Oxygen Sensor by Walker Products

Oxygen Sensors (O2)

Loading...

Descriptions
The oxygen sensor is a device which determines the oxygen content of the exhaust gas. Since the amount of oxygen in the exhaust gas is a very good indicator of combustion efficiency, it is also the best place to monitor the air fuel ratio. Located in the exhaust system, the oxygen sensor produces a voltage proportional to the amount of oxygen in the exhaust versus the air (<150 mV lean & >750 mV rich). This data is used to control the air-fuel mixture through PORT or TFI injectors and carburetors. Sensors are monitored or checked anywhere from 4 to 100 times per second. The air-fuel mixture is thus always moving from rich to lean averaging very close to stoichiometric (ideal) ratios. The ceramic sensor body is contained in a housing which protects it against mechanical effects and facilitates mounting. The ceramic body is made of stabilized zirconium dioxide (zirconia). Its surfaces are coated with electrodes made of a gas-permeable platinum layer. In addition, a porous ceramic coating has been applied to the side exposed to the exhaust gas. This coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.
Walker Oxygen Sensors are precision made for outstanding performance and manufactured to meet and exceed all original equipment specification and test requirements.

Malfunctioning and Failed Sensors
Oxygen sensors can fail when the sensor's ceramic element is exposed to certain types of silicone compounds or when an oil-burning engine adds to the sensor becoming oil-fouled. Small amounts of tetra-ethyl lead in the gasoline or over-the-counter fuel additives, which are not "oxygen sensor safe", can also kill an oxygen sensor. Failures can occur instantaneously at the time the contaminant contacts the oxygen sensor, causing a dead sensor, or gradually over a period of time. Gradual deterioration results in a slow sensor which does not react as quickly as it should, causing the catalytic converter to perform less efficiently. This can lead to premature failure of the catalytic converter. Slow oxygen sensors can cause a drop in fuel economy of 10-15%, excessive exhaust emissions and poor drivability. Unfortunately, the symptoms of a slow oxygen sensor are not always obvious to the vehicle owner unless the vehicle fails an emissions test, a decline in fuel economy is noticed or drivability problems occur. A dead sensor can be detected with a relatively inexpensive digital volt-ohm meter. A slow sensor can only be diagnosed by using a digital oscilloscope or scope meter. Most installers will probably not be able to spot an oxygen sensor problem until it is too late and the catalytic converter is already well on its way to failure.
Preventive Maintenance
One-wire and two-wire unheated oxygen sensors should be checked or replaced every 30,000 to 50,000 miles. These sensors rely solely on hot exhaust gas to heat up to operating temperature and are designed to allow a large volume of exhaust gas to make contact with the active ceramic element. These sensors are exposed to contamination, especially the "wide-slot" varieties found on Chrysler, Ford and General Motors vehicles. Heated oxygen sensors have a built-in heater which heats the sensors. Much less exhaust gas needs to contact the ceramic element, making these sensors less prone to contamination. Heated sensors can also be located further downstream (closer to the catalytic converter) which increases their life expectancy. Heated oxygen sensors should be checked or replaced every 60,000 to 100,000 miles.
Diagnostic Trouble Codes (DTC)
When oxygen sensor failure occurs, a DTC is recorded in the Engine Control Unit (ECU) and a Malfunction Indicator Lamp (MIL) is illuminated on the dash, alerting the driver the vehicle has a problem. To diagnose the fault, a code reader or scan tool is connected to the vehicle to read the trouble code. The scan tools can vary in the display of information shown. Some show a definition for the code while others show only a trouble code number. There are generic or standard OBD II codes and vehicle manufacturers use additional codes called enhanced or OEM-specific codes. On many older (pre 1995) vehicles, a trouble code or DTC can be read without a scan tool or code reader by using a manual flash code procedure. After having identified the description using a list of DTC trouble codes, the next step is to diagnose the fault. You must follow the diagnostic procedure to properly diagnose the system, sensor and/or circuit. The trouble code itself does not tell you which part to replace! The scan tools or code readers speak OBD II language, meaning the references to the engine are coded.
* B1 = Bank 1
* B2 = Bank 2
When applying OBD II to oxygen sensors, the codes would then read B1S1. This refers to Bank 1 Sensor 1.Finding Bank 1 is not difficult. The front of the engine will have the accessory pulleys and drive belts, regardless of orientation in the engine compartment. Bank 1, containing cylinder #7, is always the most forward cylinder on the block. There will be a visible difference in the cylinder head location. Sensor 1 will be the pre catalytic position and Sensor 2 would typically be the post catalytic position. In some instances, Sensor 2 can be pre catalytic thus making Sensor 3 post catalytic.
Life Expectancy of an Oxygen Sensor
30,000 to 50,000 miles is typical. However, constantly exposed to the harsh environment found in an automobile's exhaust system, the oxygen sensor sustains a constant barrage of harmful exhaust gases, extreme heat and high velocity particulates. And that is under normal operating conditions! Sometimes contaminants such as coolant, oil or silicone particulates will find their way to the sensor as well. These contaminate the sensor and render it inoperable. An oxygen sensors life is long, in some applications up to 100,000 miles. Whether by contamination or normal use, its effectiveness will inevitably decrease over time. At Walker Products, we recognize the need to keep vehicles running clean. A bad oxygen sensor can cause unacceptable emissions levels, affect performance and ultimately damage the catalytic converter. Make it a point to check the oxygen sensors at each tune-up and replace faulty sensors with new Walker oxygen sensors.

