Help Setting Tps On R33 S2

[EarthShore]

Searched the forums and couldn't find anything helpful. I was wondering how to set a new TPS to the correct voltages. Sorry guys complete noobie here

[DVS JEZ]

Ignition to on

Using a multimeter set on DC Volts. Connect black probe to an earth point or negative terminal on battery.

-Probe the TPS wiring with the red probe to find the signal wire which shoukd read around .4V, there will be a 12V power and Earth aswell.

-to set the TPS u need the signal to read .4-.5volts with no throttle. If it needs adjusting carefully loosen the tps bolts/screws. (caution these can be tricky to undo, and dont overtighten)

-signal should read around 4.5Volts at full throttle

Theres 2 plugs on the tps, which do I use?

[EarthShore]

Also the battery is relocated to the boot so can I just earth it anywhere on the engine bay?

[DVS JEZ]

Yes earth it on say the strut tower bolt etc.

[EarthShore]

I've set the tps to 0.45V with no throttle and 4.16V throttle down. Is that alright?

[DVS JEZ]

Perfect

Hi guys,

Sorry to hijack this thread

Im Having troubles with my tps

I followed the steps exactly as DVS JEZ described and I cannot measure any voltages whatsoever unsure what supply's voltages to the tps any tips would be greatly appreciated

Also tested with another tps and had the same result

Keen to know if the car has to be running when you do this test or just have the power on?

Also could incorrect voltages cause the car to idle hunt and stall when I clutch in and take my foot off the accelerator

I want to check my tps voltage. If someone can help I have a question. How do I probe the tps wires? I'm not sure where I should be sticking the multimeter

[Ben C34]

Into the back of the plug. Or if your keen into the ecu plug.

Cheers big ears

In case anyone searching cant find it, its the brown plug. The grey is a closed and WOT on-off sensor.

If you adjust it maybe reset the computer afterwords, mine would not idle below 1200rpm until i reset the computer (removed negative lead from battery and held brake pedal for a min and left for another min disconnected).
