P1155 Code

[dsedge]

I recently had the EMS light pop up. I had it tested and it came back with the p1155 code for the bank 1 sensor 2 fault, so got that fixed but the light won't go out and when i tested it again it comes up with p1155 undefined code as the problem does anybody know what this means??

Hi mate - welcome to the club.

Please go back to your details and add as much as you can about your car.

The code points back to your oxygen sensor;

What do you mean by you got it fixed. Was it a new part with a warranty?

I got the same code. Something about a A/F heater circuit. What's the harm if I don't fix this right away?

You probably won't notice any difference although it could be affecting the emissions slightly.

If you have changed the sensor did you reset the EMS with the code reader afterwards?
