HELP! Bulletproof, EGR Delete. Pulling an empty 24’ enclosed car hauler. Up a hill at about 70mph and then the dreaded POP! Blew a blue boot off my turbo. Limped about 2 miles, and found the band clamp had broken. (Recent head and injector work. Clamp looked like it had been bent.) Cleaned blue boot connector, new clamp, tightened up and hit the road. ZERO power, literally minimal if any boost. Parked it, ran scan and got a P0046 code. Idles and revs ok, no power. Cleared code, tried again no luck. Weird to think a VGT solenoid would fail at exactly the same time I blew a hose. Any thoughts are much appreciated.

Code P0046 is set when a short to ground, open, or short to power is identified in the VGTCV or wiring between the PCM and VGTCV. This circuit is a continuously monitored circuit that takes less than 1 second to set. First thing to do is to verify that the VGT actuator is fully plugged in and that the connector and wiring are not damaged.
Thank you! Checked plug and wiring, no visible damage on wiring and plug is securely connected. Unplugged and plugged back in. It’s so weird to me that this came up upon blowing a CAC tube connection. I’m back at the house now, limped home. No other codes set aside from P0046. Thank you for you time and wisdom.
