Hey Mr.Nickleye?

I know I'm not Mr.nickleye, but I can offer some info.

First, you can buy a multi-meter which can measure ohms, volts and amps. You can get a cheap one from any parts store for about $15. Home depot sells better ones for around $50. And yes it is a necessary tool for diagnosing electrical circuits.

You are correct about adjusting the sensor. Mr.Nickleye was not wrong. Think about it, the sensor has eccentric holes, you think you can just slap it in at any spot? Here is the TSRM way of adjusting a throttle position sensor on a 7M-GE (7M-GTE's clearances are different).

Looking at the TPS terminals from top to bottom the terminals are labeled E2, IDL, VTA, Vc. Top to bottom.

Put the sensor on the throttle body and put the screws in but dont tighten them all the way.

As you stated put a .58 mm (.0228 in.) feeler gauge between the throttle stop screw and lever and connect an ohm meter to terminals IDL and E2.

Now turn the sensor clockwise until the there is infinite resistance shown on the ohm meter. Thats the jap to english conversion of deflect. They also call grounds- earth, not a good translation for the TSRM.

Now tighten the screws, and check resistances. With a .40 mm (.0157 in.) feeler between lever and screw there should be less than 2.3k ohms between IDL and E2. With a .75mm (.0295 in) feeler there should be infinite resistance between IDL and E2.

Then check the resistance with no feeler gauge between termianls VTA and E2. It should be between .3-6.3k ohms.

And with the throttle fully open resistance between terminals VTA and E2 should be 3.5-10.3k ohms.

Hope this helps.
