Need help recalibrating my TPS.
I'm swapping my old TB out for a S2 TB, so now I'm lost as to which two pins I should measure to get the recommended OHMs??? I'm doing this with the TB off the car. So it should read in OHMs, not volt.
I saw the clip on youtube where the guy did one on a D16 Civic. He was measuring the TPS OHMs while the TB was off the car. He used the two voltmeter probe to measure the TPS, but he didn't state clearly about which two pins should be touched to measure.
There's three wires, so there's three pins inside the TPS.
Which one do I touch to get the measurements? I heard Honda recommended 500-900 OHMs. The guy from S2 set his at 850ish OHMs.

Re: Need help recalibrating my TPS.
NVM I got it.
The center wire which is red/blk is the one that sends signals back the ECU, so that one will be my main focus. All I have to do is ground one lead on the chassis somewhere and use touch the (+) lead to the pin on the TPS (should be the center pin) and measure the voltage. Rotate it until it reads .5 volts, then tighten it down. Have a friend press the gas pedal to the floor and also check that WOT reads 4.5 volts.

Re: Need help recalibrating my TPS.
This is what I'm really looking for. How to adjust the TPS with TB off the car. :D
Here is how I calibrate my TP sensors with it out of the car. You can calibrate it in the car but you'll need T-pins to backprobe, then you have to tighten the two screws and theres barely room to tighten the screws. I have done it out of the car numerous times and it has been perfect. First familiar yourself with the attachment. You'll need a DMM (Digital Multi-Meter), a spare plug for the sensor or a couple of jumper wires with alligator clips.
1. Bolt sensor onto the throttle body and tighten it to where you can still adjust it.
2. Set your DMM to measure ohm resistance from 1K (1000 ohms) to 5K (5000 ohms). I had mine set at the 20k setting.
3. It doesn't matter which lead goes where but positive lead of DMM to the pin colored in yellow and black lead to pin colored in red.
4. I have measured many TPS resistance this way and I have found that at idle I get a ohm reading of 1.01K and at WOT the reading is 5.36K. Adjust the TPS until you get ~1.01K ohms and tighten the screws. Once tightened go WOT and the reading should be ~5.36K ohms.
In less than 5 minutes you're done and ready to bolt it on the car.
