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. Conditions for diagnostic trouble code (DTC):1) Exhaust Gas Temperature (EGT) Sensor Observable symptoms1) Low Power2) Regeneration not possible Probable cause1) Resistance too high, Wiring harness2) Discharge recirculation valve open3) Restricted catalyst4) Charge air system leakage5) Exhaust Gas Temperature (EGT) Sensor Engine derate according to error torque map1) 541??C (1006??F) – 551??C (1022??F)...

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. Conditions for diagnostic trouble code (DTC):1) The sensor value is not within an expected range2) Too high of temperature difference compared to the other DPF temperature sensors Observable symptoms1) Regeneration not possible Probable cause1) Charge air system leakage2) Exhaust system leakage3) Aftertreatment exhaust gas temperature (EGT) sensors installed in the incorrect location...

The function identifies the exhaust temperature and indicates malfunction in the exhaust system. The evaluation is done at engine load after an engine cold start via three different temperature sensors. The exhaust gas temperature is used to determine when regeneration will run. Conditions for diagnostic trouble code (DTC):1) Open circuit2) Short circuit to battery voltage3) Replace with phrase describing observable symptom or hide Probable cause1) Exhaust Gas Temperature (EGT) Sensor2) Wiring harness3) Connector4) Dosage electronic control unit (ECU) (ACM) Volvo All Engines (2010 Emissions) Fault Code: SPN 173 FMI 2 PID: Engine Exhaust Gas Temperature Volvo All Engines (2010 Emissions)...

The Engine Control Module (ECM) monitors the voltage drop across the sensor and uses this signal to warn the driver and derate the engine to avoid engine damage if the signal is not within programmed limits. Conditions for diagnostic trouble code (DTC):1) The voltage at pin A14.EB:32 is above normal value Observable symptoms1) None Probable cause1) Engine control module (ECM)2) Short circuit to 5V, Signal wire3) Short circuit to voltage supply, signal wire Volvo All Engines (2010 Emissions) Fault Code: SPN 173 FMI 5 PID: Engine Exhaust Gas Temperature Volvo All Engines (2010 Emissions) Fault Code: SPN 173 FMI 4...
