Toyota and Lexus T-0122-10-dtc0136 to 0141.bin Firmware
A catalog reference for T-0122-10-dtc0136 to 0141.bin and its oxygen-sensor diagnostic trouble code label.
T-0122-10-dtc0136 to 0141.bin is a firmware file whose label names diagnostic trouble codes P0136 through P0141. These codes concern oxygen sensor circuits and heater circuits associated with the engine’s exhaust emissions monitoring system.
What the diagnostic label means
Oxygen sensors help the engine management system monitor exhaust gases. The codes named in this file cover conditions such as a circuit fault, insufficient sensor activity or a heater circuit fault. A sensor heater helps bring the sensor up to operating temperature after startup.
The dtc0136 to 0141 wording suggests that the file is associated with that diagnostic code range, but it does not establish whether the software suppresses, changes or otherwise handles those codes. The filename alone also does not identify a specific Toyota or Lexus vehicle, controller or calibration application.
