P0031 code and sensor location
Hello,
I do have a P0031 code since last Friday on my 2010 4Runner Trail Edition (Canadian). The code description: P0031 - Oxygen (A/F) Sensor Heater Control Circuit Low (Bank 1 Sensor 1).
I do have a few lights lit (Engine check, Terrain select (flashing), traction control) as seen in the attached image.
I've looked into the Repair Manual for the sensor location and only find the Bank 1 Sensor 2 and Bank 2 Sensor 2 sensors on the diagrams. Anyone knows which one it could be or where to locate the Oxygen (A/F) Sensor Heater Bank 1 Sensor 1?
I'm trying not to go to the dealer with this, but having no traction control is not fun during winter...
