6 OXYGEN SENSORS... Walker Oxygen Sensors are precision made for outstanding performance and manufactured to meet and exceed all original equipment specification and test requirements. 100% OEM QUALITY 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 (<150mV lean & > 750mV 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 Products, Inc. 2014

7 TECHNICAL RECOMMENDATIONS 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 leads to the sensor becoming oil-fouled. Also, a small amount of tetra-ethyl lead in the gasoline can kill an oxygen sensor. Over-thecounter fuel additives, which are not oxygen sensor safe can also kill an oxygen sensor. Failures can occur either 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% and cause 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-ohmmeter. 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. PREVENTATIVE MAINTENANCE One-wire and two-wire unheated type oxygen sensors should be checked or replaced every 30,000 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 type 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 type sensors can also be located further downstream (closer to the catalytic converter) which increases their life expectancy. Heated type oxygen sensors should be checked or replaced every 60,000 miles. Walker Products, Inc. 2014

8 WHAT IS THE LIFE EXPECTANCY OF AN OXYGEN SENSOR? The life expectancy of an oxygen sensor is approximately 30,000 miles for unheated sensors and 60,000 miles for heated sensors. Even under normal operating conditions, oxygen sensors must endure a constant barrage of harmful exhaust gases, extreme heat and high velocity particulates. Longevity of oxygen sensors in older vehicles may be reduced due to worn piston rings and valves. Sometimes oxygen sensors can become contaminated by coolant, oil or silicone particulates. Oxygen sensors exposed to these contaminates will not operate as designed. Although sensors in some applications can remain serviceable up to 90,000 miles, the effectiveness of oxygen sensors 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 oxygen sensors at each tune-up and replace faulty sensors with a new Walker oxygen sensor.

9 DIAGNOSTIC TROUBLE CODES DTC Codes When oxygen sensor failure occurs, a DTC (Diagnostic Trouble Code) is recorded in the ECU (Engine Control Unit) and a MIL (Malfunction Indicator Lamp) 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 OBDII 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. When using a list of DTC trouble codes and you have identified the description, 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 BY 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 = 1, B2 = 2. When applying OBD II to oxygen sensors, the codes would then read B1S1. This refers to 1, Sensor 1. Finding 1 is not difficult. The front of the engine will have the accessory pulleys and drive belts, regardless of orientation in the engine compartment. 1, containing cylinder #1, is always the most forward cylinder on the block. There will be a visible difference in the cylinder head location. Refer to the diagrams below. Sensor 1 will be the upstream position and Sensor 2 would typically be the downstream position. In some instances, Sensor 2 can be upstream making Sensor 3 downstream. TYPICAL ENGINE BANK IDENTIFICATION: Walker Products, Inc. 2014
