if you leave your TPS disconnected, your mileage is going to be bad and your check engine light is going to be on....check the ohms on your tps to see if you need to adjusted or replace it....i'm having the same problem with my tps, thats why I couldnt pass my smog test...

 

mine just started doing it. i didnt pass smog a while back due to my blown head gasket. after that it passed. do i check the ohms with the motor running? what should it read?

 

no, you need to take off the body throttle off from the engine, there's a link to download the manual for this truck here at yotatech. is one the is stinky, on top of the list of tread....

 

is there a way to keep all of the coolant from pouring out of those hoses attached to the throttle body?or a way to do it on the truck so that i dont have to fool with those

 

what I would do is find some bolts with the same diameter of the hose...take off the hose from the throttle body and put the bolt on the hose and used the some hose clamp.

 

alright so i do the check by putting the ohm meter on each post and move the throttle around, correct?

 

thanks man il look at that fsm on how to test it.and hopefully get that fixed. Thanks to everyone else too who put into this thread.

 

That's the cap for the internals of the idle air control valve.

 

I changed the name of your thread by the way - the other one was way too ambiguous.

If you don't like this one then give me another more descriptive one and I'll change it for you.
I'm going to unsubscribe to this thread so just shoot me a PM with it.

Hey guys, i am in the process of checking my tps. When i do the resistance check they all seem to be within standard. Accept from terminal IDL-E2 isn't even getting a reading. could this mean i need a new tps? Here is a link to the test. http://www.the-roo.com/4runner/Engin...m/throttle.pdf.It would seem that there is something wrong with the IDL terminal.
