Mercedes A160 NON Start DTC 2332

Hi Guys,

I'm looking for any common engine loom chafing points on the above vehicle, I have a intermittent non start triggering a DTC 2332 (sensor circuit 3 low voltage) along with a cam sensor fault, we have looked at the obvious but cant get it to falter whilst in the workshop.
Anyone with any Mercedes experience regarding this vehicle would be good to hear from.

Thanks in advance.
Mark
