Orange engine light comes on after idle at lights

[NVE_069]

my old car used to do that changed the oil an did come on again
either that or toped it up either way it was fine after that

vaccuum hose

the hose that i think runs from the the throttle body and goes along to the top of the motor, it's the vaccuum hose so you'd hear the leak anyway

mine used to do that was throtle position sensor
25 bux all good

I am getting the orange light sometimes, usually after light throttle periods. Fault code comes up as #19 - Throttle position sensor stuck open.
I removed it to try and clean it, but it's sealed. Holden said $92 for one :bang: - where did you get yours?
