I have a 2003 vw Jetta GLI that has a check engine light on. I am getting 3 codes from it

1: P1347 Volkswagen - Bank 2 Camshaft Position/Crankshaft Position Sensor Wrong Allocation

2: P0346 Volkswagen - Camshaft Position Sensor Intake Circuit Range/Performance Bank 2

3: P0102 Volkswagen - Mass or Volume Air Flow Circuit Low Input

I am pretty sure the maf sensor is unrelated to the other two codes.

My question is do you think I could just change the camshaft position sensor and fix the problem? Also where is the BANK2 camshaft position sensor located on a 2003 vw Jetta GLI? And how do I find it, remove it, and replace it? Thanks.

Vehicle: 2003 Volkswagen jetta GLI 2.8 L V6 turbo

These codes are all related, Without a cam signal the engine timing goes out of range, and the MAF is seen as low voltage input, (ECM does not see it). P0346 camshaft position sensor  "A" circuit bank 2. The "A" is the reference voltage, The camsensor refernce voltage has to be at least 4.5 volts with key on engine off,  If voltage is present replace the camshaft sensor.
