The check engine and TCS lights came back on in my car. I pulled the codes and it shows:
P0155.02 Sensor Heater Circuit (Bank 2, Sensor 1)
P0141.02 Sensor Heater Circuit (Bank 1, Sensor 2)
P1202
P1203
P0300
The last three codes came on a couple of years ago, but then went away. The car still drives normally without any problems. By searching this site, it seems like I need to replace a couple of oxygen sensors. Is this right? What are the part numbers? Where is the best place to buy them? Is this an easy DIY job? Thanks in advance.
