i stripped my upper o2 sensor (in the exhaust manifold) yesterday on my 98 ex and was told that its the same as a 92 lx so i bought that and it threaded and plugged right up...its still throwing a check engine...reset the ecu and dont know what to do.. anyone?

What is the exact code?

If you could get the CEL code that your getting, that would be extreemly helpful. It could be a few things, but you first should by the 02 sensor that is specific to your model and year. I assume you have your stock headers? sense the o2 sensor is screwing into the manifold... If you did not buy a direct fit you had to splice the wires... make sure you have the wires connected to the right ones ( the ground is connected to the ground... etc. ) if you put the heater wire to a ground, or got something mixed up... it will kill the circuit and throw a CEL code. If the 02 sensor that you put on there works for your model and year, its also possible that the 02 sensor that you put on there was bad as well.

1. Pull of your CEL code and research it and probable causes.
2. Get the 02 sensor that is direct for you model and year ( they should be around 60.00 at an auto zone for a non direct fit )
3. make sure each wire is connected to the correct circuit.

hope this helps

thanks man im gonna run the CEL code wen i get out of work.... i got the sensor from advanced auto its a plug and play type.. i didnt have to splice any wires or anything so idk what to do..i dont think i can return it because it is already used...guess im gonna suck it up and by the exact one

I am also throwing a code for 02 sensor because I have no cat. Is there a way to buy pass this I heard YOu can put it into the header and I would not need to buy a new cat. Is this true?

this is not true. Assuming that you have an OBD2 ecu with no catalytic converter on your car. simply putting another bung in the header WILL NOT WORK.

If you have an OBD 0 Vtec ecu and you are getting a secondary O2 sensor code, then you can fix it by installing the second O2 into the header in the location pictured below.

you can use an o2 simulator

i got the one for my exact car and CEL is gone and runs beautiful thanks guys
