My check engine soon light came on. Ran a diagnostic code read P0141.

Checked gas cap, put in some fuel injector cleaner and the light went out. Should I still replace the sensor? Bank 1 Sensor 2, where is it located?

Answer 1

Hi there,

In most cases if the light comes back on you will have to replace the sensor. It is located directly behind the catalytic converter under the car.
