i did a code check, and got a 32 code. o2 sensoe 1 right side. in my mitchel on demand program it says to test if it has 12 volts at the plug. (both o2s do). and to test the o2s for ohm restors. black and white. when i put ohm meter to the black and white nothing, ol. white to white i get 6.2 ohms on both. are they still good or bad?
