Volvo All Engines (2010 Emissions) Fault Code: SPN 173 FMI 15 PID: Engine Exhaust Gas Temperature – Least Severe Level

Category All Engines (2010 Emissions) Tags 15, 173, 2010, All, CodeSPN, Emissions, Engine, Engines, Exhaust, Fault, FMI, Gas, Least, Level, PID, Severe, Temperature, Volvo

This diagnostic function indicates malfunction at the exhaust gas temperature (EGT) sensor. The purpose of the exhaust gas sensor is to contribute the relevant temperatures required for the temperature regulated aftertreatment diesel particulate filter regeneration control. A faulty EGT sensor can result with a failed aftertreatment (DPF) regeneration.

Observable symptoms
1) None

Probable cause
1) Wiring harness between component connector and electronic control unit (ECU) connector
2) Exhaust Gas Temperature (EGT) Sensor
