Fault codes
Code 2.5, SID 21 / SPN 636
Engine speed sensor, camshaft
Reason:
•
No signal.
•
Abnormal frequency.
•
Fault in sensor.
Reaction:
•
Engine takes longer to start than normal. Engine
runs normally when running.
Action:
•
Check that the engine speed sensor connector is
correctly installed.
•
Check that the wiring to the engine speed sensor
is not damaged.
•
Check that the engine speed sensor is correctly
installed in the upper timing gear cover.
•
Check engine speed sensor function.
Code 2.6, PID / SPN 190. Engine speed
Reason:
•
Engine speed too high.
Reaction:
•
None.
Action:
•
After the engine has stopped, look for the reason
for the high speed.
Code 2.8, PPID 132 / SPN 608 Engine speed
potentiometer connected to CIU
Reason:
•
Short circuit to positive (+) or earth (ground) (-).
•
Fault in sensor.
Reaction:
•
Engine goes to idle.
•
rpm is frozen.
Action:
•
Check that the potentiometer is correctly con-
nected.
•
Check that the potentiometer cable is not dam-
aged.
•
Check potentiometer function.
Code 2.9, PID / SPN 97
Indicator for water in fuel
Reason:
•
Short circuit.
•
Open circuit.
•
Fault in indicator.
Reaction:
•
None.
Action:
•
Check the indicator cables for breaks and short
circuits.
•
Check indicator function. Change indicator as nec-
essary.
Code 3.1, PID / SPN 100. Oil pressure sensor
Reason:
•
Short circuit to positive (+) or earth (ground) (-).
•
Open circuit.
Reaction:
•
None.
Action:
•
Check that the potentiometer cable is not dam-
aged.
•
Check that the oil pressure sensor is correctly
connected.
Code 3.2, PID / SPN 105
Charge air temperature sensor
Reason:
•
Short circuit to positive (+) or earth (ground) (-).
•
Open circuit.
Reaction:
•
None.
Action:
•
Check that the charge air temperature sensor con-
nector is correctly installed.
•
Check that the charge air temperature sensor
cable is not damaged.
•
Check that the charge air temperature sensor is
correctly installed.
•
Check charge air temperature sensor function.
