: Dts P0155

02-28-06, 11:02 PM
My check engine light came on yesterday. I went to Advance Auto and had the code read today. The code is P0155, 02 sensor heater circuit malfunction, bank 2 sensor 1. Has anyone had this problem or know what to do?

Thanks Jeff

will give you the meaning of your P0155 code, along with a few others.

You most likely are going to have to replace the sensor.

Be sure the sensor wiring is intact and continuous, and that there is no corrosion on the sensor contact(s).

Good luck!
