2003 6.0L P0138 & P0140 o2 sensor errors
I get these error codes for Bank 1 Sensor 2 o2 sensors, where are they located?
Where are sensor 1 and 3 located?
I have 130,000 km on the truck so I think it is time to replace the sensors anyways.
Thanks

I put up 2 images (attachements).
The engine one is bank 1 sensor 2
The image of just the exhaust is bank 2 sensor 1

Sorry about the images not being clear.
This is what each code means;
P0138= HO2S circuit high voltage
P0140= HO2S circuit insufficient activity
Here's a better image of where which sensor is where;

Oh yeah,
According to the shop manual,
P0138 is either Bank 1 Sensor 2 or Bank 2 Sensor 2
It's the same sensors for P0140
In case you were wondering,
P0131 or P0132would be forBank 1 Sensor 1 and Bank 2 Sensor 1
Hope this helps
