Are aftermarket O2 sensors as good as OEM?

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. via

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. via

Can I run my car without O2 sensor?

Driving with a faulty O2 sensor means the computer won't be getting the correct reading of the mixture and hence it won't be able to adjust the air-fuel mixture properly. But if your engine starts and runs, and can stay running, it's drivable. via

Are Bank 1 and Bank 2 sensors interchangeable?

In most cars, they are exactly the same between banks 1 & 2. In fact in a lot of cars, you could use the down stream sensors as the upstream sensors (this all assumes OBD2). So, yes, order exact for both sides. via

How does a 5 wire O2 sensor work?

  • • 1st wire = signal voltage.
  • • 2nd wire = isolates the ground of the signal to reduce signal noise.
  • • 3rd and 4th wires = heating element so the sensor starts operating faster and more reliably***
  • • 5th wire = detects by how much the air-fuel ratio is too rich or lean.

    Should O2 sensors be replaced in pairs?

    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. However, on most vehicles produced since 1996, replacing one sensor (especially the front engine monitoring sensor) will cause the ECU to set a code for the other sensors. via

    What are the two white wires on a oxygen sensor?

    White wires are for the heater - the heater is not polarity sensitive, it's just a resistive element. The black wire is the sensor output. The gray wire is the sensor return, or ground. Back in the day (old fart mode ON) o2 sensors had simply one output wire and were grounded through the sensor body. via

    Why does my oxygen sensor keep failing?

    Why do O2 sensors fail? Since the oxygen sensor is in the exhaust stream, it can become contaminated. Common sources of contamination include an excessively rich fuel mixture condition or oil blow-by in an older engine and engine coolant being burnt in the combustion chamber as a result of an engine gasket leak. via
