-
had code P2207 O2 sensor signal stuck lean-bank 1, sensor 2 replaced O2 sensor.
check ecgine light went out for about 3 weeks.Now light back on checker shows P2207 again
-
Let me check if I can find more information. What is the model and year of your vehicle? do you have any exhaust leaks?
-
The oxygen sensor is by far the most common problem for the P2270 code, I checked a national database of repairs and found that in some cases it is also necessary to reprogram the Powertrain Control Module (PCM). Before reprogramming the PCM, make sure the O2 sensor is firmly connected.
