ok guys im lookin to buy a tps off e bay.. and i waz wondering if when i out the new one on do i have to get the ecu tuned?

 

I don't know what you are referring to?

TPS= throttle position sensor











Or are you talking about the throttle body Below [&:]

 

throttle position sensor i belive mine to be goin bad i have sturding bad mpg i have half the power of what i had b4 and stalling... does this sound like a tps if not what do you think it could be i do have a bad vavle seal in my head but i dont think it would do all this, do u?

 

You can test the TPS to make sure that is the reason for your issue. Heres what you do.

Pick up a multi meter like this ($15 at Autozone, Lowes, etc..)





1 - Turn your key to the ON position (but do NOT start the car)
2 - Then, using the red probe provided with the multi meter, tap into the middle wire going into the tps
3 - Once tapped, put the other probe onto a ground source (I usually just use a bolt on the Throttle Body)
4 - You should see a reading of 0.45-0.50 with the throttle plate closed

Now, do steps2 & 3again, only this time with the throttle plate completely open (this is a lot easier with two people, but it is possible by yourself, just get creative, haha)

The reading with the throttle plate open should be 4.5-5.0

If this checks out, your problem is elsewhere. If you get other readings, post em up and I will try and help you further

Good luck!

 

just rember the cover!

 

In what setting do you move the **** to test the TPS. I think mime be going out too [:@]

 

****, I don't remember, I think just as shown in the pic

 

Yes put it on DCV, 20 volts, since you're measuring a voltage between 0 and 5 volts. Many meters will select the range automatically and you just have to set it to DCV.

 

Thanks buddy [&:]