CATALYTIC CONVERTERS

CATALYTIC CONVERTERS

Walker offers quality direct-fit and universal converters that comply with EPA and CARB requirements.
The catalytic converter is designed to convert harmful emissions, produced by an internal combustion engine, to less-harmful elements: H2O (Water), CO2 (Carbon Dioxide) and N2 (Nitrogen). To perform this conversion, the catalytic converter works with a vehicle's PCM (Powertrain Control Module) and other emissions control devices.
OBDII (On-Board Diagnostics Version 2) monitors the emissions control devices and provides feedback on their operating condition.
As the EPA (Environmental Protection Agency) updates emissions standards, the OBDII system becomes more sensitive to fluctuations in emissions performance.

two way Catalytic Converter

Loading...
* Allows oxidation of CO (Carbon Monoxide) to less-harmful CO2 (Carbon Dioxide)
* Allows oxidation of HC (Unburned Hydrocarbons) to CO2 (Carbon Dioxide) and H2O (Water)

In this design, exhaust gases are directed to flow through the substrate containing precious metals platinum and palladium, which allow the chemical reaction to occur. The exhaust gases increase in temperature as the conversion process takes place.
Because of the intense heat created by this process, exhaust gases leaving the converter should be hotter than the gases entering the converter. This also explains why heat shields are required on most units.
Two-way converters operate relatively efficiently with a lean fuel mixture. Ineffectiveness in controlling NOx led to the introduction of three-way converters.

THREE-WAY CATALYTIC CONVERTERS

Loading...
* Allows reduction of NOx (Nitrogen Oxides) to N2 (Nitrogen) and O2 (Oxygen)
* Allows oxidation of CO (Carbon Monoxide) to less-harmful CO2 (Carbon Dioxide)
* Allows oxidation of HC (Unburned Hydrocarbons) to CO2 (Carbon Dioxide) and H2O (Water)
Three-way converters have been used in vehicle emissions control systems in North America - and many other countries - since 1981.
The three-way without air uses advanced catalyst chemistry to store and release O2, in conjunction with an O2 monitoring and control system.
This system utilizes one or more O2 sensors to oscillate the fuel mixture between lean and rich conditions. This oscillation, combined with the O2 storage and release on the catalyst surface, allows for optimum reduction of all three emissions.
Three-way converters are used in conjunction with OBDII diagnostic systems on today's vehicles. This system alerts the driver when the converter is not working at peak efficiency.

Walker air gap pipe, is double walled pipe with an "air gap" between layers of pipe to promote insulation and allow faster converter light-off, for reduced emissions. Walker incorporates air gap pipe into designs where the OE uses that technology (or a full 360° heat shield), and also where the front pipe is integral part of the converter assembly. Using air gap pipe also assures that there are no jagged edges and no possibility of the heat shield weld coming loose to cause noise.
