Every once in a while (4-5 times over the past 9 years), I've gotten a P0161 (O2 heater performance Bank 2, downstream, after cat) code, but there's never been anything noticeable as far as runability. I got the P0161 in December and again this week. But, now I'm seeing 2 new codes I haven't ever seen before: P0155 (O2 sensor heater performance Bank 2, upstream) and P1153 (O2 sensor insufficient switching Bank 2, upstream). I figure the P0161's may have just been anomalies in the past, but now that I'm seeing BOTH the P0155 and the P1153 for the upstream sensor that it might be a sign the sensor is malfunctioning. Or, should I just wait and see if it's just another anomaly? If you've gotten P0155 and P1153 codes, did replacing the sensor fix the problem? Description
