Toyota Mechanic: Peter Bagley, Auto Service Technician replied 8 months ago

It only blows when throttle applied? Have you tried stepping on the throttle pedal when engine not running but key on? Let me know what happens . I will check back with you tomorrow and review my shop wiring diagrams.

great thanx for that info , going to check the wiring diagram right now.

Toyota Mechanic: Peter Bagley, Auto Service Technician replied 8 months ago

this will be very difficult to check if it only does it driving as this fuse runs a few major things , I will try to send you the wiring diagram but may not go through as it is from Our electronic files . I also think at this time a service would be beneficial to proceed with.
