R34 Gtr Tps / Throttle Position Sensor - Constantly At 4% On Idle

[iwanta34gtr]

Hi Every1,

On the MFD in my R34 GTR, the throttle reading is constantly at 3 - 4% on idle.

It has been doing this since a mechanic told me that my TPS was 'in the incorrect position' and put it in the right position.

I'm trying to figure out whether should I simply put the TPS back the way it was (so i get 0% on idle again) or whether my TPS is faulty and I need to buy and install a new one?

Is there anything else that could be causing the 4% reading on idle? Does it have to be calibrated?

Any info or advice is appreciated.

Thanks.

Probably just need to calibrate it - stole these instructions off the net.

Calibration of throttle position sensor 1) Turn the key to the "OFF" position 2) Press and hold

"RETURN" and "MODE" switches on the MFD at the same time. 3) Turn the key to the "ON"

position while still holding down the "RETURN" and "MODE" switches 4) When the opening

screen with the"GT-R logo" appears, release the "RETURN" and "MODE" switches, and click the

joystick 5 times within the next 3 seconds. 5) Set the throttle gauge calibration

You can also loosen the tps and rotate it slightly, but I think calibration is the go. You'll probably find that if you put it back so you get 0% at idle, you will only get 90-something percent at full throttle.

Thanks mate, thats spot on.

Found similar instructions in the service manual last night and gave them a go this morning - throttle now sits at 0% as desired.

Thought i'd screen print and post the instructions incase they are needed in the future.

Thanks for your quick reply and help.
