A wideband oxygen sensor (commonly referred to as a wideband O2 sensor
Oxygen sensor
An oxygen sensor (or lambda sensor) is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. It was developed by the Robert Bosch GmbH company during the late 1960s under the supervision of Dr. Günter Bauman.
How many volts does a wideband O2 sensor produce?
It increases or decreases in proportion to the relative richness or leanness of the air/fuel ratio. With a stoichiometric air/fuel ratio of 14.7:1, the wide-band O2 sensor will produce a steady 0.450 volts.
How do I know if my O2 sensor is bad?
If you want to know how to tell which O2 sensor is bad, it is also synonymous with wanting to know if it is the upstream or downstream oxygen sensor that is going bad. You will be able to tell with the check engine light coming on and the code will read bank 1 sensor 1 or 2 or bank 2 sensor 1 or 2.
How fast does the wide band oxygen sensor respond to changes?
The wide band oxygen sensor responds to changes in the air/fuel mixture in less than 100 milliseconds. The Precision Wideband Controller circuit is intended to be used to directly control the fuel mixture, so it needs to be accurate and repeatable.
How do O2 sensors work?
O2 sensors are installed in the exhaust and were created to measure oxygen levels within the exhaust. They do this by allowing outside air to come into the sensor that is then heated to charge the ions to create voltage.
Which o2 sensor is wideband?
The wideband oxygen sensor is sometimes referred to as a lambda sensor or UEGO. It is the ideal sensor to be used with all PLX Wideband Controllers.

What's the difference between a wideband and narrowband o2 sensor?
A wideband o2 sensor gives you the data you and your ECU need to be able to tune that properly. While a narrowband can only tell you when it's 14.7:1, and is therefore nearly useless for tuning for anything other than a steady cruise condition.
Is a wideband the same as o2 sensor?
A wideband oxygen sensor (commonly referred to as a wideband O2 sensor) is a sensor that measures the ratio of oxygen to fuel vapor in the exhaust exiting an engine. The measured ratio is expressed as parts of oxygen to fuel.
Can I use the same O2 sensor for upstream and downstream?
They both function the same but are different enough that they cannot be swapped. If you need assistance having this checked or repaired, a qualified pro from YourMechanic can come to your location to inspect the system and replace any O2 sensors that are faulty.
Is Bank 2 upstream or downstream?
DownstreamBank 2 Sensor 2 means Downstream Left/Front.
Do you need a wideband to tune?
If you plan to head to the rollers to get it setup, and want a more hands-off install, then no need for a wideband at all. The dyno operator will use their own wideband during mapping, will optimise the fuelling and ignition, and, everything being equal, it should never change once tuned.
Why do I need a wideband O2?
Wideband O2 sensors monitor the amount of oxygen in the exhaust to measure the Air Fuel Ratio, or AFR. The AFR tells your tuner whether the car requires more or less fuel to achieve the best power or economy, and allows your tuner to keep the engine safe.
Is narrowband or wideband better?
Narrowband systems typically have lower data rate transmissions, whereas wideband systems support relatively higher data rate transmissions. To put simply, wideband systems allow for faster communication.

