Start with this thread
https://www.jaguarforums.com/forum/s...ad.php?t=46914
and look up the codes where it says, then read the possible causes.
Also, use this forum's Search for each code and see what others found.
With so many of those types, you almost certainly have an air leak. Search about that.
It will likely be the PCV hose elbow but read up and you'll see that's not the only possibility.

Yep, check for threads discussing the codes, and check the age and state of your battery's charge. A battery can start the engine with one or two weak cells whilst leaving a Jag's multitudes of electronics without enough amps and volts...resulting in a plethora of codes and warning lights.

I have a 2003 Jaguar S Type 3.0. The car stop jumping and then a check engine light came on. I just took it to Advance Auto Parts and it had 8 codes. Could anyone tell me what I need done for these codes?
P0300
P0301
P0305
P0306
P1316
P0420
P0460
P1111
Thanks in advance.

Thanks in advance.
PO301 = Cylinder 1 misfire detected
PO305 = Cylinder 5 misfire detected
PO306 = Cylinder 6 misfire detected
P1316 = IDM code detected
PO420 = Catalyst System Efficiency below threshold
PO460 = Fuel level sensor circuit malfunction
P1111 = IAT Sensor circuit intermittent voltage high
your welcome..

You must (that's MUST) look them up as Jeff and I said in that thread I gave.
That way you get the right meaning.
You also get a list of jag's best knowledge of the possible causes.
(Wherever you looked them up - I'd never use it again.)

P0301 through P0306 - correct above
P0420 - Catalytic converter system
efficiency below threshold –
bank 1P0460 - correct above
P1111 - System (OBD) checks complete
since last memory clear
P1316 - Misfire excess emission
NOTE: This DTC will flag only
when accompanied by an
individual cylinder misfire DTC:
P0300 – P0308when accompanied by an
individual cylinder misfire DTC:
For the OP (romoan22)..... What exactly is "stop jumping". Please further explain any drivability issues. Also, when the light came on, was it Amber or Red? Was there any message displayed like "restricted performance", "gearbox fault", etc.? Does the light stay on, or only light while the car is "behaving badly"?
Await your reply.

You need to stay with one problem but give us all the details related to it. This will help to define the codes http://www.gusglikas.com/images/Auto..._OBD_II_R2.pdf Looking at your codes it would not be uncommon to suggest a problem with the fuel presentation to the cylinders it could be fuel injectors or contaminated fuel and that is a guess. The P0420 suggests a problem with your Catalytic converter, H02 sensor failure or a loose connection. P0460 is fuel level sensor I think is another problem. The P1316 is related to the cylinders.
You say that the light goes out after it worms up, is this when you are driving or at idle? Did this all take place at once? When this all began did you do anything like fill the tank, work under the hood or change a part prior to this?
Not sure if you have access to do any searching or use the other applications until your probationary period is up unless you received an early access.

Hi Gus.
I have this issue this morning on my 2003 S-type 3.0.
The engine felt it's skipping some beats when I tried to accelerate. While the check engine lights was blinking and decreases performace on the display. Finally stablizes around 50mph. But the engine feels unhappy.
Going back earlier this morning. I didn't drive the car for a day(yesterday). I decided to put the left over Engine additive that I used the night before on my ML430. It's a RisloneŽ Compression Repair with Ring SealŽ Restores Lost Engine Power. Was a bit frozen and very sticky. I added about 1/4 content. Then started the cold engine. Sounded ok. Drove for about 1/2 mile then stopped to pay the toll. That when the vibration came up on the engine. I was so scared.. I made it work at steady 55mph.
2 things I first thought the cause of the problem. 1. bad additive combination (too thick). 2. Too much oil in the crankcase.
I decided to flush all the oil out (only 2mths old) and replace with new.
And put a fuel system cleaner thought maybe excess oil fouled the plugs.
I checked the codes and came up with
P305 Cylinder 5 misfire detected
P1313
P1316
Which I think all of these are caused by the misfire.
Would me adding that additive be the culprit? or just a coincedense with a new issue - bad coil pack. I just got Valve head gasket, o-ring intake gasket, spark plugs (Iridium) all replaced + oil change about 2mths ago.
I got this work done because there was and I think still is a sipping oil at the farthest left corner of the engine -if you're standing outside in front of the car.
Someone says the Iridiums are not the best plug replacement. NGK is oem or BOSCH 2+ is better.
Please please advice.

Blinking light means catalyst damaging misfires - the serious kind.
I wouldn't mess with additives etc at all but especially not till you fix the misfires. Could be expensive to wait.
Plugs? Use the recommended ones. People may say otherwise but when chasing misfires don't mess and make things worse. You'll never fix them!
Coils give problems quite often and are a wear item due to the heat etc.

There is a fault with the gearbox that the computer is telling you about. Generally brought on due to your misfiring engine problems.
Have you corrected the misfire problems yet? I would start there then worry about the gearbox (transmission) fault, again most likely to go away when the engine is repaired.
How many miles are on your vehicle?

Did you replace the IMT O-rings as well?

If there are signs of oil on the paper towel then look here: https://www.jaguarforums.com/forum/s...ad.php?t=32135
Just noticed that pogeeco posted back in Dec., with no resolution (sorry)
