Well my check engine light is throwing a 41 code error which means o2 sensors.. I plugged in one for downpipe and im using my ek harness odb2 so your gonna use 2 sensors. I tried to plug in the second sensor in the front but cant find a sensor on my header anywhere.. btw its a stock gsr header.. what can I do to bypass the 2nd o2 sensor?

 

anyone?? Im trying to bypass the second o2 sensor like the one on a single cam header where the cats suppose to be because Im using a single cam harness for a gsr motor... but since the b series doesnt have a cat on the header theres no need for another 02 sensor cept the one on the down pipe...engine check light keeps comin on for that error

if the gsr is a 96 and up, then yes it has a secondary O2 sensor. if the cat was removed and the light is getting on your nerves you can always remove it. i can be wrong, but to bypass the sensor i believe take reprogramming of the ecu.

 

Check it! Easy and cheap if u still have a cat.

If not, ive heard u can wrap the o2 in tin foil and zip tie it out of the way.

Make sure u have the primary plugged in and its the secondary that is no longer needed.

really?? will that work? I think the primary use of the second o2 sensor is to measure how hot the cat on the headers are in order for the computer to calculate how much fuel to go in and out.. I took out the sensors from my single cam and just plugged it in.. no check engine light when I just turn it on but when I start the car after about 5 secs it comes on.. you think the sensors not hot enough??
