What Brand of O2 Sensor Does Honda Use?

Do you know the Honda oxygen sensor plays a vital role in diagnosing fuel efficiency and engine performance problems?

Now you know. It is essential to know the brand Honda uses. Why?

Honda automobiles use Denso O2 sensor brands. Denso is the original equipment manufacturer for Honda vehicles. They manufacture different parts for Honda cars, including oxygen sensors. You will also find other brands with aftermarket versions of these parts.

What Brand Oxygen Sensor Does Honda Use?

Honda uses the Denso brands for various sensors you will find in your car. In addition, Denso manufactures automobile parts for various vehicle companies.

The primary base of this establishment is Japan.

You might assume that the company origin is why this is the top choice for Honda automobiles. Honda, as you know, is also an Asian company.

But findings have shown that this is most likely not the case. Why do we say so?

Denso is firstly known not for its location but it’s quality. The O2 sensors are no exception.

Most reviews and buyer’s guide in the automobile world ranks Denso Brands as one of the top three in the automobile world.

Various vehicle users’ comments and experiences show how good the Denso oxygen sensors function.

These reviews further establish the Honda vehicle as one of the most fuel-efficient cars. 

Functions of Honda Oxygen Sensor

The oxygen sensor’s main function is data collection. It collects combustion data and sends it to the engine computer.

This data shows just how efficient the car is in burning fuel. It also shows the fuel-to-oxygen ratio. 

Burning rich is when excess Oxygen burns with the fuel during combustion while burning lean is the phrase for when the fuel is burning in low Oxygen

The oxygen sensors are in different parts of the engine. Together they form a system that detects excess emissions by comparing the oxygen level in the air and the emission level.

Excess emissions affect the engine. This effect, in turn, has a bearing on the car’s performance.

In addition, it determines if you will spend more money on fuel for lesser mile coverage or if you will spend more on repair and maintenance of your engine.

Prevailing Symptoms of a Faulty Oxygen Sensor

The Oxygen is located deep in your car mechanism. It is not something you can easily check for faults or errors.

However, some typical symptoms or signs can help point to the car’s faulty oxygen sensor. They are as follows:

#1. Engine Performance Reduces

The engine performance rating reduces by almost 40% when emissions become a problem due to faulty sensors.

Note that the engine has to burn more fuel to maintain its primary function. More fuel consumption can lead to issues sure as engine misfiring. 

#2. Fuel Efficiency

The engine burns more fuel, especially in a burning rich situation. That means you get to spend more on fuel than your standard rate.

This extra spending is a quick way to observe changes in your vehicle system functions. 

Considering its function and the effects of a faulty sensor, one needs to be able to detect faults quite early before it runs deep into the car systems.

#3. Check-Engine Light

When the Honda oxygen sensor becomes faulty, it affects the engine function. One quick way to notice any faults is through the light on the board.

No one wants to see this light come on, especially when you are about to go on an important journey.

However, the check engine light shows that the car needs immediate attention. More often than not, the oxygen sensor is faulty and needs replacement. 

Are All Honda O2 Sensors the Same?

Honda O2 Sensors

A car will have various oxygen sensor types. While the functions might be similar, the sensors are not a kind. You can’t interchange these sensors. 

Two different oxygen sensors exist in a car, depending on the location. 

#1. Upstream Sensors or Front Oxygen Sensor

The front oxygen sensor sends information from the engine exhaust to the car engine. The function is to monitor oxygen levels at this site.

The engine computer uses this information to alter the ratio and correct the imbalance.

#2. Downstream Sensors or Rear Oxygen Sensor

Final emissions pass through the catalytic converter; this is where the second type of oxygen sensor comes into play.

The downstream sensor measures the oxygen level at this junction. Again, the engine compares the readings to the front sensor, making necessary adjustments. 

Other than the types and location, another factor sets apart each oxygen sensor. This factor is the unique oxygen sensor number.

It is different for each year of manufacturer. It makes it easier to get a compatible replacement. 

Which Brand of the O2 Sensor is Best?

When you have a faulty oxygen sensor, the next step is to change it before it causes significant damage. Don’t replace it with anyone you find but with quality products.

This dilemma brings the question, “Which brand of the O2 sensor is the best?”

A quick market survey will help answer this question. However, it is essential to note that most vehicle users often opt for the safe option.

The users buy replacements from the same brand.

In cases involving Honda, this is the Denso brand. But if you must look for other brands, you can fish for the oxygen sensor of liking from a pool of healthy choices. 

The ranking for best O2 sensors considers multiple factors, so that you might find more than one name on this list.

#1. Top Quality O2 sensors

While many options are available to you in the oxygen sensor market, it is vital to note top-quality options.

Other than the default Denso brand, there are two others you might want to consider.

#1. Bosch Oxygen Sensor

This first should come as no surprise, especially when you remember that the inventor of the oxygen sensor was Robert Bosch.

The Bosch company focuses mainly on producing aftermarket components.

The company has much success in its production unit. This brand has the best-seller product.

#2. ACDelco Oxygen Sensor

ACDelco prides itself in manufacturing one of the best oxygen sensors at the most affordable price.

So when you compare quality while considering price as a factor, ACDelco is one of the cheapest.

What’s more? The reasonable price does not affect its quality, so you will find it on this list.

#2. Criteria for Ranking

The brand’s selection was not a name from a heart process. The selection was after much road testing. These were the criteria for selection: 

#3. Accuracy

Accuracy is perhaps the most important factor when ranking the different oxygen sensors available in the automobile market today. Accuracy helps to detect changes and fixes quite early.

In addition, the more accurate a sensor is, the more you trust the readings and data sent to the engine computer. 

This accuracy will help improve the performance of the engine.

#4. Year of Manufacture

The year of manufacture gives insight into the makeup of the oxygen sensors. It also determines the design. Compatibility is essential when there are differences in design. 

If it is not compatible, you have to search further. Hence there is a need to check more than just quality when selecting a sensor.
