Throttle intake flap BLT

Hi

I keep intermittently getting p2100 throttle acuator control motor / open circuit

I've tired a new ASV and still randomly comes up, on the plug to to asv I've got a battery feed, earth and a 5v feed, but the red/blue wire pin 3 I belive I've got nothing, any one have a wiring diagram or expected value ? Or am I barking up the wrong tree and the Asv isn't related to the throttle acuator control?

Thanks dan
