I have seen a lot of questions about weather all 4 wire o2 sensors are the same. Well, I found out they are not. The sensors operate on different frequencies, so not all 4 wires are the same.
I found this out after my o2 retrofit, I was getting an o2 code for a long time, along with a lambda #1 code and engine speed code. One I got the engine speed code fixed I have not gotten any other codes since then.
I have put about 300 miles on this new o2 senser and have not gotten a code.
First off, I went to Advanced Auto Parts and got a bosch o2 sensor part number 13275 Its supposed to be for a Chrysler concord or Dodge intrepid I think.
Cost me $45 vs the $100 they wanted for the BMW sensor.
Procedure:
Here are the two o2 sensors next to each other. Top is an OBDI s50 sensor, below is the $45 sensor.
Although it shouldnt matter, mark one of the white wires so you can put them back together correctly. All I did was look at the o2 sensor from the wire side. I put the black wire up top, white to the left and right, and grey blow. That way I knew the marked one should be the left white wire when looking at the new o2 sensor with the black one on top.
Cut
Strip and be sure to leave the heat shield for the wire on.
I found the best way to connect the two wires, was to get a 4 pin power plug, male and female, from rat shack. I think it was like $2 in parts. It should be straight forward. Crimp the plugs onto the wires then smush them in the plastic housing.
MAKE SURE THE WIRES ARE CRIMPED IN WELL, one of mine came out and caused some problems. Just tak a volt meter and make sure its all together. Give them a little tug once they are in the housing to make sure they do not slip out.
I originally tried to solder them together, I dont know what the hell kind of wire this is but it will not solder. I tried flux and everything it just wouldnt stick.
Heres the two parts
And the final cable
The red wire with the yellow nut is a tap on the black wire that I used to connect my AFR guage up to.
Now just screw it back in, plug it in, and go.
This worked for me, I dont know if it will work for you. But you can try it I guess.
