The check engine light on my 2008 Highlander (non hybrid) came on last week. Checked the dtc and got P2192 system to rich at higher loads bank 1. Vehicle runs and drives fine. Cleared the code and it came back the next day. I was told by the dealer over the phone to check and make sure the gas cap was on properly which it was. I have searched every where for a reference to this dtc but can not find one. Any help would be appreciated.

take the neg. battery cable off for about 15-30 minutes and then put back on.Be sure to turn the headlites on before taking it off and putting it back on. It did the trick on mine a while back... Good Luck
