What P04E6 means
P04E6
EGR Temperature Sensor D Circuit Range/Performance
Generic · emissions
Data confidence65%
The control module judged the EGR Temperature Sensor D signal implausible: it stayed inside electrical limits but did not match the value expected for the current operating conditions.
Symptoms
MIL illuminated
Possible reduced engine performance
Possible rough idle or hesitation
Possible causes
Carbon-blocked EGR passages
Sticking or slow EGR valve
EGR actuator or position sensor fault
Wiring or connector fault
Vacuum supply fault (vacuum-operated systems)
Recommended checks
Read freeze frame data and full module scan
Check battery voltage and sensor supply
Inspect EGR wiring and connectors
Compare commanded vs actual EGR position/flow with live data
Inspect EGR valve and passages for carbon build-up
Powertrain: engine, transmission and driveline systems.

Frequently asked questions about P04E6
What does P04E6 mean?
EGR Temperature Sensor D Circuit Range/Performance. The control module judged the EGR Temperature Sensor D signal implausible: it stayed inside electrical limits but did not match the value expected for the current operating conditions.
Is P04E6 generic or manufacturer-specific?
P04E6 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove P04E6 at file level?
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
