Question?? 06 LBZ keep getting 003a code, but only after driving and cooled down a day or so, I clear code start it up and can hear the turbo whistle, should I be going after the vane position sensor? Any help is appreciated

Do you have something to monitor vane position with? Could check the position and make sure it's doing a full sweep on start up and reading properly. Probably needs the cover taken off and clean out the crud on the vanes and ring

I only have an older obd2 scanner and no programmer, the only good data was fuel rail pressure, the truck is completely stock 242k miles, I was thinking of pulling the sensor and cleaning it first ??
