O2 Sensor code - P0053 Heater resistance Bank 1 Sensor 1

[Enjoyneering]

Good day everyone.

A week ago I changed the injectors gaskets and error code P0133 gone.



However P0053 was still present. So I went to the store and explained the issue: the new sensor has resistance of 5 Ohm, the old from the car has 10..11 Ohm. They agree to exchange. Next day I got a "new" o2. The sensor has some dents and scratches on the nut and missed anti seize grease but the protective cap was shiny (maybe they put it on the car for test before???). After I put it on the car the P0053 gone right away. Had pending P0171 for a day and next day it gone too.
