Have you hooked up an ECU reader? Is there any temp stored codes? Codes can still be stored without an ECU light being on?

[P1112 Port Deactivation Solenoid Valve Actuation Error]

Hello

Thanks for taking the time to read this. I'm having a throttle issue with my vauxhall zafira club 2007, It's intermittent and when it does happen Im experiencing juddering/loss of power. Hooking up an ECU reader i quickly see:

P1112 Port Deactivation Solenoid Valve Actuation Error" (Intake manifold air control actuator - circuit malfunction)

I've traced and found the part, I've attached an image to this post.

Im trying to find the part and replace it, searching for the product numbers or any terms related to the part is coming up blank, can anyone shed any light on this?