How many wires does a wideband o2 sensor have?
If It Is 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.
What is a wideband O2 sensor?
For engine calibration purposes, diagnostic purposes, datalogging and performance work a wideband O2 sensor is the correct tool for the job. For emissions related purposes used in conjunction with catalytic converters a narrowband O2 sensor is essential (normally with a wideband O2 sensor in place as well for the full power engine calibration).
Can wideband controllers work with Haltech ECU?
The added benefit of using the new CAN wideband controller with your Haltech ECU diagnostic information about the sensor is now being broadcast out to the ECU. This additional diagnostic information is used by the ECU to determine if the sensor is up to correct operating temperature, if the sensor has a short or fault condition or if the sensor is has become disconnected. In any of these circumstances the ECU will automatically turn off closed loop O2 control (if its enabled) and run in open loop mode.
Why is my wideband oxygen sensor only designed to read the oxygen content of the exhaust gases?
Because the stoich AFR mixture changes with the type of fuel being used , many people become confused when their wideband gauge displays the wrong AFR targets for their fuel choice. This is because your wideband oxygen sensor is only designed to read the oxygen content of the exhaust gases and doesn’t care what fuel is being used.
What scale is wideband gauge?
Left: Wideband gauge displaying a stoich AFR in its converted gasoline scaling. Right: Wideband displaying a stoich reading in its native lambda scale. There are some enthusiasts that will over react under certain driving conditions because they don’t know how to interpret what their wideband gauge is telling them.
What is AFR gauge?
Many enthusiasts have a wideband oxygen sensor and air/fuel ratio (AFR) gauge installed at the recommendation of their tuner or friends (if not already factory equipped), but don’t fully understand how to interpret the readings or what the target value should be under various conditions. Reading a wideband gauge is important for power hungry ...
What is a wideband exhaust gas sensor?
The wideband exhaust gas oxygen sensor comes in many constructional forms, but are basically similar in nature. They consist of two parts: a Nernst reference cell and an oxygen pump cell, co-existing in a package that contains a reference chamber and heater element (used to regulate the temperature of the Nernst/pump).
What does the Nernst cell sense?
The Nernst cell senses exhaust gas oxygen in the same as a conventional narrow band O 2 sensor. If there is a difference in oxygen levels across the ZrO 2 sensor element, current flows from one side to the other and produces a voltage.
Does a wide band sesnor measure temperature?
The wide band sesnor does not have any form of direct temperature measurement (i.e. thermistor,thermocouple, etc.). However, monitoring the resistance of the reference cell yields a close representation of the probe temperature – the resistance of the reference cell varies with temperature.
What does a narrowband sensor know?
Narrowband sensors only know three things: lean, rich and stoich. Depending on the oxygen content it reads in the exhaust it sends a signal between 0 and 1 volt. 0 means too lean and 1 means too rich.
What does more oxygen mean on a bike?
More oxygen means it’s running lean and less oxygen means it’s running rich. What fuel tuners do is offset the ECU signals to change the ratio to make more power or to create adjustments based on new bike modifications. Narrowband sensors only know three things: lean, rich and stoich.
What do you need to know about tuning a car?
These will help you be able to tune more accurately or simply understand what a professional tuner has done for you. These will also help you understand the difference between narrowband and wideband O2 sensors.
How to tell if O2 sensor is bad?

You will be able to tell with the check engine light coming on and the code will read bank 1 sensor 1 or 2 or bank 2 sensor 1 or 2. Bank 1 is the exhaust on the motor's side with ...
What happens if the O2 sensor does not measure oxygen?
If the O2 sensor does not precisely measure the oxygen level, the ECU will be unable to adjust the fuel/oxygen levels. Based on the oxygen level read by the O2 sensor, the ECU will change the amount of gasoline entering the system. It is critical to note that if the fuel and oxygen combination is improper, the quantity of pollutants emitted by your ...
How long does an oxygen sensor last?
Most oxygen sensors have a lifespan of 30,000 to 50,000 miles, or 3-5 years, with newer sensors lasting much longer with adequate maintenance and care.
What is the purpose of an O2 sensor?
It has a tip sensor and its purpose is to determine the proportion of oxygen in the exhaust gases. When the O2 sensor is working properly, it ensures that your engine maintains top performance and that emissions are kept under control.
What does it mean when your A/F ratio is swinging?
A swing in the A/F ratio indicates that an upstream or control sensor is malfunctioning. There are also other signs that the upstream or downstream oxygen sensor is bad.
How many O2 sensors are there in a 1996 V6?
Most V6 and V8 engines built after 1996 include at least two upstream O2 sensors and one or two downstream O2 sensors. Some engines can have up to six O2 sensors. An O2 sensor error code will show the sensor location by sensor number (1, 2, 3, or 4) and cylinder bank (1 or 2).
How much does it cost to replace an O2 sensor?
That component will cost you between $500 and $1000 to replace.
