I'm trying to adjust the tps on my 90 TII, but I can't figure out which pins to measure the resistence between. The connector to the tps (both sensors go into one plug) looks like this;

----^---
| x x x |
| x x x |
---------

which pins do i connect the ohmmeter to?

 

Follow the three wires from the narrow range TPS to the connector. Connect to those wires. Your common probe will go on the "middle" wire, and then your other probe on one of the outer wires. If you find that resistance DECREASES when you open the throttle, switch to the other outer wire.

 

Thanks, that did it. And if anyone else is wondering it turned out to be the pins represented by 0s below;
---^---
| x x 0 |
| x x 0 |
---------

 

It's the black and green one.
