    I have a 2003 Tacoma SR5 2.4 L engine. I'm trying to find the heater fuse for the O2 sensor. there doesn't seem to be one in the engine fuse box or under dash fuse box. Does anyone know where it might be?

    There isn't a dedicated fuse for the AFR & O2 Sensor Heaters, they are powered by the EFI Relay which is fed by the EFI Fuse (20A) and ground to them is controlled by the PCM.

    The truck wouldn't run if the EFI Fuse was blown and/or the EFI Relay wasn't turning on.
