The O2 sensor in a van is instantly an integral atom of the exhaust transaction.The oxygen sensors are located directly in the exhaust system, normally by portholes that the sensor screws into on the exhaust pipes--and in some cases, on the exhaust manifold. The exterior group of the sensor provides a wire and plug that plugs the harness into the ECU and transmits the voltage for monitoring.
History
Designed in the 1960s by a Robert Bosch, the oxygen sensor in a van make-believe its front introduction in the overdue 1970s on a Volvo that extremely introduced the 3-way-catalyst manner.
Although it has been on all sides of for many years--since the implementation of On-Board-Diagnostics II in 1996--the vastness of O2 sensors per vehivle has doubled. Finding them for replacement is like now even trickier.
Location
By 1981, to diminish emissions, all vehicles were continuance manufactured with catalytic converters.
Function
The service of the O2 sensor (and avowed as the Lambda sensor) is to scanner the vastness of fuel-to-air combine in the combustible engine of a vehicle. The sensor transmits voltage and the engine administration pc (ECU) monitors the ratio. There is an paragon ratio--when a sensor fails or there is an internal botheration with the engine, more pollutants emit from the exhaust.
Types
The older sensors were "unheated" sensors. Since they do not transmit voltage until their internal temperature reaches 600 degrees Fahrenheit or more, this allows a period of time in between the ECU being able to monitor the sensor. "Heated" sensors are common today, have extra wires for the heating element and assist in heating the sensor more rapidly.
Considerations
If replacing an oxygen sensor, a direct-fit replacement is far superior to the "universal" sensor which would require cutting, identifying and splicing the wires of the sensor. The direct-fit sensor provides the necessary wires and plug to fit the plug of the wire harness easily.
