catalytic converter to help gauge converter efficiency. Again the RAV4 has two.
In this regard, where is the O2 sensor on a 2007 RAV4? The sensor is located at the top of the exhaust manifold for bank 2.

How many O2 sensors does a 2001 Toyota RAV4 have?
The 2001 Toyota RAV4 haS4 oxygen sensors. The coolant needs to be changed every 60,000 miles or so.
How much is it to replace an O2 sensor?
The Average Cost to Replace an Oxygen Sensor Is $155 to $500 Depending on if You Go to the Mechanic or DIY.
How do I fix code P0137?
- Replacing the O2 sensor for bank 1 sensor 2.
- Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
- Repairing exhaust leaks before the sensor.
What causes code P0138?
When trouble code P0138 is set, this indicates that there is a high voltage (steadily above . 9 volts) for more than 10 seconds indicating a lack of oxygen in the exhaust stream and an abundance of fuel at sensor 2 on the bank 1 of the engine.
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.
How can you tell which O2 sensor is bad?
- A Glowing Check Engine Light. The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor.
- Bad Gas Mileage.
- An Engine That Sounds Rough.
- An Emissions Test Failure.
- An Older Vehicle.
How many O2 sensors does a V8 have?
Therefore, while most vehicles have two oxygen sensors, those V6 and V8 engines equipped with dual exhaust have four oxygen sensors — one upstream and downstream of the catalytic converter on each bank of the engine.
How many oxygen sensors are in a 2002 Rav4?
Jfdhelton, same thing is happening to me on my 2002 with 90K. I have replaced all 4 sensors (2 air/fuel, 2 O2) and thought it was crazy.
How do you test a Toyota oxygen sensor?
Make Engine Run Too Lean Disconnect the hose between the PCV valve and the intake manifold. Turn the engine on and then check the reading on the voltmeter. It should quickly read close to 200mV. If the reading is higher, or the sensor reacts slowly you’ve got a broken oxygen sensor.
What does heater control circuit low mean?
This refers to a problem with the heater element circuit of the HO2S. It’s triggered when the PCM (powertrain control module, also called ECM or engine/electronic control module) detects an excessive low voltage through the HO2S.
