2003 Toyota RAV4: Engine Codes P0141 & P1155?

Both this error codes are related to Heater Element.

Proper inspection is required.

The P0141 code means that the heater element in the oxygen sensor bank one sensor two or B1 S2 has failed. This in itself will not cause an igniter problem Or a performance problem. Code P1155 means that the heater element in the AFR sensor or air fuel ratio sensor for bank two sensor one has failed. This is identified as B2 S1. This also will not cause an issue with performance or the igniter problem. In most of cases it ends up just being a bad sensor. Make sure that you replaced the correct sensors.

This details will help.
Thanks.
