Hello and welcome to JustAnswer!
These codes could be caused by wiring or connections but it's unlikely. The most likely cause would be the valves sticking, being broken, or the actuators.
The first step would be to ensure the powertrain control module software is up to date. There was a software revision specifically for the P1004 setting.
After the software is up to date then the actuators should be actuated with scan tool to see if their duty cycle is correct when open and closed. If not then a problem is still present.
At that point the actuators are removed. If the valves bind when moving them by hand then the intake is replaced, if the valves move freely then the actuators are replaced. If you're positive the valves are ok then I'd recommend making sure the software is up to date, and then replace the actuators.
