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

A slow sensor can only be diagnosed by using a digital oscilloscope or scope meter. View Part Image Search. Sometimes contaminants such as coolant, oil or silicone particulates will find their way to the sensor as well. 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.

Sensor 1 will be the pre catalytic position and Sensor 2 would typically be the post catalytic position. Whether by contamination or normal use, its effectiveness will inevitably decrease over time. Save walker exhaust catalog to get e-mail alerts and updates on your eBay Feed.

As a leading supplier to global vehicle manufacturers, Walker is committed to providing the right parts to deliver OE-style fit, sound and performance for every application. These sensors rely solely on hot exhaust gas to heat up to operating temperature and are designed exuaust allow a large volume of exhaust gas to make contact with the active ceramic element.

Use this tool to quickly locate clamps by size and style. The scan tools can vary in the display of information shown.

These contaminate the sensor and render it inoperable. Rep Portal Login Call Us: There will be a visible difference in the cylinder head location. Finding Bank 1 is not difficult. This coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases.

Use this tool to quickly wwlker universal elbows by size and style. This refers to Bank 1 Sensor 1. 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. In addition, a porous ceramic coating has been applied to the side exposed to the exhaust gas. Click here to diagnose types of oxygen sensor contamination. This can lead to premature failure of the catalytic converter.

Located in the exhaust system, the oxygen sensor cataog a voltage proportional to the amount of oxygen in the exhaust versus the air mV rich. In an effort to provide you with up-to-date information, please refer to this section exhauet the newest coverage available.

Oxygen Sensors

Failures can occur instantaneously at the time the contaminant contacts the oxygen sensor, causing a dead sensor, or gradually over a period of time. The front of the engine will have the accessory pulleys and drive belts, regardless of orientation in walkker engine compartment. A dead sensor can be detected with a relatively inexpensive digital volt-ohm meter.

The ceramic sensor body is contained in a housing which protects it against mechanical effects and facilitates mounting. To find the right Walker replacement part using any OE or competitive part number, the Walker Commercial Vehicle Interchange database provides a convenient online interchange tool.

Gradual deterioration results in a slow sensor which does not react as quickly as it should, causing the catalytic converter to perform less efficiently.

Heated oxygen sensors should be checked or replaced every 60, tomiles.
