CUMMINS OXY SENSOR 4326874

$ 425

 Cummins oxy sensor 4326874 takes note of the oxygen in your truck exhaust stream, to make sure that it is within the prescribed limit and check the functioning of the catalytic converter properly. 4326874 Cummins oxy sensor diagnosis the trucks air /fuel mixture by oxidizing a portion of the oxygen that

Goes through the exhaust system. The output is then converted into an electric signal and passed back to the engine control computer, which calculated the input and then changes its settings for fuel metering and timing to have an ideal mixture. This mechanism is an ongoing mechanism that constantly changes depending upon the load on the engine.

HOW LONG DO TRUCK CUMMINS OXY SENSORS LAST?

Heat is the major factor the affects the longevity of Cummins oxy sensor. There are other factors as well that contribute to its excessive amount of unburnt oil, contaminants in the exhaust, and other things. On average the Cummins oxygen sensor should last between 50,000 and 60,000 miles. However, maintenance of the engine plays a big role as well, in case the engine is properly maintained Cummins oxygen cylinder would last much longer. On the other hand, in case the engine in bad shape, the oxygen sensor Cummins could fail prematurely and will have to be replaced.

HOW DO I KNOW IF MY TRUCK CUMMINS OXYGEN SENSOR IS GOING BAD?

The only tested way for doing it is by using a diagnostic code reader. However, you could look for some other symptoms as well.

• Check engine light would come on, due to Cummins oxy sensor catching a trouble code with truck engine computer.
• Reduction in the performance and mileage of the truck.
• Not ideal performance even after replacing plug wires and spark plugs.
• Black emission smoke and carbon deposit around the tailpipe.

WHAT CAN CAUSE  A HEAVY-DUTY TRUCK OXYGEN SENSOR TO FAIL?

• A fuel that is contaminated.
• In case the engine is burning too much oil, herby leaving the carbon residue on the sensor.
• External factors such as salt on the road, chemicals, gasket material, undercoating material.
• The service life cycle of the sensor has come to an end.
