Volvo All Engines (2017 Emissions) Fault Code: P04DA00 PID: EMS Closed Loop EGR Control At Limit – Flow Too High

This function is used to calculate the EGR Mass Flow. The Engine Control Module (ECM) monitors the EGR diffpressure sensor and the EGR temperature sensor after cooler and uses these signals to calculate the EGR Mass Flow data.

Conditions for diagnostic trouble code (DTC):
1) EGR mass flow above calculated value
2) The EGR mass flow is an calculated value based on a number of sensor signals and software calculations

Probable cause
1) Connector
2) Wiring harness
3) EGR Valve
4) EGR differential pressure sensor

Detailed information
1) The diagnostic trouble code (DTC) will be shown as inactive when the ignition key is turned to the 0 position
2) To fully verify the repair it may be necessary to activate vehicle functions or perform a test drive
