I was told i have 2 sensors going out, but not which 2 and am not sure how
many the car actually has.

Make sure the 02 sensors are the actual issue before replacing. A lot of times an 02 code will mean the sensor has detecting a problem, not that they are faulty.


When the machine was hooked up to the car, they said it was reading 2 sensors going out and it had pinged the computer 12 times.
