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. To diagnose the fault, a code reader or scan tool is connected to the vehicle to read the trouble code.


Life Expectancy of an Oxygen Sensor 30, to 50, miles is typical. And that is under normal operating conditions! Bank 1, containing cylinder 7, is always the most forward cylinder on the block.

Access the current Walker Commercial Vehicle exhaust parts catalog. The scan tools can vary in the display of information shown. 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 wakler.


This coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.

Items in search results. On many older pre vehicles, a trouble code catqlog 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.

Click here to diagnose types of oxygen sensor contamination. Heated sensors can also be located further downstream exhaut to the catalytic converter which increases their life expectancy. Sometimes contaminants such as coolant, oil or silicone particulates will find their way to the sensor as well.

Most installers will probably not be able to spot an oxygen sensor problem until it is too late wwalker the catalytic converter is already well on its way to failure. The trouble code itself does not tell you which part to replace! Heated oxygen sensors have a built-in heater which heats the sensors. Condition see all Condition.

These contaminate the sensor and render it inoperable. A bad oxygen sensor can cause unacceptable emissions levels, affect performance and ultimately damage the catalytic converter. The walksr of the engine will have the accessory pulleys and drive belts, regardless of orientation in the engine compartment.

The air-fuel mixture is thus always moving from rich to lean averaging very close to stoichiometric ideal ratios.

Where are my oxygen sensors located? Heated oxygen sensors should be checked or replaced every 60, tomiles. Whether by contamination or normal use, its effectiveness will inevitably decrease over time. Amounts shown in italicized text are for items listed in currency other than Canadian dollars and are approximate conversions to Canadian dollars based upon Bloomberg’s conversion rates.

You’ll receive email and Feed alerts when new items arrive. Much less exhaust gas needs to contact the ceramic element, making these sensors less prone to contamination. Failures wapker occur instantaneously at the time the contaminant contacts the oxygen sensor, causing a dead sensor, or gradually over a period of time. View Part Image Search.
