My car spit out 8 codes the other day i replaced 1 out of 4 o2 sensors, cleared the codes and now it is only spitting out 4 codes but still the same 4 as last time.
(P0135) o2 sensor heater circuit malfunction Bank 1 Sensor 1
(P0141) o2 sensor heater circuit malfunction Bank 1 Sensor 2
(P0155) o2 sensor heater circuit malfunction Bank 2 Sensor 1
(P0161) o2 sensor heater circuit malfunction Bank 2 Sensor 2
Why would it still be saying ther is a problem with all four sensors even though i just replaced one?
And what would be causing all of the sensors to be malfunctioning like this?
