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 [IMG]local://upfiles/7850/159ECCDBAF8D4D198D21BB6B70FCABF1.jpg[/IMG] [IMG]local://upfiles/7850/871FF8C00C1942188A8C0E643A987110.jpg[/IMG] |

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; [IMG]local://upfiles/7850/33E9AF64268147B0B3E14D2B71C12B3B.jpg[/IMG] |

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 |
