Number of Oxygen Sensors in a Toyota 4Runner
The Toyota 4Runner typically has two oxygen sensors. There is one sensor located before the catalytic converter (upstream sensor) and another after the catalytic converter (downstream sensor).
It’s important to note that the number of oxygen sensors can vary depending on the specific model year and engine type, so it’s always best to consult the vehicle’s manual or a trusted mechanic for precise information.

How much does it cost to replace 4 O2 sensors?
Many sensors, nonetheless, cost between $20 and $100. Your mechanic’s labor costs also likely vary based on a few factors, including how difficult it is to access your sensors. Typically, labor costs for a sensor replacement are around $150.
How many O2 sensors does a 2008 Toyota 4runner have?
4 total. 2 AFM are upstream of the cats, 2 O2 sensors are downstream. Theyre on each respective side of the exhaust tubes coming down from the manifold.
How many oxygen sensors does a Toyota have?
Your exhaust system has up to four oxygen sensors depending on the engine size and exhaust layout. If one fails, your ECU will not receive accurate information on your engine’s emissions and may end up reducing your engine’s performance. Read more about oxygen sensors and how they work here.
How much does it cost to replace the O2 sensor on a Toyota 4runner?
Labor costs are estimated between $163 and $205 while parts are priced between $308 and $330. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
How many oxygen sensors does a 2005 Toyota 4runner have?
Your vehicle should have 4 sensors in total, 2 for each bank of the engine. 1 is upstream and is the air fuel ratio sensor and 1 is downstream and is the heated oxygen sensor.
Should I replace all 4 O2 sensors at once?
Do I need to replace all of the sensors at once? 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.
How many O2 sensors does a v6 have?
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.
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 many oxygen sensors does a 2007 Toyota 4runner have?
2
Oxygen Sensor. Built from 06/2007. Bosch validated oxygen sensor. Quantity per car: 2.
Are oxygen sensor 1 and 2 the same?
What is Sensor 1 & 2? The sensor number is telling us where on the exhaust system the O2 sensor or Exhaust temperature sensor is mounted. The 1st sensor is located closest to the engine and the last is located at the rear of the exhaust system.
