I am getting dtc codes p0305 p1316 p1000

we can't tell you what you can do, lacking skills and tools and spares.
I can tell you what a shop does. sure.
P0300 means all cylinders of the engine are missing,
means (physics) weak combusting on all cycl.
bad spark all or bad injections to all (lean) or engine cam out of time?
P1 codes are factory only codes. Jag codes
P1000 means car is not ready for smog tests, the , onboard readiness is not complete, means drive for a day or 2 and is caused by scan tool DTC reset or battery on car went dead or was disconnected.
next P1316 _
Misfire Excess Emission, get the shop to find it.
there are a battery of test to do.
even low fuel pressure can trip p0300.
goes lean ,combustion goes weak and BINGO gross misfire.
or bad spare, but how can all fail and not get one cmp or ckp errors>?
bad fuel> too. put diesel in the gas?
park parked over 1 year or parked less, with 1/8 tank for long long months?
we can not guess history of any car.

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).

P0305 is cylinder 5 misfire unfortunate it is one under intake in rear probbible plug on coil but when intake is off replace all plugs and 3coils in rear jaguar coils only aftermarket are not the trouble

All fault codes can be checked out at http://www.bluejag.co.uk but here are the results for some of yours. You can ignor P1111. Looks like a faulty plug or coil pack cylinder 2

Fault Code:- P1314 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire rate catalyst damage -bank 2 NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- ECM Default:- Maximum engine speed reduced


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.

Possible Fault:- Cylinder compression low Worn camshaft / broken valve spring(s) Fuel delivery pressure (low / high) Fuel injector(s) restricted / leaking Fuel injector(s) continuously open Fuel contamination Fuel injector circuit fault(s) (Injector DTCs also flagged) Spark plug failure / fouled / incorrect gap ECM to ignition coil primary circuit fault (Cylinder misfire detected DTC also flagged) Ignition coil failure
Fault Code:- P1316 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire excess emission NOTE: This DTC will flag only when accompanied by an individual cylinder misfire DTC: P0300 - P0306

Action of ECM:- none


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.

Possible Fault:- Cylinder compression low Worn camshaft / broken valve spring(s) Fuel delivery pressure (low / high) Fuel injector(s) restricted / leaking Fuel injector(s) continuously open Fuel contamination Fuel injector circuit fault(s) (Injector DTCs also flagged) Spark plug failure / fouled / incorrect gap ECM to ignition coil primary circuit fault (Cylinder misfire detected DTC also flagged) Ignition coil failure

Fault Code:-
P0302 Indicates a Power-train fault


The fault is generally due to a problem in the Ignition or Misfire area


Fault Description: Misfire detected ?€" cylinder 2

Action of ECM:- none


After clearing the DTC, complete the Misfire monitor drive cycle
Check for a reoccurrence of fault DTC.

Possible Fault:- Refer to P0300 Possible Causes

Go to http://www.bluejag.co.uk/diagnosticcodes.php to get a good description of the problems. Looks like a fault on cylinder 5 to me Ignoring P1111 which dosn't matter at the moment, could be ignition coil, plug, injector etc unless there is anything else obvious in that area. (when were your plugs last changed?)

DTC P0037; RIGHT-HAND CATALYST MONITOR SENSOR HEATER CONTROL CIRCUIT LOW/HIGH RESISTANCE
DTC P0300; RANDOM MISFIRE DETECTED, MISFIRE DETECTED, PRIMARY CIRCUIT MALFUNCTION
DTC P0305; RANDOM MISFIRE DETECTED, MISFIRE DETECTED,
P1316 IS A MISFIRED OF A CATALYST FOR EX.SPARK PLUG,INJECTOR PRESSURE ,IN GENERAL ITS THE MISFIRED DRIVE CYCLE ...SOMETHING IS FIRING PROPERLY..LET ME ASK HOW MANY MILES DO YOU HAVE.?AND CODE P1111 IS NOTHING TO BE WORRIED ABOUT ITS THE SYSTEM READINESS TEST THAT THE CARS ECM PERFORMS WHEN YOU CUT IT OFF EACH TIME...MAKES SURE THAT ALL IS FUNCTING WELL.

P1000 JAGUAR - On Board Diagnostic System Readiness Test Not Complete, this is known as the OBD2 drive cycle.


Possible causes - The vehicle is new from the factory.
- Battery or Powertrain Control Module (PCM) had recently been disconnected.
- An OBD monitor failure occurred before completion of an OBD drive cycle.
- PCM Detected Trouble Codes (DTC) have recently been cleared with a scan tool.
When is the code detected? If DTC P1000 is triggered after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles have not been cleared. P1000 JAGUAR Description The On Board Diagnostic (OBD) monitors are performed during the OBD Drive Cycle. P1000 is stored in continuous memory if any of the OBD monitors do not carry out their full diagnostic check.

THE P0302 is misfire cyclinder 2,4,and 5
The P1313 P1316 is Cyclinder compressor low, Worn camshaft/ broken valve springs. Fuel injector contamination, Spark plug failure/ incorrect gap. Iginition coil failure.
P0778 is 2/4 Brake prssure solenoid failure

HOPE THIS CAN HELP.

P1645 EVAP Solenoid Output Circuit
P1000 Scan not complete. meaning it didnt finish scanning
