Service Engine Soon Light with P0155 code

GAM3OVR85 · 03-22-2011, 04:30 PM

I just had a service engine soon light come up on my 07 e92 328i, i scanned the car and it gave me this code P0155 and it said O2 sensor heat circuit malfunction (Bank 2 sensor 1).

Does anyone have an idea what it could be?

I have these mods:
-PBX
-Injen intake
-BMW Performance Exhaust

Thanks in advance

PBX may cause it. Try turning it off completely and resetting the code. If it comes back, it's not the PBX.

I still have to delete the code and see if it comes back again. Either way, i'm going to bring it to a mechanic. There is spots in the the engine bay and every time i turn on the heater, i smell something burning. Had this problem before the light came on but didn't realize the oil in the engine bay....i'll take a pic of it tomorrow!

And could the SES light be from the intake? I have injen intake and haven't cleaned it in about 2 years lol.

Twice I noticed my car shaking at a red light and looked at the rpm and it was at 0.5 for a second
