Question about 1996 Volkswagen Passat
Engine wouldnt rev past 5000 rpm. diagnostic showed hall sensor fault. put 2nd hand one in- worked ok at first then woulnt rev past 1500 rpm
It "might" be your throttle position sensor, look for some electronic's going into your or near your throttle body and clean them with disc brake cleaner, something that won't leave a film on it.
This was the problem with my chevy, I know it not the same car but it's worth a try, cheaper that replacing it.

when you are looking at the engine pull off the plastic cover on top then the front cover that covers you timing belt there is a wire harness tha goes right to it in the left upper coner two ten mil bolts and it comes off careful not to drop bolts down in belt that could be bad. it is that easy

this a map sensor, probably just need the sensor replaced, it measurese intake vaccum and adjusts air/fuel mixture accordingly

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
