P0138 oxygen sensor 2001 Ram 5.9L Gas

Could someone please tell me the location of this sensor on my vehicle from recieving this code. My check engine light came on and I put my code reader on the truck.

Code# P0138 (o2 sensor circuit High Voltage) Bank1 Sensor 2

2001 Dodge Ram 1500 4x4 5.9L (gas) with 108 000 km
Could someone please tell me how many o2 sensors there is on my vehicle?

its definitely one of the sensors after the catalytic converter. if it only has one cat... easy enough. if it has 2, youll have to find whitch side manifold they are referring to as bank 1. bank = left or right side. sensor 1= before cat. sensor2 = after cat. oh yeah... if you have one cat., you have 3 02 sensors. if theres 2 cats, you have 4 o2 sensors.

i have a 01 ram also, and i only kno about 2 o2 sensors, ones infront of the cat and ones directly behind the cat. where is the third sensor located?

there is only 2 o2sensors on this application and code p0138 refers to the one just behind the cat
