is there another way to adjust the TPS sensor on the TB if it has rivets?

my scan tool has my TP reading at 9.8% at idle and with the pedal to the floor I'm only getting 90.6% is there a way to adjust the TPS if it is riveted into the TB or do I have to get a new TB?

 

cut a slot into the "rivet" and with a flat blade screwdriver, loosen the screws. They are actually threaded like screws not rivets. Or just remove the snap-off screws and replace with some machine screws. The JDM TPS are held on with TORX screws.

 

yea skinnyboy has the idea

what scan tool is that? your numbers are way off.....try going by voltage at the tps, do you have a voltmeter? (and know how to use it)

 

So what should they be? I have a scangauge 2 in the car and it reads 10% at ide. Have to check what it is at WOT.

 

90.6% at WOT maybe the scan tool is just way off I'll check with a voltage meter when I get back form school later tonight.

 

Well Johnny, when the throttle is closed, the throttle position sensor should be reading 0%.

Another thing to note is when you have the throttle fully open is that the tps should be reading 100%.

LOL just kidding around bud

You have either a scan tool that isn't made right for your car, or a bad tps/adjustment.

The tps should read .5v at 0% throttle, and 4.5v at WOT. The ecu will not complain with 0% values between .45v and .55v but your car would run better with it set correctly....

 

On my 97 prelude h22 i too am wondering about my tps. i just replaced my intake manifold gasket. That got rid of my idle roll (with the iac unplugged) but now between 1k and 2100 or so the car is possessed or something. It's not really a miss but more like as if you put the car to the floor and then dumped out of it and put it to the floor again. It does it so bad it will spin the front tires and go into torque steer then dump and do it again. it will do this unless u get it up above 2100 or so. If i plug up the electrical on the iac the car goes into idle roll imediatly. At first i thought it was vacuum related so i tore it down again and went through everything again, even replaced every vacuum line except the one for my brake booster. Still does it. Would a tps cause this or is something else going on? Any help would be greatly appreciated.

 

I figured you were messing with me.

Yes, I know how the tps works and what the voltage readings should be. I am not so sure it should be 0% at idle since the butterfly is not really 100% closed, but is is dang close. The tool I have is a "Scan Gauage 2" which just pluggs into the OBD2 port and is not made for a specfic car so I bet is just reads wrong. Would be nice if you could calibrate it.

Nine - ten at idle and 89 -90 WOT. That was tested with two diffrent throttle bodies so I am sure the TPS is fine, specially since I have no problems and the voltages are correct.

Sounds fine then.

try a different IACV eric....your car will never idle right without it.

 

Its got a brand new iacv on it. I swapped the tps and it cured the surging off idle thank god. It still seems to me that the car is running too lean. I borrowed a friends otc scanner and ran the car on it. It is throwing a knock sensor code and an egr code (which makes since since i have a block off plate under it). Whoever did the motor sway in this car needs to be shot. Every external part on this car ive had to do something to. Exhaust manifold gasket, intake manifold gasket, lower timing cover, tps sensor (which by the looks of it had taken a hard lick) and when i looked for the knock sensor it was broke off the back of the block. So, i'm putting a knock sensor on it today to see if that helps.
