I just installed KPRO into an 02 RSXs. Getting error code P0134. I am using a PRB ecu with KPRO v.1.4.1. Is there a way to test primary O2 sensor before I replace it? Additional information, car was turbo-charged for 4 years until manifold cracked. Now car is stock except for toda cams, test pipe and exhaust. 60k miles on O2 sensor. Thanks for the help

Try the sensor in a known workign car, or try a known workign sensor in your vehicle.
