Bank 2 Sensor 1 is located before the catalytic converter on the side of the engine opposite to Bank 1. It’s crucial for monitoring the air-fuel mixture.

Exactly, and it helps the ECU make adjustments to optimize performance and emissions!

Also, Bank 2 Sensor 1 differs from Bank 1 because it measures on a different set of cylinders. Understanding this helps a lot with troubleshooting!

Bank 2 Sensor 1 is often located on the passenger side of the engine, near the firewall. That’s where I found mine on my 2013 Toyota Camry.

That’s interesting! I have a 2015 Honda Accord, and it was located in a completely different spot, near the catalytic converter. Always check your manual!

My 2009 Nissan Altima had the sensor located on the passenger side as well, but it was a bit tricky to access. Definitely recommend removing the air intake.
