I agree. P0011, “Intake Camshaft Position (CMP) System Performance” could be caused by a few things, including a gummed up cam phaser, but it seems the solenoid valve is the most frequent culprit and replacing it usually works.
How’s the oil change history on this car? Debris or oil gunk in the valve can cause this problem. This is a rationale for replacing both the intake and exhaust solenoids, two different part numbers. You might consider first running some SeaFoam or something for a few miles and then doing an oil change.
For some strange reason a lot people call the solenoid valves “sensors.” This confusion result in a lot of replacing the wrong part.
The link you gave in the OP is the wrong part.
That’s a camshaft position sensor. Your car has two of them. They rarely fail.
The parts you need look like this -
The one with the pale top is the intake.
Intake AC Delco 12679099 Exhaust AC Delco 12679100
GM's over long descriptive name nomenclature is to blame.
They muddle the part names which simply put would be : sensor, valve, actuator. They mix and match the words in an attempt to be specific and just confuse.
Mission accomplished. Changed out both of them. Tuff little buggers at first. Code erased and didnt come back after the first trip. Oil changes are frequent. I write down the mileage and never go past 4500 miles. Usually its changed around 4000 miles. Valvoline full synthetic and a Wix filter. Next project are the front wheel bearings. Bought them at Rock Auto. The high priced NAPA bearings didnt last very long. Left side lasted about 10k is all. The cam Actuators were Cloyes brand.
The phaser in Ford speak is the Variable Valve Timing Actuator in GM speak. Which gets confused with Variable Valve Timing Actuator Control Solenoid Valve and the Variable Valve Timing Actuator Cam Shaft Position Sensor. Sometimes they add or subtract or rearrange the words.
Unfortunately, some/most people can only get through 2-3 words of a name.

Look up the name of the hold down bolt in the military manual. Yikes.
