Hi Guys
Over the last few months my emission light has been coming on once or twice a month - I have a code reader and have recorded 0036 and 0141 codes (mostly 0141) I reset them and wait for the next occurrence. As I guess I expected it now comes on each day with an 0141 code which of course identifies O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2). I have scoured the forum and have read a number of similar posts but none seems to identify which of the two sensors it refers to and it seems clear that sometimes the code may be misleading and I am obviously loathed to replace anything unless I am reasonably sure it is the problem.
I didn't mention it but the car runs fine with no obvious indication of any problems.
So my questions are:
1 - Which sensor is Bank 1 Sensor 2?
2 - Is it likely to be the problem?
3 - Any other suggestions?
