is there a picture or a diagram somewhere to show where it is for a 2003 accord v6.

thanks in advance


ps pretty sure its bank 1 sensor 2 due to p0138 and p0139 codes

Bank one would be the odd numbered cylinders. Sensor 2 would be the 2nd one from the exhaust manifold back.

Yup bank one is always the same side of the engine as the number one cylinder. Sensor 1 refers to the sensor before the cat, sensor 2 is the sensor after the cat. So Bank1 sensor 2 would be the sensor on the same side of the engine as the number one cylinder and after the cat.
