RB20DET Oxygen Sensor (O2 Sensor) Replacement Part Number
Oxygen sensors (also known as o2 sensors) are a common wear and tear item in the RB20DET that any new owner of a Skyline will need to replace at some point. There are also issues with melting if the plugs or wires get close to aftermarket headers after a careless install.
The parts for replacement are linked below:
It’s a standard Bosch sensor for the RB20DET that also fits some other applications such as the SR20DET. In general, Nissan used the same sensors for their 90s cars. Note that the plug in the image is NOT the same plug as the RB20DET uses, but the sensor you will receive IS the correct sensor. We have ordered over 15 of these sensors and used them with no issues.
Removing o2 sensors is sometimes difficult to do, given that you can’t easily get a socket on it due to the wires extending from the top. If that’s the case, and you can’t reach it with a wrench, use of these O2 Sensor Sockets to remove it.
A regular set of crows feet also works and they have more applications than just O2 sensors.
The oxygen sensor is located in the downpipe.
