CODE P1193 FOR JAGUAR 1997 XJ6L . I HAVE CODES PO300,P1313 P1314,P1193,PO158,PO138, P1157, P1138. JUST CHANGED ALL 4 O2 SENSORS AND GOT ALL THIS CODES.

You need to get your vehicle to a good mechanic as this could be almost anything! One of the cylinders isn't firing correctly. This could be a fuel, an air or a spark issue. It will need further investigation. It also suggests there might be a problem with one of the O2 sensors on the exhaust system. I was unable to find a listing for P1317.
P0306 = Cylinder 6 - misfire detected.
P1000 = OBD Systems Readiness Test Not Complete.
P1314 = Misfire Rate Catalyst Damage Fault - Bank 2.
P1316 = Misfire Rate Exceeds Emissions.
P1317 = (no code found).
P1647 = Linear O2 Sensor Control Chip (Bank 2).

p0306 is misfire with number 6 cylinder P0306 Cylinder 6 Misfire Detected and p1314 cat converter problem P1314 Misfire Rate Catalyst Damage Fault Bank 2 P1314

the engine managment system on this car treats each bank as 2 seperate engines bank 1 and bank 2 the fault codes you have got are emission related. diagnosis is not easy because the ecu will use the other bank to compensate and alter its fueling etc to reduce emissions. the only way to sort it out is to put it on suitable diagnostic equipment and monitor live data ie. lambda sensors/ catalyst efficiency hope this helps

PO204,205 are injector circuit malfunction,PO174 is a system lean code, PO175 is system rich code, PO138 is heated oxygen sensor bank1 sensor 2 circuit high voltage, PO158 is heated oxygen sensor bank2 sensor 2 circuit high voltage. This is a repair for your mechanic. When they fix the injector and o2 circuits the rich lean codes will also be repaired. Continued driving will ruin your catalytic converter. Good luck

related peoblem 02 sensors multiple misfire mis fire cyl 5

the fault codes you have are all misfire codes p1313 and p1314 are manufactuer codes only. but they all point to same issue check the engine wiring harness under the air box for chaffing also the on plug coils are very unreliable the spark plug internal resistance is critical use only genuine plugs we had to change all 6 because pattern plugs had been fitted and check for water ingress in to the ecm/connector that may be the problem

Have you tried to get any codes off the check engine light?

CODE P1313 MISFIRE CATALYST DAMAGE BANK 1 CODE P1314 MISFIRE CATALYST DAMAGE BANK 2 COULD BE MANY THINGS THAT CAUSE THAT PROBLEM.FAULTY EGR VALVE FAULTY MASS AIR FLOW SENSOR OR BAD COOLANT SENSOR BAD O2 SENSORS.LEAKING INTAKE MANIFOLD LEAKING EXHAUST PIPE OR EXHAUST MANIFOLD.

Bad O2 sensor
