Can I replace O2 sensor with wideband?
You will need to find a wideband controller with a 0 to 1 V narrowband output. This emulated output shoule work. The only thing is you will need to rewire some things to do it – I think it’s wore trouble than it’s worth. It may be a better idea to weld in a second bung.
What do you need to know about wideband O2 sensors?
A wideband O2 sensor has an output from 0-5V, a big part of the whole “wideband” thing. This means that AFR (air/fuel ratio) values are spread over a wider voltage range, giving much higher resolution than a 0-1V sensor. The bigger part of the wideband thing is the actual range of AFR’s that a wideband is accurate over.
What do cars have factory wideband O2’s?
Any wideband o2 requires a controller. They are a 2 component system, a pump, and a narrowband sensor. The controller controls the pump, and compares the pump, and narrowband to come up with a lambda reading. Loading… We cant just wire a wbo2 into our ecu’s like he has stated. People do make there own wbo2’s like the JAW wbo2 I think its called.
What are the wires in an oxygen sensor?
Narrowband sensors have four wires going to them: +5V, a heater/ground circuit consisting of two wires, and a signal wire. The signal wire supplies the ECU with a 0-1V signal. Factory oxygen sensors have improved dramatically over the years, and are much more “wideband” than before, but they still aren’t wideband sensors.
What are the voltages on a wideband sensor?
If your sensor is a wideband sensor, there will be TWO SIGNAL WIRES – these are called the “Current Pump” wires. The voltages on these current pump wires varies from manufacturer to manufacturer. Toyotas have 3.0 volts on their reference wire and the 3.3 volts on the current return wire.
How does a wide band oxygen sensor work?
The problem is that the sensor has four wires (just like most others), but it’s actually a Wide Band Oxygen Sensor or Air Fuel Ratio (AFR) Sensor. These types of sensor have been in use for many years and are very reliable, which is just as well, because their diagnosis is a far cry from that of a conventional O2 sensor. So how does it work?

Why does my oxygen sensor give the same reading?
The new sensor gave the same reading, so he contacted Blue Print for some help and advice. The problem is that the sensor has four wires (just like most others), but it’s actually a Wide Band Oxygen Sensor or Air Fuel Ratio (AFR) Sensor.
