Fault codes
PID 102, Code 2.2.3 Charge pressure sensor
Reason: Faulty sensor, connector or cable.
Reaction: A fault code is generated.
Action:
• Check the sensor cable for breaks and short cir-
cuits.
• Check sensor function. Change the sensor as
necessary.
PID 100, Code 2.2.4 Oil pressure sensor
Reason: Faulty sensor, connector or cable.
Reaction: A fault code is generated.
Action:
• Check the sensor cable for breaks and short cir-
cuits.
• Check sensor function. Change the sensor as
necessary.
PID 110, Code 2.2.5 Temperature sensor, coolant
Reason: Faulty sensor, connector or cable.
Reaction: A fault code is generated.
Action:
• Check the sensor cable for breaks and short cir-
cuits.
• Check sensor function. Change the sensor as
necessary.

PID 174, Code 2.2.7 Fuel temperature sensor
Reason: Faulty sensor, connector or cable.
Reaction: A fault code is generated.
Action:
• Check the sensor cable for breaks and short cir-
cuits.
• Check sensor function. Change the sensor as
necessary.
PID 100, Code 2.3.1 Warning, oil pressure
Reason: Oil pressure below specified limit value (de-
pends on engine speed).
Reaction: A fault code is generated. The fault code
disappears when the oil pressure exceeds the recu-
peration value.
Action:
• Check the oil level and oil pump.
• Check the sensor cable for breaks and short cir-
cuits.
• Check sensor function. Change the sensor as
necessary.
• Check the limit value for oil pressure warning.
PID 110, Code 2.3.2 Warning, coolant
temperature
Reason: Excessive coolant temperature
Reaction: A fault code is generated. The fault code
disappears when the coolant temperature falls below
the recuperation value.
Action:
• Check the coolant.
• Check the sensor cable for breaks and short cir-
cuits.
• Check sensor function. Change the sensor as
necessary.
