i herd u could mod you throttle position sencer by drilling somthing for more responce is this tru.has anybody done this.how do you do it.

 

Your a little mislead here....To get more performance you can modify the voltage of the sensor....trust me its not worth the gains...
What your thinking of is if you know your TPS is bad instead of replacing it you can try drilling it out and filling it with Electrical Cleaner....This worked for me and saved me $30, no performance obvisously

 

Take the two mounting bolts out. 1/4" drill bit, and drill the brass fittings out (they will spin within the assembly eventually melting out). Get a couple of larger washers (holes will be bigger than the bolts). Re-install, measuring with key on and turning the TPS untill .70-.75 volts is achieved. Did mine last weekend, took a few minutes for idle to come back to normal. Its hard to tell if it truly helped throttle response. Mine was .57 before the mod, and I guess it has helped a little. Hell it only took about 20 minutes and it didn't hurt anything so...........

 

Smokegrinder, this is a mod and not a repair. What you are talking about is the repair/cleaning. Adjustment of the voltage is to achieve better throttle response. Some people have great gains from this, while others (myself included) see little. Have done this on Mustangs also and have seen very good benefits.

 

i dont really undersyand what is done.i guess ill have to take it off to see what your talking about.it just sound like you make the holes bigger for the bolts. how do you ajust voltage.we'll see.

 

Once the brass rings are out the TPS has room to rotate on the bolts (about a 1/16" in either direction). Rotating ccw increases voltage. If you search this issue on this forum or Google you will eventually find pictures.

 

The mod isnot worth the trouble. The pcm will relearn the limits before you fill up again. As far as repairing a bad tps, I don't know. What makes you think yours is bad?

 

if the pcm has learned the max limit the tps perdueses how do you get more voltage out of it in the first place.doesnt the tps work like a dimmer switch;say it gets a max of 1v sent to it,so it has 1v to work with,the more it turns the more power is going to be sent to the pcm.so at idle .55v, then open the trottle and more power is let thru to .60, .65, .70, .75 and so on, am i geting this right.so if you start out with a higher voltage the better responce.does any body know how this gives you better responce,that is the millon $ qustn.

I wish someone could shed some light on this topic, because alot what I'm reading says that in almost all late model vehicles the PCM relearns at idle startup and sets the reference back to zero. Does anyone know how our trucks PCM learns or adjusts to these mods?
