1991 accord lx TPS specs?

I need the specs/ correct adjustment for the TPS Sensor? The paper that was with the part stated that:

I needed to volt test the 2nd and 3rd connector, by piercing through the wires on the TPS connector.

It says:

0.5volts when the throttle body is closed.
4.5volts when the throttle bosy is fully open.

I did this and i got 4volts when closed, and 1 when open. No adjustments changed these readings..

I then watched a video and a guy said you check the OHMs between the 1st and 2nd wires, or bottom two.. and the reading should be between
.5000-.9000 Ohms.
Does anyone know what is correct? where do i find adjustment info?

Re: 1991 accord lx TPS specs?

IIRC you need to pre-load the TPS sensor (rotate the TPS shaft 180) before you put it into the throttle body. The two wires that you are probing should be the signal wire (+ RED/BLK??) and the ground wire (- GRN/WHT??).

The specs are approx. 0.45v - 0.5v closed throttle and 4.5v - 5v wide open throttle. I've never used resistance so I'm not sure what the specs are using that test procedure.
