331 Injection control pressure too high
Injection control pressure above 25 Mpa
(3675 lbf/in
2
) 2250 kgf/cm
2
Short circuit to earth. Regulator
valve stuck
332
Injection control pressure above
specification with the engine off Sensor signal voltage higher than
expected with the engine off Short circuit to voltage. Sensor
fault
333
Injection control pressure below
best value Pressure does not match the output
signal for a long period of time
Incorrect specification lubricating
oil. Air in the lubricating oil.
Leakage at the ‘O’ ring for the
injector unit. Regulator fault.
334
Injection control pressure does not
reach the correct pressure in the
time allowed
Pressure does not match the output
signal for a short period of time
Incorrect specification lubricating
oil. Air in the lubricating oil.
Leakage at the ‘O’ ring for the
injector unit. Regulator fault.
335
Injection control pressure does not
increase during engine cranking Less than 5,1 MPa (725 lbf/in
2
)
51 kgf/cm
2
after 10 seconds of cranking
Air in the lubricating oil. Fault in
the high -pressure lubricating oil
system
336
Injection control pressure does not
reach the correct pressure
-
A leakage of lubricating oil or
fault in the high -pressure
lubricating oil system
341
Exhaust back pressure signal out
of range - low
EBP device disabled Short, high or low open circuit
342
Exhaust back pressure signal out
of range - high
EBP device disabled Short, high
343
Excessive exhaust back pressure
(gauge)
EBP above working range
Check for sticking EBP valve or
restricted exhaust
344
Exhaust back pressure above
specification when the engine is off EBP signal is higher than expected with
engine off Check for carboned signal line,
biased sensor
351
Change in exhaust back pressure
unable to achieve commanded set
point
EBR below expected at 2300 rev/min
Check for carboned signal line
biased, biased sensor
352
Exhaust back pressure unable to
achieve commanded set point
EBR does not match on KOER test EPR not responding properly
