How many oxygen sensors does a Nissan Cube have?
Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more.
How do you remove an O2 sensor from a car?
In order to do so, rotate the oxygen sensor counterclockwise. Utilize a removal tool at this point. Plug in the dummy oxygen/o2 sensor by rotating it clockwise. Insert it into the exhaust system and connect it to the electrical wiring. You can now lower the car onto the ground, but wait, we’re not done yet!
What do you mean by downstream or before Cat O2 sensors?
He means the downstream or after cat o2 sensors. I have mine removed and tuned out. There are no negative side affects as these sensors only monitor the efficiency of the catalyst. Your upstream or before cat o2 sensors are what determines if you are running the proper air/fuel ratio.
What happens if I remove the exhaust sensor?
Without them the EFI goes into limp mode and fuel mileage goes out the window. He means the downstream or after cat o2 sensors. I have mine removed and tuned out. There are no negative side affects as these sensors only monitor the efficiency of the catalyst.
Where is the O2 sensor in a manifold?
You will likely find one sensor in each manifold and down tube. The O2 sensor looks like a white spark plug and has a green wire extending out of the top of it. Follow the green wire from the O2 sensor, and locate the wiring harness that connects to it. Unplug the O2 sensor from the wiring harness, and tie the green wire into a loop.
What are the downstream O2 sensors on a Nissan?
One or two sensors will be downstream, B1S2 and B2S2. The procedure is similar for the downstream O2 sensors (Bank 1 & 2, Sensor 2). For the downstream sensors, you will find it easier to access the O2 sensor from underneath the car.
Where can I find a dummy O2 sensor?
You will need to locate the dummy O2 sensor from an aftermarket supplier for your vehicle on the Internet or a mechanic that specializes in aftermarket racing or performance parts. For specific information about your vehicle’s O2 sensor and emissions control system, consult the particular vehicle’s manual (see Resources).
Is there a way to bypass the rear O2 sensor?
By replacing the real O2 sensor with a dummy O2 sensor, your vehicle’s engine control unit will be fooled by the sensor and will not generate any error codes for the vehicle’s emissions control system. Lower the vehicle to the ground. Dummy O2 sensors are used for tuning vehicles that will not be used on public roads.
How do you remove the oxygen sensor from a Nissan?
The downstream oxygen Bank 1 Sensor 2 sensor has to be accessed from underneath the engine. You will need to remove the bottom splash shield. Disconnect the oxygen sensor electrical connectors. Press the connector and pull it away to unplug it from the oxygen sensor. Use an oxygen sensor wrench to remove the oxygen sensor.
