Ok so reading around the forum i collected this info:
The whole purpose of adjusting the TPS on a 2G is to make sure that the Idle Position Switch inside the TPS is telling the ECU when the throttle is closed.
2G's critical adjustment is the Idle Position Switch that's part of the TPS.
The manual has you place a 0.0177" (0.45mm) feeler gauge between the stop screw and the throttle pulley to open the butterfly and then adjust the TPS right to where the IPS (pins 3 and 4) switches from closed to open.
Then they have you verify that the TPS (pin 2 and 4) reads between 0.4 and 1V while the feeler gauge is still in place.
Anything in that range is ok as long as the IPS is adjusted correctly.
There is no way to adjust the TPS voltage independantly of the IPS on a 2G that I can see. (from Steve)
1. Loosen the 2 TPS screws.
2. Put a feeler gauge of .0177" under the stop screw
3. Turn the car to the ON position
4. Rotate the TPS until pins 3 & 4 lose continuity (open)
5. Verify that the voltage between pins 2 & 4 is .4-1 volt with the feeler still in.
6. Tighten TPS bolts and remove feeler gauge.
7. Verify that the pins 3 & 4 have continuity (shorted) when the throttle is closed and don't have continuity (open) when you open the throttle slightly. (knochgoon24 and Steve)
But still I have some questions!
For this to work properly the SAS (stopper screw) it has to be properly adjusted right?
And how am I supposed to get to the TPS .63v then if I'm only adjusting the IPS e.g if I rotate the TPS until I loose continuity on pins 3 & 4 I'll be way off on the TPS volts even if I'm in the range of 0.4 - 1 volts.
I'm posting this because I'm having some weird problem and I'm pretty sure it's the TPS is the problem. I use DSMlink to simulate but I rather fix it the way it's supposed to be fixed.
Thanks
Oh and one thing more why should I turn the key into on I can check continuity with the car off and the tps unplugged. Right?
Please guys! Anyone? Second thread in a week that I post with not a single answer. Help me out here!
