What is the purpose of a front O2 sensor?
The Purpose of a Front O2 Sensor. Front O2 sensors analyze the exhaust coming directly from the engine. When O2 sensors were installed only in one place, they were located in the position that made them what would be called front O2 sensors today.
Where are Bank 1 and 2 O2 sensors located?
Summary. If your DTC code says: Bank 1 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #1. Bank 1 Sensor 2 = O2 sensor located after the catalytic converter, on the side with Cylinder #1. Bank 2 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #2.
Where is the O2 sensor on a catalytic converter?
Bank 1 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #1. Bank 1 Sensor 2 = O2 sensor located after catalytic converter, on the side with Cylinder #1. Bank 2 Sensor 1 = O2 sensor located before the catalytic converter, on the side with Cylinder #2.
Where are the o2sensors located in the exhaust system?
There are different locations in the exhaust system where O2sensors are positioned. The locations have been given numbers and will be used in the accompanying charts to identify the positions of O2sensors in most vehicles. Due to mid-year production changes or factory inconsistencies, all models may not be covered.

What kind of bulb does an O2 sensor use?
A zirconia bulb lined with platinum facilitates the transfer of the oxygen ions between air inside the sensor and the exhaust gases that flow over it at temperatures higher than 600 degrees Fahrenheit.
