VW Amarok does not start

I have a VW Amarok that has no injection pulse, or feeding in the preheater is Diesel Cammon Rail, I have a P0651 Code Reference Sensor High Voltage Reference Sensor

I hope this data serves you. Fuente Translate.google.com.ar/translate?hl=en&...ult.aspx&prev=search
Greetings

What does this mean?
OBD P0651refers Code to
these 5 volt reference circuits are independent of each other outside the PCM, but they are searched together inside the engine control module (ECM). Therefore a circuit condition in a reference circuit of 5 volts of the sensor can affect the other reference circuits of 5 volts of the sensor. The ECM controls the tension in the 5 volt reference circuit.
Causes
The possible causes of Code OBD P0651
- Sensor Short - Sensor Circuit in Short - ECM FAILED The error code is generally active in the detection of the following conditions: the ECM has detected an out of the voltage range in the reference circuit of 5 volts 2

If that knew, the issue is that can cause me not to have injection and feeding pulse in the preheater?

When this voltage variation the injection is inhibited as protection.
It can be for a burned transistor in the module.
As far as I know, it was a very common problem in the first ones that came out.
