Do all O2 sensors work the same?

Even though both O2 sensors are four wire, heated O2 sensors, there are definitely differences that the Motronic can detect. You must use the correct ones, whether oem with the correct length cable and plug, or the correct "universal" equivalent, that will require you to measure and splice your old plug onto it.

Are all oxygen sensors the same on every car?

Due to the ODB-II regulations that apply to cars manufactured in 1996 and after, many newer cars have multiple O2 sensors. In fact, some cars have as many as four oxygen sensors. Cars made in 1996 and after are required to have a second oxygen sensor that is located below the catalytic converter.

Is oxygen sensor Universal?

O2 sensors are universal in their function, but I believe they come in different size threads. Sense you have the O2s laying around I would crawl under the front of your car and pull the front O2 sensor and compare, if the threads are the same, you are good to go. Should take 5 minutes to pull off the front bank.

Can you use any O2 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. The other issue is unless the sensor is really old, it should be tested prior to condemning it.

Are Bank 1 and Bank 2 O2 sensors the same?

Bank 2 Sensor 1 is the first sensor closest to the engine. On Bank 2 means it is at the engine side with cylinders 2, 4, 6, 8, etc. Bank 2 Sensor 2 is the second sensor on the engine's exhaust pipe, usually behind the catalytic converter.

What happens if you put the wrong oxygen 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 you use aftermarket oxygen sensors?

Aftermarket parts are usually not covered by a warranty. If an aftermarket oxygen sensor fails prematurely, you have no choice but to buy a new one. The costs can add up over time. All in all, OEM is a safer bet than aftermarket when it comes to oxygen sensors.

Do upstream and downstream 02 sensors look the same?

No you can't just look at them and tell the difference because it's in the internal electrical design. Most older Honda's use 1 of each sensor. The upstream is NARROW BAND and downstream is WIDE BAND. Upstream is before the Cat and downstream is after the cat.

Should you replace all O2 sensors at the same time?

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.

Are all O2 sensors created equal?

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.

Are all 4 wire oxygen sensors the same?

They ARE all different. I have used on my 5.2 motronic 355 both the factory oem Bosch pre-cat O2 sensor #13819 and the Bosch "universal" equivalent, # 15730 which required me to splice my old plug onto it. Both worked perfectly.

Are there different size O2 sensors?

O2 sensors are all pretty much standard in size.

Do I have to replace all 4 O2 sensors?

As long as these values are in range there is no need to replace them. Buying all four at once can also be quite pricey . Buying all four is a waste of money since the two downstream sensors rarely fail and pretty much never wear out.

What is the difference in o2 sensors?

The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter. The upstream sensor monitors the level of pollutants in the engine's exhaust and sends this information to the ECU that continuously adjusts the air-fuel ratio.

Are pre and post cat o2 sensors the same?

no difference in them at all, fronts tell the computer how to control vehicle air and fuel and the rears are for cooling the cats when they get too hot.

Can you drive without a upstream o2 sensor?

Can you drive without an upstream o2 sensor? Yes, you can drive for a short distance without an upstream o2 sensor. However, for a long drive, the ECU would detect there is no fuel in the exhaust and hence would inject more fuel to compensate.

Can you mix O2 sensor brands?

it shouldnt. as long as they are both the correct sensor for your application they should both work fine with your car. yup... shouldnt matter as long as they are the right ones for each bank!

What brand of oxygen sensor is best?

Who makes good O2 sensors?

Will an O2 sensor work without a catalytic converter?

The in-cat or after-cat O2 sensors are just used to check the efficiency of the cat itself. Therefore, in most modern vehicles a car can run just fine without a cat.

Can you bypass O2 sensors?

Should You Bypass Oxygen Sensors? Bypassing the oxygen sensor with a dummy can be done. Many people will do this to get the Check Engine Light to turn off when emissions aren't right or to allow for more flexibility when tuning the engine.

Can you put the wrong O2 sensor in a car?

Typically, you cannot repair a faulty O2 sensor. It must be replaced because of the technology and materials in its housing. There are some DIY places that will tell you how to clean the sensor to get a few more miles out of it, but you're only delaying the inevitable.
