as some of you know i got a new TB off a camaro v6-99 on my S1 engine problem im having is with the TPS sensor. at WOT im only showing 85%throttle the blade is open all the way but only showing that amount. When i looked at the TPS i didnt see much range for adjustment anybody else have a remedy or had this problem before??? TIA

Post a pic of the sensor. Is it from the new TB or the old? If it has metal sleeves in it, press them out to make the holes bigger, then put washers under the heads of the screws. That makes a bigger hole to let you move it around. You have to get the low and high ends in at the same time. It can be tricky, and is easier to do off the car.

Where in the throw does it first read 0 and 5%?

I'm thinking the TPS values may be different and you might need to program them into your PCM for it to recognize.

its o % when fully closed, and at WOT its 85%, This is also the sensor from the series TB, The series one TPS sensor dosent fit into the new TB in ANY kind of way so.........i dont have that much matrerial to work with anyway on boring out the TPS but ill give it a shot thanks guys

My concern is if you bore too much.. you might get the 100% at WOT and have 5-10% at idle. Which would end up equally bad.

We always measure voltage through the sensor which is then converted to % of throttle. Somehow I think we could measure resistance throught the sensor. Maybe check the two and see if you have a large difference.
