I have a 2002 Toyota Highlander (V6, 2WD) with a Check Engine Light activation. The OBD-II scanner shows only one code - P1155; the description I have been able to find reads "A/F Sensor Heater malfunction Bank 2 Sensor 1". My Haines Manual has proven worthless to me.
I would like to know exactly what this means, where the sensor is located and if this is something that I can address myself?
have the same problem?
