i checked my code on my 2000 gsr and it blinked a 41. can anyone confirm a primary o2? also, i am speculating that my vtec is not working, due to a early fall of of my power band (i am turbo) i was told a 41 would disable vtec is this correct? anyone know how to fix this?

 

Yep. Open or short in Primary Sensor Heater circuit.

 

would this cause my vtec to be disabled?

 

I'm not sure. I got this code on my 91 accord lx. No vtec. It caused my car to idle funny. I changed my O2 sensor and it's gone now.
