Plain-English Meaning
The International A26 ECM monitors engine speed and initiates fuel cut when speed exceeds the calibrated overspeed limit. SPN 190 FMI 0 is the recorded overspeed event. On International LT and RH Series trucks, this commonly results from a missed downshift in manual mode, an Eaton Endurant or UltraShift missed shift on a grade, or a load drop event during PTO work on vocational HX Series trucks. ServiceMaxx stores a fault event record with the peak RPM and vehicle speed at the time the overspeed was detected. Reviewing this data is the first step to distinguish between a driver-caused event — downhill grade in wrong gear — and a mechanical event like a transmission shift failure or engine speed sensor fault. In fleet operations, JPRO can aggregate overspeed event counts across multiple International trucks to identify route- or driver-specific risk patterns.
SPN 190 FMI 0 is Engine Speed above normal range. ServiceMaxx provides event fault data including peak RPM and gear state at the time of fault. JPRO also provides fault data for fleet review.
Common Symptoms
- Stored fault — driver may have noticed a sudden loss of throttle response when fuel cut activated
- Possible companion fault codes from the Eaton Endurant or UltraShift transmission
- No active symptom after the event in most cases once engine speed returned to normal
- Recurring events may cause noticeable hesitation pattern on specific grades or routes
Possible Causes
Possible causes may include the items below. The list is not a parts diagnosis.
- Missed downshift in manual mode on a descending grade — driver selected insufficient braking gear
- Eaton Endurant or UltraShift delayed or missed shift allowing RPM to exceed the protection limit
- Load drop during stationary PTO operation causing engine to rev freely
- Inadequate Jake brake or engine retarder engagement on a sustained grade
- Engine speed sensor fault providing a brief false high-RPM reading to the ECM
First Checks
- Connect ServiceMaxx and open the fault event snapshot — note the peak RPM, vehicle speed, and gear position logged at the time of the fault
- Check for companion Eaton Endurant or UltraShift transmission fault codes that may have preceded the overspeed event
- Discuss operating conditions with the driver — identify the specific grade, loaded weight, and gear selection mode in use at the time
- Review the International LT or RH Series Jake brake/retarder calibration in ServiceMaxx to confirm it is configured for the application's typical grades
- If the event is a first occurrence with no companion faults, document and monitor — a single event from a grade descent does not require component repair
Can I Keep Driving?
Typically no immediate impact. Investigate if events are recurring.

FAQ
Does SPN 190 FMI 0 on the International A26 require a dealer visit?
A single isolated overspeed event is typically a driver or route event and does not require immediate dealer service. The ServiceMaxx fault event record provides the data to make this judgment — if peak RPM was only slightly above the protection limit during a grade descent, no mechanical action is needed. However, if the code is recurring, or if companion transmission fault codes appeared at the same time, ServiceMaxx diagnostics at an International dealer are recommended to confirm no underlying mechanical issue is contributing.
What transmission does the International A26 typically pair with?
The International A26 commonly pairs with Eaton Automated Transmissions (UltraShift or Endurant) or Allison automatics depending on application. For the LT Series highway truck, Eaton Endurant is a common pairing. Missed shift events on a grade are the most common source of overspeed events with automated manual transmissions.
Can repeated overspeed events damage the International A26?
Occasional brief overspeed events handled by the ECM fuel cut are generally not mechanically damaging. However, repeated severe overspeed events �?particularly those sustained long enough for valvetrain inertia forces to be extreme �?can increase engine wear over time. Fleet monitoring of overspeed frequency is a useful indicator of driver behavior or route risk.
