P0138 Code on a single exhaust
Please help. I'm getting a P0138 code on my truck. Its a 5.7 Hemi 4x4. I read what the code means which is O2 Oxygen Sensor Circuit High Voltage Bank 1, Sensor 2. Problem I'm having is that I only have one exhaust pipe. Can anyone tell me how to solve this riddle. I spoke to the dealer and by pulling my VIN it tells them I should have two exhaust pipes. Your help is always appreciated.
