Code P0340 and Code P0344

I have both of these codes on the car I've replaced both camshaft position sensors with the motorcraft ones and I've also replaced the connector for the bank 1 (driver's side) yet the engine light is still on and both codes are on......I need help with any ideas or just an Answer!! Thank you and I appreciate it in advance.

May sound like a dumb question, but did you clear the codes after you installed the new parts? If you didn't, they would still show on your CEL. If you don't have a scan tool that will do that, I believe you can disconnect the battery for a minute then restart your car.

What he said but if the codes reappear and the engine runs rough, the problem could be the VCT solenoids.

I also had that issue. Replaced the sensors and the codes would appear intermittently. Finally, replaced the alternator after reading some posts on this site. Problem solved.
