Hello! Recently my check engine light came on. I have an OBD-II code reader, so I read the code and it showed an error code of P0141. Upon researching this code it looks like one of the oxygen sensors on the car needs to be replaced. The problem is I am not sure exactly what sensor needs to be replaced. I keep finding conflicting information on if my car has 3 or 4 sensors and I keep seeing different labels for the sensors. The code is saying it is the sensor in (BANK 1, SENSOR 2) that needs replacing. If my car has 4 sensors (one on each side of the V, one before the Cat and one after the Cat) I am assuming that it is the sensor before the Cat and can be reached from under the hood. If my car has three sensors(one on each side of the V, and one after the Cat), then I'm assuming that the sensor located after the Cat is the sensor that needs to be replaced and that the car will need to be jacked up and the sensor will need to be changed from underneath the car. Thanks for any help you can provide me with.
