p72...code 61 is primary o2 sensor

 

P0133 = flashing-CEL code 61 = primary O2 sensor slow response. I thought that code didn't exist until OBD-2 ('96). That's why I asked what ECU.

Slow response is the kind of code that isn't likely caused by bad wiring. There's different codes for low or high voltage, those can be caused by an open or short. So it's still kinda confusing to me, since I figured the response of the sensor didn't change from OBD-1 to OBD-2, only the newer P72 ECUs had more stuff programmed on it.

 

do you guys know if the 96+ obd2 gsr have 2 o2 sensor or just 1?

 

ALL OBD-2 cars (beginning in 1996) must have another O2 sensor after the cat.
