This rear oxygen sensor, also known as a lambda sensor, is fitted to the exhaust system after the catalytic converter. It is a crucial component of your vehicle's emissions control system, responsible for measuring the amount of oxygen remaining in the exhaust gases after they have passed through the converter.
This information is sent to the engine control unit (ECU) to monitor the efficiency of the catalytic converter. A faulty rear oxygen sensor can trigger a check engine light, cause your vehicle to fail an emissions test, and in some cases, lead to reduced fuel economy as the ECU can no longer accurately verify the performance of the emissions system.
There are 2 required per vehicle, there is one each side / exhaust manifold and they are the same as each other.
SOLD INDIVIDUALLY.
These are often diagnosed in code as sensor 2 = rear sensor.

Likewise bank 2 sensor 2 = LH exhaust manifold rear oxygen sensor.
