Bank 1 Vs Bank 2 Sensor 1 2 How To Locate O2 о The 1st sensor is located closest to the engine, and the last is located toward the rear of the exhaust system. generally, if we are talking about o2 sensors: sensor 1 = before catalytic converter front (upstream o2 sensor) sensor 2 = after catalytic converter rear (downstream o2 sensor) some diesel engines have many exhaust temperature sensors. Find the upstream or downstream o2 sensor. once you’ve determined where bank 1 and bank 2 is, find the o2 sensor that needs replacing. then you can compare it to the new one to confirm you have the right oxygen sensor. check and compare the o2 sensors features. as shown in this article’s video at 2:30, we can confirm which oxygen sensor.
The Difference Between Bank 1 And Bank 2 When Locating O2 Sensorsођ A vehicle’s (bank 2, sensor 1) o2 sensor will be located ahead or upstream of the catalytic converter on the bank which corresponds to the engine’s second cylinder. this is due to the fact that bank 2 is representative of an engine’s #2 cylinder, while sensor 1 serves as an upstream designation. example dtc: code p0154, code p0175. Bank 1 sensor 2 is located downstream, usually right behind the catalytic converter. bank 1 sensor 2 measures the composition of exhaust gases and helps determine if the catalytic converter is working properly. a bad bank 1 sensor 2 will trigger the check engine light and cause codes such as p0136, p0137, and p0141. 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 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. The oxygen sensor is an item in a vehicle that gets replaced due to the fault of another component. just because a fault code indicates an oxygen sensor problem, don't just replace the o2 sensor.

The location may be reversed in rear wheel drive vehicles, with bank 2 closer to the engine and bank 1 further down the exhaust. v engine configurations often have one converter per bank, with bank 1 on the driver’s side and bank 2 on the passenger side. inline engines may have both converters in a row, with bank 1 closer to the engine. Method 1: the manual method of locating oxygen (o2) sensors. step 1: find bank 1 and bank 2. we have explained what bank 1 and bank 2 means in the previous section of the article. if you want to locate the different banks and sensors in your car engine system, you must first understand the type of engine you have.
