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.
