P1234 002 Pedal value sensor (B96) potentiometer 2; Depending on subcode this can be a high voltage, low voltage supply, or a plausibility between potentiometer 1 and 2.
I would get the subcode. From there you need to check the wiring on the pedal assembly, and the condition of its connector plug. You model uses two physical potentiometers in the pedal. They can wear over time, and be temp sensitive. Dependong on subcode you can test the pedal assembly using a meter, and you can also test the power supply from the ECM.
How many miles/km on the van?
The North american sprinter service manuals have a diagram and pinout for the pedal assembly. It is likely very similar to yours. 2004-2005 models in the USA did away with the potentiometers, and use a optical sensor for longer service life.
On my diesel jetta, the pedal assembly went south at about 200k miles. I cleaned the carbon tracks inside, and got another 10k miles. After which I bought a new pedal assembly.
