Oil Level Sensor (Code 5.9, PID/SPN 98)
Cause Reaction Remedy
• Shorted to plus (+) or minus
(-)
• Break
• None • Check that the cable harness
to the oil level sensor has not
been damaged
•
Check the oil level sensor
function
Oil Pressure Sensor (Code 3.1, PID/SPN 100)
Cause Reaction Remedy
• Short circuit to positive (+) or
earth (ground) (–)
• Open circuit
• None • Check that the oil pressure
sensor cable is not damaged
•
Check that the oil pressure
sensor is correctly connected
Oil Pressure (Code 6.6, PID/SPN 100)
Cause Reaction Remedy
• Oil pressure is too low • Engine control module
reduces engine power
(unless the protection has
been shut off with the VODIA
diagnostic tool)
• Check oil level
• Check that the air filter is not
blocked
• Check system pressure
valves and safety valves in
the oil system
• Check oil pressure sensor
function
Boost Temperature Sensor (Code 3.2, PID/SPN 105)
Cause Reaction Remedy
• Short circuit to positive (+) or
earth (ground) (–)
•
Open circuit
• None • Check that the boost temper-
ature
sensor connector is cor-
rectly installed
• Check that the boost temper-
ature sensor cable is not dam-
aged
• Check that the boost temper-
ature sensor is correctly
installed
• Check boost temperature
sensor function
Boost Temperature (Code 6.2, PID/SPN 105)
Cause Reaction Remedy
• Boost
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 boost temperature
sensor function
• Check the function of the ther-
mostat
