Hi,

Please somebody tell me what this code means and which part I need to replace? The guy at AutoZOne could not find it in reference book. Appreciate any help that you can provide.

I looked into my few manuels that cover these codes and found none that start with 1, they all start with 0. You may try using an Actron Scan tool, it not only displays the code, but also scrolls out the code definition.

P1150 is: Air/ Fuel ratio sensor heater circuit (bank 1 sensor 1) In other words the heater circuit for the bank 1 sensor is bad. Replace the O2 sensor in that circuit and clear the code.

Conversation Summary

The owner of a 2000 Toyota asked what check engine code P1150 means and which part to replace after AutoZone could not identify it. One reply noted that available manuals listed codes starting with 0 and suggested an Actron scan tool for the definition. An expert identified P1150 as the air/fuel ratio sensor heater circuit for bank 1 sensor 1 and recommended replacing that O2 sensor and clearing the code.
