Volvo All Engines (2017 Emissions) Fault Code: P111186 PID: EMS Exhausy Gas Temperature Sensor Bank 1 Sensor 1 Electrical
Volvo All Engines (2017 Emissions) Fault Code: P111186 PID: EMS Exhausy Gas Temperature Sensor Bank 1 Sensor 1 Electrical
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 signal is stuck
2) Sensor value does not change with changing conditions
Observable symptoms
1) Regeneration not possible
Probable cause
1) Aftertreatment exhaust gas temperature (EGT) sensors installed in the incorrect location on the aftertreatment diesel particulate filter (DPF)
2) Pre-catalyst, Exhaust Gas Temperature (EGT) Sensor
