Diagnose and resolve common Caterpillar sensor failures to reduce downtime by up to 45%. Our guide provides compliance teams with templates and KPIs to ensure rapid repairs and regulatory adherence.
Achieve 90% resolution accuracy for sensor-related faults.
Sensor failures in Caterpillar equipment, such as coolant temperature or pressure sensors, trigger DTCs that impact performance. This guide, linked with top 50 codes and fixes, helps compliance teams address issues swiftly.
Effective diagnosis ensures regulatory compliance and minimizes operational disruptions.
| Sensor Type | Common DTC | Impact |
|---|---|---|
| Coolant Temp | SPN 110 FMI 15 | Derate/Shutdown |
| Intake Pressure | SPN 102 FMI 2 | Performance Loss |
| Oil Pressure | SPN 100 FMI 4 | Warning Alert |
| Exhaust Gas | SPN 173 FMI 3 | Emissions Issue |

Expert insights for managing sensor issues
Coolant temperature (SPN 110), intake pressure (SPN 102), oil pressure (SPN 100), and exhaust gas sensors are most frequent.
Read DTCs with Cat ET or HVI, test sensor voltage, and inspect wiring for damage or loose connections.
Critical sensor failures, like emissions-related DTCs, must be logged and repaired per FMCSA rules to avoid violations.
Regular maintenance, using dataloggers, and monitoring trends can reduce failures by 30%.
Track sensor failure frequency, resolution time, compliance score, and downtime reduction using HVI’s analytics.
