Introduction
The following procedure is for troubleshooting the SPN 190 FMI 0 engine overspeed vehicle event
fault.
Introduction
NOTICE
To prevent engine damage, do not attempt to start the engine until a
full engine analysis and all diagnostic steps have been completed.
The following fault can be set when the vehicle is in motion and engine speed reaches 2600 rpm with
no fuel being requested by the Engine Control Module (ECM). When set, this DTC will illuminate the

Red Stop Engine Light (RSL) and the Malfunction Indicator Lamp (MIL). Once the vehicle is at 0
mph, the ECM will initiate a protection strategy. The Engine Throttle Valve (ETV) and Exhaust Gas
Recirculation (EGR) valve will close, and the fuel injectors will be disabled. The Fuel Pressure
Control Valve (FPCV) will open to relieve fuel rail pressure in case of injector tip damage. A
complete engine analysis must be completed to assess damage due to excessive engine speed, prior to
the engine being started.

Note: The MIL and RSL will illuminate when the fault is detected.
Note: Before beginning diagnostics, do the following
• Submit report to Dealer Solutions Network (DSN)
• Take pictures of all damage for failure evidence
• Do not replace any parts until complete inspection has been completed
• Ensure that the calibration is up to date at end of repair
• CAT CT11 and CT13 engines are to follow the same repair path.
Note: CAT CT11 and CAT CT13 parts and SRTs may be different

Note: In the event of other fault codes logged the 190-0 Engine Overspeed Most Severe Level should
be diagnosed FIRST.

Step
Action
Decision
Yes- Go to Step 2
Visual inspection of Turbo
Outlet Pipe
1
Remove turbo outlet pipe
No - Interview Driver
When did the fault occur
Remove CAC outlet pipe
How was the truck operating when the fault occurred
Is there excessive oil
coming from the highpressure turbocharger(HP)
Save Freeze Frame Data from 190-0 fault code
Visually inspect external
engine block for damage
2
Save Vehicle Trip Report
Submit Case File to DSN and attach the Vehicle Trip Report,
Freeze Frame Data, and the answers above.
Yes -Document damage with pictures. Open a DSN report for
complete engine, block, or crankshaft replacement. DSN
report is located on the vehicle information page, DSN tab.
Attach freeze frame data and pictures to case file DSN report.
Has engine block damage
occurred?
No-Go to Step 3
3
Connect to Engine Control
Module (ECM) using
personal computer (PC)
with engine diagnostic
software.
For RPM's ranging 2600 to 3200, Go to Step 4.
Open Vehicle Trip report in
engine diagnostic software
Reference PID 58071 Trip
Maximum Engine Speed.
For RPM above 3200, Go to Step 5.

APPROVAL FROM TECH SERVICES
Verify that oil has not reached the Diesel Oxidation Catalyst
(DOC). If the DOC and DPF need removed to drain (Refer to
UENR1845 and UENR4926 for the correct procedure). A
DSN will need to be started if damage has occurred. Location
of the DSN is on the Vehicle Information Page, DSN Tab
Reinstall oil pan and refill (Refer to UENR1845 and
UENR4926 for the correct procedure).
Replace all six injectors (Refer to UENR1845 and
UENR4926 for the correct procedure).
Replace Turbo Center Section (Refer to Special Instruction
REHS9168 for procedure).
Clean Charge Air Cooler (CAC)(Refer to REHS9180)
Proceed to Step 6.
For RPM above 3200
Drain oil and remove oil
pan.
