OK, Lets get you straightened out
The Camshaft sensor provides data to the Engine Management Computer (ECM). The ECM uses that data for many things, one is to properly position camshaft timing through the Camshaft, Solenoids and Phasers. The Phasers are adjusted via the phaser solenoid (VCT), which operates using Oil Pressure.
With the camshaft sensor not working, the ECM would not be sending a signal to the (VCT) and therefore adjusting the Phaser. Once you replaced the camshaft sensor, the ECM was able to signal the (VCT) and therefore adjust the phaser.
That is when you discovered you had a faulty camshaft Phaser (Typical Noise), or .... Low oil pressure causing the Phaser not to operate properly....
Since you need to go into the engine to have the timing assembly replaced. There are some things to consider.
1- Aftermarket parts don't work well with the 5.4L engines, to assure effective repair, use OEM parts (I learned this the hard way, and had to tear the engine down (again) because the aftermarket chain guide broke)
2- Verify your cam lobes and rockers on your passengers (Right) side are not damaged. If the timing chain tensioners are leaking then its highly likely your Right side cam shaft is damaged, especially near the firewall.
3- It's also recommended that you replace the oil pump with a High Volume oil pump when you replace your timing assembly.
At your mileage, I would suggest performing a cylinder compression test. If that test is low or borderline... Its time to Consider a complete engine rebuild... Its far easier to replace the timing assembly if the engine is out of the vehicle, trust me I have done this job. If you need to replace a worn camshaft and worn rockers, due to oil pressure loss from leaking cam chain tensioners, along with other timing components. My suggestion would be, pull the engine and go through it.
Crate engines (long block) range from $3000 to $4600 (Ford), you can easily add another $500 to $1500 for incidentals, such as gaskets, water pump, Spark Plugs, Plug Coils, Injectors, Pressure regulator, Oil and Air filters, oil, coolant etc. Plus you will need to "core" your old engine if you go this route.
Go to You tube and listen to faulty 5.4 phaser noise. Example below...
