Frequently asked questions about P2BAB
What does P2BAB mean?
NOx Exceedence - Incorrect EGR Flow. The control module detected that the NOx Exceedence state or value did not match what was expected.
Is P2BAB generic or manufacturer-specific?
P2BAB is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
Can TuningBot remove P2BAB 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.
