One of the oxygen sensors in my car is being a PITA and shorting out… and it causes a fuse to pop in my DME and then throws the car into limp mode…
I need to figure out which o2 sensor is causing the fault…
Does anybody know if you can test resistance on them to see if a short is present?
Will the heater circuit show continuity when tested if good? or should it show an open circuit??
Its kind of a PITA for me to change the 02 sensor with the headers, so i would like to be able to know which one is DOA before diving into swapping them
