How the hell do you change the Trottle Position Sensor on an F22??? I got a replacement TPS and when i checked mine out to remove it i was like wtf? theres no where to unscrew it from ? any input would be highly appreciated

 

You have to take a screwdriver and kinda scrape it out it a *****

 

Here is a quick DIY on how to remove those pesky no head shear bolts from your TPS.

Before removing the bolts from the TPS make sure to mark it's position with a permanent marker or scratch a line from the TPS mount to the throttle body to ensure that it will go back in the same place as it was set from the factory. May save a TPS adjustment headache in the long run

First grind of the little nipple that sticks out of the top of the "rivet" screw. This will allow you to have a flat surface to cut into.

This is the nipple that you want to get rid of.



Second with a hack saw blade or dremel cutting wheel you want to cut a line in the head of the rivet. Like so....



Cut the line as close to the TPS mounting surface as you can. This will allow for more contact surface for your flat head screwdriver. Also insure that you cut it wide enough to fit a decent sized flat head....



Once you have it cut deep enough insert the flat head screwdriver and turn counter clockwise.



Voila.....



This job is much easier with the TB removed from the intake manifold

Don't forget that once you have the TPS loose on the car you will have to make sure that it is adjusted properly with a multimeter or voltmeter. This is to ensure that you are getting the proper readings at closed (approx. 0.5v) and wide open throttle (approx. 4.5v)

Cheers and good luck

 

how exactly do you adjust ???? thanks for the info real big help

Resistance check - With the TB closed, sensor disconnected, ign off:
Pins 1 and 2 = 0.5-0.9ohms
Pins 2 and 3 = 3.6-5.4ohms

Voltage check - You need to be sure you have correct voltage, sensor connected, ign 'on':
Pins 1 and 3
0.5volts with the TB closed
4.5volts with the TB fully open</TD></TR></TABLE>

Above when he mentions moving the TPS around he means rotate it as it sits on the TB clockwise or counter clockwise until you have your multimeter reading 0.5v @ closed throttle. Tighten the bolts and push the throttle Wide open and make sure you are getting approx. 4.5v. Keep adjusting the TPS until you are within these voltage ranges.

 

Anyone know what size bolts you will need to replace the studs you remove?
