TeejayBee Posted April 23, 2010 Report Share Posted April 23, 2010 Alright guys im just double checking to make sure i pull the right sensors . I had to do a code pull at work and it came up with Codes P0135 - O2S Htr Circuit ( Bank 1 Sensor 1) P0155 - O2 Sensor B2 S1 Htr Ckt Malfunction Now there are three O2 sensors through my exhaust If im correct it is the First two on the Pipe . If im correct the first is located Right under the Drivers Feet. and then the Second is located near the Passanger Seat or near there . I just want to make sure im doing this correct before i do anything tomorrow. Quote Link to comment Share on other sites More sharing options...

dyeagain15 Posted April 23, 2010 Report Share Posted April 23, 2010 (edited) On a v6 engine, bank one is the side with the first cylinder farther forward. Like if you look from the front they are kind of studder stepped all the way back. It will be the sensor before the catalytic converter on that side *edit* both sensors you need to change are before the cats Edited April 23, 2010 by dyeagain15 Quote My F-150 Build (So Far) 2 DC L3 10's Kenwood KDC-X794 (4) Selenium ST200 (Highs) (2) RE X8 (Mids) Sundown Sub/Mid/High Amps Shuriken Batteries Knu Wiring My Feedback Thread Link to comment Share on other sites More sharing options...
