The code P0302, Missfiring detacted at cylinder # 2.
The Code P1313, Catalystic Damaged Bank A , due to Missfiring.
The code P1000, Transsmission check Not completed. during test.

OK. The Important of this problem is, Check the Engine compression on the Cylinder 2.
If the compression is GOOD, Maybe you cen solve the problem Making a TUNE-UP.
But if the compression is LOW, You will need to spend Mony to REBUILT THE ENGINE or HEADS.

OK.. The catalystic come Damaged due to the Missfiring, And will need to replace.

The code P1000. You need a transmission compatible scanner to see if there a code on the Trans.

OK... I hope this help on your question

Thank you for use fixya.....

    Hi... The code P1000 ..

    You need a Scanner Compatible with Transmission. to get Codes if there.

    The code P1000. just mean the Scanner is not Able to get Trans, codes.

    But maybe are not Trans, codes..

    OK. To replace the CATALYSTIC depend on the Muffler shop..

    And Really I have no IDEA..

    OK.. Thank you, I hope this help to you.

2002 faguar s type 2.5l P0301 P1313 P0420 P0430 P1000 ,what is the problem and how do i fix it?

0301 Indicates a misfire on cyl no.1
1313 Indicates Misfire
0420 & 0430 Indicate bad reading from cat

My thoughts would be to change No. 1 plug and coil. This should cure your problem and p1000will then clear automatically

2003 Jaguar X Type has p1314,p0300,p1313,,p0303,p0301,p0302,p0305

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

What does the service code p1111 mean?

Copied directly from a Jaguar forum:

P1111 is not a fault code. It is a special designator Jaguar uses meaning system ready, drive cycles completed after the last fault event. P1000, on the other hand, means system not ready, or drive cycles not completed after the last recorded fault event.

Some OBD II Basics - All P0xxx codes are generic and uniform across all manufacturers and mean the same on every car. All P1xxx codes are manufacturer specific codes. You cannot use a generic code chart to analyze P1xxx codes for a Jaguar.

Next time your car displays an engine fault light, try reading the codes then. If you have a CEL illuminated and the only code read is P1000 or P1111, then you probably have a fault that generic code readers cannot see. Could be a chassis code, for example.

One last thing - Neither P1000, nor P1111 can be erased.

Hope this helps you.

My x type upon wide open throttle or passing starts to shudder losses power unil i slow down codes misfire and 1313 and 1000 410 420

P1313 Misfire Rate Catalyst Damage Fault - Bank 1

P1000 BD System Check Not Complete Since Last Memory Clear

P0410 Secondary Air Injection System

P0420 Catalytic Converter System Efficiency Below Threshold - Bank 1

I'm gonna go out on a limb here and say your catalytic convertor is damaged. Do not drive this car. A damaged convertor can ruin your engine or catch on fire.

P1193 is the heated O2 sensor, P0300 is a random missfire, P1313 P1314 are Catalist damage banks A and B, the rest of the 'P' codes are all to do with the same area, have you changed one at a time? or both at once? as the conectors can be crossed and this will throw the ECU out, generating the fault codes given.
You will need a Jag garage to re set the sensors.
