First of all I want to thank all of you that monitor and answer these questions. Reading this forum and following your advice has already saved me hundreds of dollars and that is a BIG deal!
Now to the point.
I bought a inexpensive code reader when my CEL kept coming on and my mechanic seemed generally unable to fix the problem. I recently replaced my transmission and after its repair I began to have problems. I had the transmission range sensor replaced and when the CEL came back on I plugged in my handy code reader and the error codes turned out to be associated with my oxygen sensor (#136 and #141). In response to an earlier post I learned these codes corresponded with Bank 1 Sensor 2 (Post CAT, passenger side) I replaced the sensor with a Borg Warner purchased at Kragen (part #os136) This is the OEM version. When I changed out the part I noticed some heat damage to the OEM connection, but by that time I was running out of time, so I plugged in the sensor, cleared out the error code and went about my merry way. A couple of days later the CEL came back on and it occurred to me that the damaged OEM plug may be to blame so I crawled back under and low and behold, the plug was actually so damaged it didn't seat properly. Feeling a little stupid for not checking the connection more carefully I cut off the OEM connector (both ends) and went about splicing the wires directly. After I got the wires cut I noticed that the OEM connection on the aftermarket O2 sensor had a black, grey and two white wires rather then 4 separately color coded wires. Feeling less smart then before (if possible) I crimped bullet connections so that I could switch the white wires if the error code (CEL) came back on. I plan on rechecking my connections and possibly doing a little soldering to ensure good connections and double checking the wiring.
My questions are:
Is there really any problem with having the white wires switched?
Is there anything else that I am forgetting?
I noticed that the appearance of the BW sensor was different from the Bosch sensor that it replaced. I realize that the physical appearance is not necessarily determinative, but the picture on the Kragen website shows a BW sensor that looks like the Bosch sensor (fatter body). I know its unlikely, but is it possible that the wrong part got put in the box. I plan on going back to Kragen and asking to look at another boxed sensor to confirm.
Thanks in advance for your help.
