CID 0320 FMI 02 Speed And
Timing Sensor Intermittent
Loss Of Signal
Conditions Which Generate This Code:
The signal for
the speed/timing sensor is intermittent.
This speed/timing sensor is located near the flywheel
housing.
System Response:
The Electroni
c Control Module (ECM) will use the
speed/timing sensor in the fuel injection pump to
determine engine speed. The ECM will log the
diagnostic c
ode. The diagnostic code may be viewed
on the electronic service tool.
Possible Pe
rformance Effect:
There may be a slight change in engine response.
The ECM will limit the maximum engine speed to
1200 rpm.
If the signal is lost from both of the engine
speed/timing sensors, the ECM will shut down the
engine.
Perform the following diagnostic procedure: “Engine
Speed/Timi
ng Sensor Circuit - Test”
Results:
•
OK – STOP.
•
REPAIRED, O
K–STOP.

CID 0320 FM I
11 Speed And
Timing Sensor Loss Of Signal
Conditions Which Generate This Code:
The signal for the speed/timing sensor is lost. This
speed/timing sensor is located near the flywheel
housing.
System Response:
The Electronic Control Module (ECM) will use the
speed/timing sensor in the fuel injection pump to
determine eng
ine speed. The ECM will log the
diagnostic code. The diagnostic code may be viewed
on the electronic service tool.
Possible Pe rformance Effect:
Theremaybeas
light change in engine response.
The ECM will limit the maximum engine speed to
1200 rpm.
If the signal is lost from both of the engine
speed/timin
g sensors, the ECM will shut down the
engine.
Perform the f
ollowing diagnostic procedure: “ Engine
Speed/Timing Sensor Circuit - Test”
Results:
•
OK – STOP.
•
REPAIRED, OK – STOP.

CID 0342 F M I 02 Sp eed
And Timing Sensor No.2
Intermitte
nt Signa l
Conditions Which G enerate This Code:
Note: If bot
h of the following diagnostic codes are
active, then the fuel injection pump has suffered a
complete failure of the electrical supply:
•
0174-02
•
0342-02
Both of the diagnostic codes will be active if there has
been a comm
unication fault between the Electronic
Control Module (ECM) and the CAN data link for the
fuel injection pump. If only the 0342-02 is active there
is not a fau
lt with the electrical supply for the fuel
injection pump.
The signa
l for the speed/timing sensor in the fuel
injection pump is intermittent or lost for less than one
second.
