SID22, Code 2.5 Speed sensor, camshaft wheel
Cause:
No signal.
Abnormal frequency.
Sensor faulty.
Reaction:
The engine takes longer than normal to start. En-
gine runs normally when is running.
Remedy:
Check that the speed sensor contact has been in-
stalled correctly.
Check that the cable harness to the speed sensor
has not been damaged.
Check that the speed sensor was installed cor-
rectly in the upper timing gear cover.
Check speed sensor function.
Check contact pressure in socket 45 and 46 in
the upper cable glove (A) to the engine control
module.
PID 190, Code 2.6 Engine rpm
Reason:
Rpm too high.
Reaction:
VE engines: None.
GE engines: Engine is shut off (unless the protec-
tion has been shut off with the parameter setting
tool).
Remedy:
When the motor stops, look for the cause of high
rpm.
PPID 132, Code 2.8 RPM-potentiometer
connected to CIU
Reason:
Shorted to plus (+) or minus (-).
Potentiometer faulty.
Reaction:
VE engines: Engine goes to idle.
If you release the accelerator first, and the press
it down again, the engine can be forced to run us-
ing the idle contact.
GE engines: Engine speed is maintained.
Remedy:
Check that the potentiometer has been connected
correctly.
Check that the cable harness to the potentiometer
has not been damaged.
Check the potentiometer function.
PID 97, Code 2.9 Indicator for water in fuel
Reason:
Short.
Break.
Dial indicator faulty.
Reaction:
None.
Remedy:
Check the cable harness to dial indicator with re-
gard to short and break.
Check dial indicator function. Change indicator as
necessary.
PID 100, Code 3.1 Oil pressure sensor
Reason:
Shorted to plus (+) or minus (-).
Break.
Reaction:
None.
Remedy:
Check that the cable harness to the oil pressure
sensor has not been damaged.
Check that the oil pressure sensor has been con-
nected correctly.
Check contact pressure in socket 11 in the lower
cable glove (B) to the engine control module.
