ive got a problem with a cossie, the idle valve stays open all the time as soon as you start it hot or cold ive tryed the valve on another car and it works fine, ive just fitted a l8 ecu to a 2wd car and since then its been like it ive tryed swapping the wires back on the tps and another map sensor and no difference also when you touch the throttle the amal valve clicks on then clicks off when you close the throttle.

any helpers?

tps setting correct?

and is it a pf09?

deffo sounds like a tps issue to me

yep pf09, tps seems to be in the right place.

check the wiring, and its calibration needs to be checked before you go much further, also check its sweep,

common issus are broken wires, shorted wires, broken plugs, knackered tps,

if the ecu sees an open throttle it will open the iscv, and an incorrectly set tps can make the amal and iscv go ape

if you disconect the tps plug the amal valve clicks on but the revs still stay high???

ign on and test which pin is live at the iscv


then disconnect your ecu, and run a continuity check between the other pin and earth, shouldnt be grounded, if it is it has a dead short in the loom.

make sure you check the tps calibration/wiring aswell!

i think the calibration is right im sure its got to be the wiring to it, might be new loom time...
