Problem??
CEL came on today with the following codes:
P0050 HO2S Heater Control Circuit Bank 2 Sensor 1
And
P0155 O2 Heater Circuit Bank 2 Sensor 1
I know that code "P0155" is for the oxygen sensor right? Which means I have to replace it; what does HO2S means then? Any idea on the location, front/rear - right/left?
Thanks!
