Volvo All Engines (2017 Emissions) Fault Code: P242800 PID: EMS Exhaust Gas Temperature Too High
Volvo All Engines (2017 Emissions) Fault Code: P242800 PID: EMS Exhaust Gas Temperature Too High
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) High exhaust temperature, pre-catalyst
Observable symptoms
1) Low Power
Probable cause
1) Resistance too high, Wiring harness
2) Restricted catalyst
3) Charge air system leakage
4) Exhaust Gas Temperature (EGT) Sensor
Detailed information
1) Engine derate according to error torque map
2) Basic checks
