Frequently asked questions about P23E1
What does P23E1 mean?
EGR C Control Circuit/Open. The control module detected an interruption (open circuit) in the EGR C Control circuit, so the expected electrical continuity was not present.
Is P23E1 generic or manufacturer-specific?
P23E1 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove P23E1 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.
