Asked by Oct 21, 2019 at 11:35 AM about the Jaguar X-TYPE

Question type: Maintenance & Repair

could you please tell me what engine codes P0304, P1314, P0420 and P1111   

1 Answer

87,495

P1111 indicates that the car's diagnostic evaluation has completed. Other codes refer to a misfire in cylinder #4 and that it's damaging the O2 sensor & the catalytic converter. See a Jaguar mechanic immediately. You might lose the converter and then cause severe engine problems.
