Q: What does code P1401 mean?

Exhaust Gas Recirculation Valve Postion Circuit. P1401 on a Jaguar indicates that the engine control module (ECM) has detected an electrical fault in the exhaust gas recirculation (EGR) valve position circuit, which monitors how far the valve pintle has moved. The ECM compares the expected position signal against the actual feedback voltage and sets this code when the two disagree beyond a calibrated threshold or when the signal is out of range.
