Just wondering how do you check and adjust it?

 

Cheers

taken from Maciej's website:

 

TPS - Throttle Position Sensor:

Poorly adjusted TPS can cause jumping or high idle. The TPS is located on the left throttle body, pic 2.

To measure its output voltage (if you haven't got a AVC-R or AFC ora Techtom MDM-100) you have to insert a thin wire in its harness contact(pic 2), since it has to be connected while measuring.

Measure between the middle pin and the chassis or battery ground.

The voltage should be between 0.4V and 0.45V (the spec says 0.5V butthat's to high from my experience).

To adjust the voltage, turn ignition switch ON, loosen the screws holding the TPS and turn it slightly (CW => -) until the voltage is within spec. Tighten the screws and recheck voltage.

Open the throttle fully and check that the output voltage is ~4V.

cheers Eric. Should I be able to see this on my Apexi AVC-r?

 

Vijay

Yes, you should see it in the "etc."-menu, under "sensor check" (if I remember the menu name correctly).

 

Cheers for the promotion Eric!

cheers guyz!

 

Vijay

just checked it and it's at .356v. I'm gonna adjust it tomorrow, but what problems would a lower voltage cause?

 

Vijay

I suppose that there would be some hesitation, as

the TPS is leaving the Idle voltage level, later than it should.

 

This is just a guess, as I didn't have that problem myself.
