What does a 4 wire universal oxygen sensor do?

Automotive engines are composed of a complex set of systems that are monitored by several types of sensors. The four-wire universal oxygen sensor is one of the sensors that monitors fuel consumption. 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.

How much does a universal O2 sensor cost?

It takes three O2 sensors — two before and one after the catalytic converter. They’re all the four-wire type. The car has 165,000 miles already so the less money spent the better. Surfing the ‘net suggests I have two options — go with OEM-style sensors for about $100 each, or “universal” 4-wire sensors for under $50.

What are the colors of the oxygen sensor?

How often does a universal oxygen sensor need to be changed?

The four-wire universal oxygen sensor must be changed approximately every 60,000 miles and requires a specific wiring process. Install the four-wire universal oxygen sensor. Cut the original wire connector exposing the copper ends of the wires.

How is the O2 sensor connected to the ECM?

https://play.google.com/store/apps/de… The O2 or Oxygen sensor is in charge of measuring the content of the exhaust. Learn about the O2 sensor electrical connection and how it relates to the ECM and signal output. Presented here to help you understand the O2 sensor from an electronics and wiring diagram point of view.

How do you install a universal fit sensor?

Cut the new Sensor wires to length. IMPORTANT: The new Sensor with the old connector must be the same length as the old Sensor and connector originally. 2. Cut the old Sensor wire to length. 3. Strip the wire ends to a length of 7mm. 4. Crimp the butt-splices with a ratchet crimping tool with red die (size 22 – 16). 5.
