How do you know the fuse has blown?

Replacing a good or blown fuse, will not fix anything

Fuses blow for a reason

The fuse is the small item you can see into & you pull it out

Ask a neighbor for help

Bad throttle position sensor

first you must disconnect the throttle body components, then take off throttle body. then you should have full acces to your intake manifold. you should also beable to see all the nuts or bolts that hold the intake manifold in place. unbolt them and take it off. keep in mind you are going to need to buy a new intake manifold gasket befor putting it back on. good luck

when a battery is installed backwards for any amount of time it blows fuses mainly the large ones in the under hood fuse box

On the engine compartment, check the cavity 13 20Amp (car audio systems). Also can review the 2002 Toyota Sienna - Owners Manual (page 321).

Hope helped with this (remember rated this help) Good luck.

After about 100K + miles the idle air control valve (IAC) begins to collect carbon deposits that interfere with the movement of the spring-loaded valve. You will not be able to clean this without removal and dissembly of the IAC body. Use an emory cloth or fine sandpaper to remove the build up around the valve. This should free it up to rotate without binding. This is a temporary fix, of course, and will either require cleaning again or replacement of the valve. Getting to the IAC requires removal of most of the intake upto, but not including, the intake manifold. Total time is approximately 3-4 hours, but worth it. Good luck, and I hope this helps.

Souns like either a dirty throttle body, a bad throttle body, or bad IAC. I would clean out the throttle body first. let me know

your talkin a good chunk of money definitly over 100 dollars i would think after the labor cost probably around $350.....
