Rugged, high-endurance transportation like your terrain-mastering Toyota 4Runner are intended to be driven roughly on or off the grid but they must have regular maintenance and quality parts to continue challenging life's dangerous curves. When a problem develops or a component needs to be fixed, don't economize with an unreliable component. That Toyota 4Runner deserves efficiency-optimized car parts to come through with its best performance. Drivers who pick a Toyota realize that reliability and style are well worth the price; outstanding accessories can keep your vehicle on the road. No vehicle boasts a reputation for astonishing durability to nearly match motorcar or trucks from Toyota and their ubiquity is fairly earned. Toyota is known for manufacturing vehicles with enduring dependability and great driver control. For countless years car owners have believed in Toyota to create reliable vehicles that are known for great resale value. The Toyota 4Runner Oxygen Sensor is a system used to monitor the oxygen level in the car's emissions. These sensors are essential devices that are installed in the fuel system to increase fuel performance. Positioned on the exhaust manifold, this device forwards oxygen levels measured in the car or truck's exhaust system to the engine computer. Your car is special due to its high performance and awesome style, and to have it humming in its best condition you want the acme in top-notch parts. No matter the part, brakes and wheels or gaskets and manifolds, fixing a vehicle with top quality parts will pay off, time after time. Driving a Toyota was a good choice, now keeping it in showroom condition is an even better idea. Sometimes the most difficult thing about repairing an older vehicle is searching for a top-rated source of quality parts. Visit www.partsgeek.com every time you need the best quality automotive parts and be rewarded with our great service and a good price every day.

Research on Oxygen Sensor for Toyota 4Runner

All cars that were manufactured after 1980 were mandated to be equipped with an oxygen sensor and so they are. The oxygen sensor is generally located within the emissions control system. The function of the oxygen sensor is to transmit data to your car's engine or to be more precise, to send data to the management computer housed within the engine. This data in turn is processed and used by the management computer to keep the engine running at top performance.

As a secondary function, the oxygen sensor also keeps in check the exhaust gas emissions coming from your car and warns you if and when the numbers are not within prescribed ranges.

How Does My Toyota 4Runner Oxygen Sensor Work?

Different cars have a different number of oxygen sensors depending mostly on the type of engine running. Traditionally V6 and V8 engines come with three sensors, 4 cylinder engines have two sensors and 4 and 6 cylinder inline engines come with three sensors. With respect to the Toyota 4Runner specifically, it may have one or two sensors depending on the model. Oxygen sensors work by measuring the oxygen gasoline ratio (14.7: 1 is an ideal ratio). If the mixture is too rich or too lean, then the sensor creates a voltage which is then presented in the cockpit as warning (check engine light).

How Can an Oxygen Sensor Have Gone Bad in My Toyota 4Runner?

In most modern cars, the oxygen sensors have a life of 100k miles. However, it is not rare, like in the case of the Toyota 4Runner to run into problems prior to this mark itself. The Toyota 4Runner O2 sensor problem may be because the sensor has become caked with chemical compounds such as sulfur, lead, fuel additives, oil, ash, etc. which are all byproducts of combustion. This will basically strip the sensor of its ability to produce and send a voltage if and when the mixture is too lean or too rich. Another common cause for oxygen sensors to become inoperative is the use of low - quality fuels, lack of maintenance, untimely spark plug and air filter changes, etc.

How Much Will It Cost to Replace the Oxygen Sensor My Toyota 4Runner?

Your Toyota 4Runner sensor replacement cost will vary on the model of your 4Runner and your location. For instance, the owner of a 4Runner living in Florida will pay approximately anywhere between $215 - $473 for a 2004 Toyota 4runner 02 sensor replacement. Are you failing emission tests? Is the check engine light on the whole time? It may just be because of a caked oxygen sensor. Order a replacement right here at PartsGeek and get the highest quality spare parts for the cheapest prices!

You may find oxygen sensors for cheaper prices, but sadly, they will simply not be of the same quality and you can consider yourself lucky if they last half as long as your previous one. When it comes to auto parts, the mantra is quality, quality, quality!
