Pluged in the computer to my truck and it said there is a o2 sensor malfunction of bank 2. how do i find it? also it says the truck is running to lean. is this cause by the o2 sensor?


Yes, this too lean runing engine is due of oxygen O2 sensor malfunction. Must be replaced with new one. You can find it very simply on bank 2. The bank 1 of V8 engine is the cylinder bank on the right (passenger's) side of the car, (for Left Hand Drive vehicles). So the bank 2 is placed on the left (driver's) side of the car, (for Left Hand Drive vehicles). The bad oxygen O2 sensor is fitted on bank 2, so you can replace it.

Please rate my response. Thanks!
