    I have two codes right now 0135 and 0136 for the bank 1 oxygen sensors. ...my question is, what is the difference in all of the sonsors I am seeing, the one thats on the front of my car now looks like this...

    Doesnt make much difference as long as it has the same number of wires! Get a Ford part or a Bosche part. Do not waste your money on a parts store brand unit

    i'll add that there's some with 2, 3, or 4 wires. The connectors will connect, but will not operate correctly unless the wires are the same as your factory harness

    Yeah they are all 4 wire on my car, just didnt know if there was a difference between the skinny one or the fat one....ive heard of "heated" o2 sensors but never looked much into it....also, is my front one supposed to be touching my starter, seems too tight of a fit...
