About P2BAF

P2BAF is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Land Rover vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P2BAF is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

DTC P2BAF is set by the Engine Control Module (ECM) when the NOx control monitoring system has determined that exhaust NOx emissions have exceeded legislated limits for a defined period and corrective actions have not been successful. As a result, the ECM activates the driver inducement strategy required by emissions regulations, which escalates in stages from warning messages through engine torque limitation to a restricted speed limp mode and a no restart countdown. This code is a consequence of an unresolved underlying SCR or NOx system fault rather than a fault in its own right, so it almo...
