Coolant Temperature Sensor (Code 3.3, PID/SPN 110)
Cause Reaction Remedy
• Short circuit to positive (+) or
earth (ground) (–)
• Open circuit
• Preheating is also activated
when the engine is hot
• Check that the coolant tem-
perature sensor connector is
correctly installed
•
Check that the coolant tem-
perature sensor cable is not
damaged
• Check that the coolant tem-
perature sensor is correctly
installed
• Check coolant temperature
sensor function
Coolant Temperature (Code 6.1, PID/SPN 110)
Cause Reaction Remedy
• Coolant temperature is too
high
• Engine control module
reduces engine power
(unless the protection has
been shut off with the VODIA
diagnostic tool)
• Check the coolant level
• Check the charge air cooler
(cleanliness)
• Check if there is air in the
cooling system
• Check the pressure cap on
the expansion tank
•
Check coolant temperature
sensor function
• Check thermostat function
Coolant Level (Code 2.2, PID/SPN 111)
Cause Reaction Remedy
• Low coolant level • Engine control module
reduces engine power
(unless the protection has
been shut off with the VODIA
diagnostic tool)
• Check the coolant level
• Check coolant level monitor
function
Coolant Level Sensor (Code 2.3, PID/SPN 111)
Cause Reaction Remedy
• Short circuit to positive (+)
•
Fault in sensor
• None • Check that the coolant level
sensor cable is not damaged
•
Check coolant level sensor
function
Crankcase Ventilation Pressure (Code 7.7, PID/SPN 153)
Cause Reaction Remedy
• Crankcase ventilation pres-
sure too high
• The engine is shut down (if
the protection has notbeen
shut
off by the
parameter tool)
• Check whether the crankcase
ventilation is blocked
• Check whether cylinder lin-
ers, pistons or piston rings are
worn or damaged
