Throttle position sensor (setting up)
Hi all,
i was testing the voltage on a few sensors on my 1995 wrx and the throttle position voltage was out,
So i set it to 4.7v off throttle and 0.9v full throttle as the manual said (is this correct ?) but now it's idling ant 1500 rmp.
Is there anyway of lowering it or should i set it back to what it was,
Any advice would be great.

Hi again,
Also if i set it up at full throttle to 0.9v when the throttle is closed it goes upto 5.3v,
With it set a 4.7v closed when its full throttle it goes to 0.4v and give's me code 31 which i think is tps.
Can anybody help?
Or is the tps fualty.

Code 31 is the TPS but if it idles ok @ 5.3v then i would leave it at that unless you have running/idle problems.
You said in your original post that you were checking the engine sensors - did you have a problem at the time or was it preventive maintanance ?
Could be just a case of - if it aint broke,dont fix it.

I was just giving it a once over as i came across this
JollyGreenMonster.co.uk
So i thought i would check a few things out,
But seems to run ok other wise, can be a little rice on full throttle sometime's as it dumps a bit of black smoke out the exhaust.
