105 11
Charge air temperature sensor: the voltage of sensor measured by
ECU is out of the target range Check wiring, CAC-sensor not working, check sensor and if necessary replace it, check connection cable
and if necessary repair or replace it.
523613 0, 1, or 2
Rail pressure: the fuel pressure in rail calculated by ECU is either
below or above the target range which is dependant on the engine
speed Check for leakage. Check fuel level in tank and low pressure system. Check fuel-primary pressure. Check
backflow pressure check sensor. Check pressure relief valve. Check metering unit.Check Injector
function (metering unit, injector). If necessary replace components as required.

Fuel metering unit: the ECU detects no load, or the current drain
measured by ECU is above the target range, (Open, Short to B+,
Short to B-)
Check wiring , if necessary check FCU, check fuel metering unit and if necessary replace it, check
connection cable and if necessary repair or replace it
107 0, 3
Air filter differential pressure: the pressure difference of the intake air
between the filter inlet and outlet calculated by ECU is above the
target range

2, 7, 11, 12,
or 14
Rail pressure: Pressure Relief Valve (PRV) error.
Check error memory for other additional errors and eleminate them first. Check working voltage and if
necessary correct it, check PRV opening counter and if necessary replace it, check rail-pressure sensor
and if necessary replace it, check FCU and if necessary replace it, check rail pressure relief valve and if
157 3, or 4
