location of 02 sensors on an 05 Ram Hemi

[Jim Ramstad]

Looking for a diagram of where the 02 sensors are actually located on an 05 ram with the hemi. The haynes manual is poor as only shows two of them and the auto parts stores show there are 4 of them. Any help would be greatly appriciated. Have on that is slow to react when we did the diagnostics on it. Need to figure where it is so I can replace it.

They shouldn't be to hard to spot. There will be one before the cat and one after the cat. If there are 2 cats than there will be four sensors. If there is one cat that there will be a sensor on each back before the cat and one after the cat for a total of three.

What code did you get. Bank one will be the same side of the engine that the #1 plug is on. Bank 2 is the other side. Sensor 1 is before the cat, Sensor 2 if after the cat. So if it was a code for bank 1 sensor 2 it would be the side of the engine that the number one cylinder is on and the sensor after the cat.

the code was for the Bank no. 2 sensor no. 1. Which must mean there are 4 of them and Auto zone shows it being in the manifold but not very visible. I am guessing this is what would be a before converter 02 sensor?

Ok. I see what you were saying. I ordered the one for the before the cat so I should be in good shape weather there are two or four sensors?
