Diagnose and resolve common sensor failures in International fleets with our guide, designed for technicians to reduce downtime by up to 40%. Includes templates and KPIs for efficient fault management and compliance.
Achieve 95% resolution accuracy for sensor-related faults.
Sensor failures in International vehicles trigger DTCs related to systems like engine, emissions, and transmission. This guide, linked with code structure analysis, helps technicians identify and fix faults efficiently.
Addressing these issues promptly prevents derates, ensures compliance, and minimizes operational disruptions.
| Sensor | Common DTC | Impact |
|---|---|---|
| Coolant Temp | SPN 110 FMI 4 | Engine Derate |
| DEF Quality | SPN 3516 FMI 10 | Emissions Fault |
| Boost Pressure | SPN 102 FMI 2 | Performance Loss |
| Oil Pressure | SPN 100 FMI 1 | Warning Alert |
