Boost Pressure Sensor (Code 3.4, PID/SPN 102/106)
Cause Reaction Remedy
• Short circuit to positive (+) or
earth (ground) (–)
• Open circuit
• Engine smokes more than
normally during acceleration/
load increase
• Check
that the boost pressure
sensor connector is correctly
installed
• Check that the boost pressure
sensor cable is not damaged
• Check that the boost pressure
sensor is correctly installed
• Check boost pressure sensor
function
Boost Pressure Sensor (Code 3.5, PID/SPN 106)
Cause Reaction Action
• High charge pressure • Engine power is reduced or
engine stops.
• Check that the charge air
pressure sensor connector is
correctly installed
• Check that the charge air
pressure sensor cable is not
damaged
• Check that the charge air
pressure sensor is correctly
installed
• Check
charge air temperature
sensor function
Air Filter Pressure (Code 5.5, PID/SPN 107)
Cause Reaction Remedy
• Too large pressure drop
across filter
• Less good response from
engine
• Check the air filter
Air Filter Sensor (Code 5.6, PID/SPN 107)
Cause Reaction Remedy
• Shorted to plus (+) or minus
(-)
•
Break
• None • Check
that the air filter sensor
contact is correctly installed
• Check that the cable harness
to air filter sensor has not
been damaged
• Check the air filter sensor
functionality
