Are Bosch oxygen sensors any good?

Our top pick is the Bosch Oxygen Sensor. This sensor will offer you a long service life that's free of contamination. It has a well-engineered design and is fast and efficient. Moreover, it's decently priced and works just as well if not better than higher-priced options.

How long do Denso O2 sensors last?

Even still, the lifespan of a modern O2 sensor may be 60,000 to 90,000 miles. Cars with bad O2 sensors will activate a check-engine light and may idle rough and get poor fuel mileage because they're operating in “open loop” to a pre-determined fuel map.

How long do Bosch oxygen sensors last?

OEM oxygen sensor manufacturers, such as Bosch, work hard to ensure that oxygen sensors last as long as possible. The latest designs can last over 100,000 miles under laboratory bench-testing conditions!

Is Denso a good brand?

Denso is well-known and has a good reputation overall, but so does NGK and so do a number of other top-tier aftermarket (from the perspective of Toyota, but OEM for others) brands.

Are aftermarket oxygen sensors any good?

It's true that you may find an aftermarket oxygen sensor that's advertised as better than OEM. There's still no guarantee that it'll outperform an OEM oxygen sensor when it comes to working with your ECU and withstanding the continuous exposure to hot exhaust.

What happens if you use the wrong O2 sensor?

If your vehicle has a bad oxygen sensor, it could run irregularly or sound rough when it idles. A faulty oxygen sensor can impact your engine's timing, combustion intervals, and other essential functions. You could also notice stalling or slow acceleration.

Can I use any oxygen sensor?

Unless the actual part number on the sensor is a direct and listed (published) catalog interchange for your year, make and model, the sensor will not work as intended. Oxygen sensors last a long time, easily 100,000 miles unless the engine is burning oil in which case the sensor gets contaminated.

Should I replace all O2 sensors at once?

O2 sensors are a "wear item" and are recommended to be replaced every 75k mi. (if I remember correctly, check the FSM). Consider them part of a really proper tune-up regimen. Simply put, they are providing one set of input for your fuel injection system so it can manage things optimally.

How many miles are O2 sensors good for?

Since O2 sensors are so critical to your car's system, it's recommended to replace your sensors every 60,000 to 90,000 miles. There are a few signs that will help you know when it's time to take your vehicle in to have the sensor replaced.

How often should you change oxygen sensors?

All cars and trucks that were made in the last fifteen years should have their O2 sensors replaced every 60,000 to 90,000 miles. Replacing your sensor at these intervals will lower the level of pollution that your vehicle emits while playing a preventive role in the cause of damage to the vehicle.

Which 02 sensor is bank 1 sensor 2?

So all of the oxygen sensors will be bank 1. The oxygen sensor or Air/Fuel sensor closest to the engine in the exhaust manifold will always be Sensor 1. The O2 sensor located in or behind the catalytic converter will be Sensor 2.

Is there a difference in O2 sensors?

O2 sensors, also called lambda sensors or oxygen sensors, measure the proportion of oxygen in vehicle exhaust. Physically, there's no difference between front and back O2 sensors. They function in the same way, but the vehicle's computer uses the measurements that they take for different purposes.

Do O2 sensors degrade over time?

Because the sensors are exposed to very high temperatures when the engine is running, even if the vehicle is parked and idling, they will begin to deteriorate over time.

What brand O2 sensor does Toyota?

OEM stands for "original equipment manufacturer" and Denso manufactures the sensors for Toyota. Therefore Denso is the OEM.

Should you use anti seize on O2 sensor?

Use anti-seize compound to coat on the sensor's threads (some oxygen sensors have the anti-seize compound applied at the factory). When there's no torque value given for tightening the new oxygen sensor, treat it much like you would a spark plug. In other words, less is probably better here.

What company makes oxygen sensors?

It's been more than 40 years since Bosch invented the Oxygen Sensor and began series production in 1976. Today Bosch is the world's largest manufacturer, market leader and the No. 1 aftermarket supplier of oxygen sensors in North America.


Denso is OEM manufacturer. So there isn't really a Denso vs Toyota OEM. It IS Toyota's OEM. You can buy denso like products, but normally they don't compare.

Which is better NGK or DENSO?

Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode's diameter in Denso plugs shrinks more than an NGK. For this reason, Denso plugs do not last longer than NGK units, but they are better at producing powerful sparks.

Who makes DENSO?

After becoming independent from Toyota Motor, the company was founded as Nippon Denso Co. Ltd. (日本電装株式会社, Nippon Densō Kabushiki-Gaisha) in 1949. About 25% of the company is owned by Toyota.

Will a new O2 sensor improve performance?

Those symptoms could also be indications of other problems, but the EPA says that replacing a bad oxygen sensor can improve fuel economy by as much as 40 percent, so clearly that is one place to look if your vehicle develops a greater thirst for gas.

What is the difference between heated and unheated oxygen sensors?

The only difference between the two is that the three-wire sensor shares a common ground between the heater and sending circuits. Therefore, a heated oxygen sensor is more efficient than an unheated sensor.

Who makes Toyota sensors?

Registered. Denso makes the Toyota sensors. Amazon has the Denso TPMS for half the price of what you say Toyota wants them for. I changed one of my dead one out with this Denso TPMS.

Which O2 sensor usually goes bad?

Which o2 sensor usually goes bad? Which o2 sensor goes bad first? The main o2 sensors go bad first from the crap that flows & burns through them (Gas).

Can oxygen sensor cause loss of power?

Can A Bad O2 Sensor Cause Loss Of Power? Yes, loss of power can be a symptom of a bad O2 sensor typically caused by engine misfires. When the ratio of oxygen to fuel is thrown off, your engine will struggle to function optimally and you may feel like your car is sluggish and not driving well.

Which O2 sensor is more important?

the front oxygen sensor in the exhaust manifold is "most important" because it is used for fuel control. the rear heated oxygen sensor is only used to monitor the operation of the catalytic converter.

Are 02 sensors universal?

Regular O2 sensors, now called Narrow band, output a voltage of . 1 to . 9 volts, depending on Oxygen levels in exhaust. Upstream or downstream , left or right, doesn't matter, Ford, GM, Dodge, doesn't matter, they are all interchangeable if wire and connector match up.

Should you reset ECU after replacing O2 sensor?

The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle's computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Once you've replaced your vehicle's O2 sensor, you'll need to reset the ECU so it can properly gather information from the new O2 sensor.

Why does my check engine light stay on after replacing O2 sensor?

The check engine light could be caused by more than one problem. Your oxygen sensor may have been replaced by the technician, but your spark plugs need to be replaced as well.
