s14a revs up when turning the steering wheel??+

[blackss13]

as the tittle. everytime i turn my steering wheel the revs go up slightly. anyone can shine some light??

I'm going to make a guess here - power steering pump is engine driven, turning the wheel works the pump which puts a little extra load on the engine so the idle control valve compensates for this by increasing the revs slightly.

I agree with that, mine does it too

Spot on Chris.

There's a sensor in the PAS circuit that makes the IACV up the idle when the wheel is turned.

Same (ish) if u try to close an already closed leccy window, or at least my idle fluctuates very slightly...
