What P04CE means

P04CE
EGR Temperature Sensor C Circuit Generic · emissions Data confidence 65%

The control module detected improper operation of the EGR Temperature Sensor C circuit.

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
  • Check related vacuum lines where fitted

Frequently asked questions about P04CE

What does P04CE mean?

EGR Temperature Sensor C Circuit. The control module detected improper operation of the EGR Temperature Sensor C circuit.

Is P04CE generic or manufacturer-specific?

P04CE is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove P04CE 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.
