i started using my friends non chipped pr3 and now im getting a code 2, maybe its a 20 im not sure. everything seems to be ok. the vtec doesent work like always. whats going on?

 

thats seconday o2 sensor. 20 is electronic load i think it deffinatly would be a number 2.

 

Thats interesting.. I didnt really know for sure if the PR3 ECU had a secondary O2 ..Hell, its a OBD-0 ECU!!

What would be done to eliminate the secondary O2 wiring?

 

my car once through a code 20 which is the eld located under the engine bay fuse box. it also made my vtec not work. after lots of trouble shootin i found that it was a wire that had grounded out under my dash. if you havent fixed the problem yet hit me back and ill give you the steps to find out what the f@#$ is going on
