If it is not I the correct position it will return an error code , not only if it is faulty.. have a crack at this b4 shelling out on a new one..

Insert a jumper pin between the ten and gnd pins. turn on the ignition (don’t start) loosen the tps bolts rotate it until the cooling fan comes on (or alternatively till it goes off) what you are looking for is the point that the fan goes off at .. when you find it tighten the tps bolts. Switch off the keys, remove the jumper ..

Or if you want to do it by the book, and set every thing……..

How to set idle/TPS and timing on the V6

Start the car, let it warm up,

You NEED a timing light, Without the timing light none of this will work.

Insert a jumper pin between the ten and gnd pins. Hook up the timing light to the battery for power and hook up the signal to the #1 wire location on the disty(make sure all 6 plugs will still get full spark). Loosen the two 12 mm bolts on the disty so it can rotate(not too loose). Now, with the jumper pin inserted, start the car, if it dies, then open the idle air screw on the top of the tb a couple turns.

Make sure the car is warmed up, NO accessories or fans or anything is on, and if the idle is like 1500 then close the idle air screw a little, it should be open 2-3 full turns. Now, move the power steering hoses and wires out of the way, point the flashing timing light at the crank pulley, and watch the small tab on it illuminate and reference it's location to the small timing marks on the plastic tab that sticks out over it. Rotate the disty until the notch on the crank pulley is exactly in line with the "10" on the plastic timing mark indicator(this is 10 degrees before top dead center). Now when it's at 10, tighten the disty down carefully so as not to move it. Double check for 10 deg. btdc. Now adjust the idle air screw until your idle sits right at 650 rpms (+/-25). Turn off the car, remove the jumper pin.

Do not adjust the idle air screw unless the car is running with the ten/gnd pins jumped!!!!!

Now, get your voltmeter. Set it to ohms. Touch the two terminals on the idle air bypass control valve(black part on bottom of tb). The resistance should be 10.2-12.3 ohms. If so, then that is ok. Unplug the TPS, with the voltmeter still on ohms (or continuity check mode), touch the two lowest pins with the terminals of the voltmeter. There should be continuity. If not, loosen the two screws holding it so you can just rotate it, and rotate until you get continuity. Next, take a .006"(.15mm) feeler gauge, and put it between the throttle stop screw and the throttle linkage(back/top of the TB) Before doing that, make sure that the stop screw that the linkage hits JUST barely touches it at closed throttle.(2.5mm allen key wrench for it). Now with the feeler gauge inserted, there should still be continuity, if not, rotate until there is. Next, switch to a .020"(.50mm) feeler gauge in, there should not be continuity, if so, redo the previous step until it is correct.
Plug the sensor back in, turn the key to the on position with a paper clip jumping the ten and gnd pins.Now measure volts, and put the black from the voltmeter on the neg. terminal of the battery, and tap into the yellow(2nd wire down from top of tps harness). Voltage should be between .1 and 1.1 at closed throttle, but I found .5 to be perfect. At wot it should be 3.6-4 volts(check by pressing gas pedal to ensure it opens fully).
Now start the car, your idle will be perfect.
