Fuel guality should have nothing to do with a cam sensor code, but can cause a misfire code.
Depending on the cam sensor code, you may have a faulty exhaust camshaft actuator solenoid.
This part is part of the variable cam timing system.
They can leak oil into the electrical connector, or the screens on the inside of the solenoid.
It is located on the passenger side of the front of the engine, just below the valve cover, near the power steering pump.
