I think you may have mis-read the code, or your OBD-II tool is giving you bad information.

P0105 indicates a defect in the MAP circuit ... something associated with the MAP (Manifold Absolute Pressure) sensor.

You're not finding anything relating to FJs because the 1GR-FE engine does not have a MAP sensor. It does use a MAF (Mass Air Flow) sensor.

Go back and read your pending codes again ... if you get the same erroneous result, try a different code scanner.

I had my lights on for 100000 miles. Changed the gas cap. Nothing. Three mechanics had all kinds of tests. Since gas prices dropped I put in the good stuff. Only shell 89 now and no lights. No more Kroger or Walmart gas. They came on and off while I was testing it. I'm at about 5000 miles off now.
