NO, If your vehicle utilizes electronic engine controls (It wouldn't have O2 sensors if it didn't), these are necessary for the ECM to adjust the air/fuel ratio. Without them, the engine won't run properly, fuel mileage will suffer, emissions will be uncontrolled, and the vehicle will fail emission testing.
Do O2 sensor spacers really work?
How does an O2 Spacer work? O2 spacer extends the gap between the o2 sensor and the exhaust gases, with an increased gap, it will provide a lower Co2 reading. However, 90% of the time they will work provided the original o2 sensor is not faulty.
How does an O2 sensor affect performance?
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.2 Mar 2020
What happens if you unplug 02 sensors?
With the O2 sensor removed, your ECU can no longer calculate how much fuel should be injected. The ECU will fallback to its default value and always inject the same amount of fuel every time. This could cause either low performance or horrible fuel economy.31 Jul 2020
What is a dummy O2 sensor?
A dummy O2 sensor is a fake one that does readings like a normal one. A dummy one sends the cars computer the proper information that a normal one would send if it were reading correctly. Dummy O2 sensors are easy to use. All you have to do is locate your cars current O2 sensor and unplug it.
Can you drive with O2 sensor unplugged?
With a bad or unplugged O2 sensor, the engine will operate in open loop mode, so chances are it will run a little rich and mileage will go down.24 Jan 2010
Is there a way to bypass O2 sensors?
Bypassing an oxygen sensor--also called an O2 sensor--can only be done using a dummy O2 sensor. Oxygen sensors are part of the vehicle's emissions control system and it may or may not be legal to replace the O2 sensor with a dummy sensor.

What happens if you remove downstream O2 sensor?
With the O2 sensor removed, your ECU can no longer calculate how much fuel should be injected. The ECU will fallback to its default value and always inject the same amount of fuel every time. This could cause either low performance or horrible fuel economy.31 Jul 2020
Can you run a car without downstream O2 sensor?
yes. The rear O2 sensors are emissions related only. You will have an error light but it won't harm anything. If you happen to need to get an emission test, you will fail..16 Dec 2017
