yes i did a search on here and other sites!! and i got alot of diffirent info on how to test it!!

but i came to the conclusion that i check the tps's middle wire(red) with a volt meter.

but do i have the car running? off? turn'd on to the acc. switch? what?

also where do i set my volt meter to?

any info on this would be a great help!!

thanks

 

Wanting to know this info also. Help us. I need to pass emissions with my Prelude. Check engine light is an automatic failure here.

 

set the range to 20 on the voltage setting and probe the center wire with the key in the on position , check reference voltage at idle(just key on) and at WOT(depress the gas pedal)

service manual has the voltage range listed.

 

Acc is on when you set it.

disconnect check engine light lamp.

 

I would but it will still fail. I did that last year. Then I dished out $150 to pay the guy to make it pass. This year they are REALLY strict. Alot of places got either shutdown or their emissions station closed so far this year. LOL

 

This is how you test it. You need a digital tester, makes it easyer to work.
First, cut a small window on the insulation of the middle wire at the TPS.
Next, turn the ignition key to II. The dash lights should come on, but don't start the engine.
Take the red lead on the tester and place it at the middle wire on the TPS. Take the black lead on the tester and place it on a good ground in the engine bay
The voltage there should be anywhere from .45 to .5 volts.
rotate the throttle body pulley and the voltage should go up to almost 5 volts at WOT.
