OBD1 ecu throwing code 65, secondary o2 heater??
Well, here's the story.. I have a boosted B16A in my '96 coupe converted to OBD1 with a chipped P75 ecu tuned by me on crome free.
Today I setup the anti-lag and noticed my CEL was on. After pulling the code I realize it's 65; secondary o2 sensor heater. The weird thing is, first off my tune is open loop (disabled o2 sensors), and second OBD1 doesn't have a secondary o2 sensor.. so WHY am I getting this code?
I use my CEL as a shift light so I really need to get this fixed. Any help is greatly appreciated.
