2007 honda accord v6 bank 2 sensor 1 location

Code P0174

 

Bank 2 on your V6 is towards the front bumper of your car, so the Bank 2 Sensor 1 is on the exhaust manifold or downpipe before the catalytic converter after the 3 exhaust pipes merge. It should be pretty easy to access vs the bank 1 sensor in the back of the engine.
