Oxygen Sensor Schematic

Bank 1 is the bank of cylinders that houses cylinders 1 2 3 and 4. By looking at a wiring diagram here provided by in chrysler vehicles four wire oxygen sensor heater circuits tend to be water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow which is a very common problem for this type codes. This sensor measures the amount of unburned oxygen that is present in the oxygen as it exits the vehicle which is indicative of the fuel mixture.

A wiring diagram is a streamlined standard pictorial depiction of an electrical circuit.

Oxygen sensor schematic. It reveals the components of the circuit as streamlined forms and also the power as well as signal links between the tools. It was developed by robert bosch gmbh during the late 1960s under the supervision of dr. An oxygen sensor or lambda sensor where lambda refers to air fuel equivalence ratio usually denoted by λ is an electronic device that measures the proportion of oxygen o 2 in the gas or liquid being analysed. The original sensing element is made with a thimble shaped zirconia.

Figures 5 and 6. The four wire universal oxygen sensor must be changed approximately every 60 000 miles and requires a specific wiring process. The right front oxygen sensor is also known as. Wellborn variety of 4 wire oxygen sensor wiring diagram.

If the wiring schematic shows the o 2 sensor heater circuit is ground controlled through the computer start looking for a short to ground on the sensor s negative control wire. August 18 2018 by larry a. One quick test is to disconnect the computer from the circuit. The right front oxygen sensor is located on bank 1 and before the catalytic converter.

Bank 1 is located on the passenger side of the engine compartment.
