P1135 code

how do i fix this and how do i reset

First, what IS P1135 code? It’s a DTC trouble code for: The front A/F oxygen sensor heater circuit has a malfunction (bank 1) on your Toyota Avalon 3.0L V6.
This could be from a broken wire, poor connection, or a bad A/F oxygen sensor (also, called, “Wide Band oxygen sensor”). The sensor is too expensive to just replace it to see if that will take care of the malfunction. The A/F heater circuit needs to be checked with a multimeter.
You could remove the EFI fuse, wait 2 minuets, and reinstall the EFI fuse, to erase the trouble code. If the cause is still there, the check engine light will come ON the next time the engine is started.
