P1313 EMS
EOBD
Misfire rate catalyst damage –
bank 1 causes,
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 p1314 is the same. good luck!!

How do I fix P0300,P0301,P0303, P0305,P1313,P1316& P1646?2 weeks ago,codes were minus P1313&P1316 with P0057 added in.replaced bank2 downstream sensor,P0057 gone but 2 new codes popped up????


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

I have a Saab with a service code P0304 I looked into it usually bad ignition coil...I replaced the coil but No go, any ideas?


P0304 code means - Cylinder 4 Misfire detected.

Possible causes are:

- Faulty spark plug 4
- Clogged or faulty fuel injector 4
- Faulty ignition coil 4
- Fuel injector 4 harness is open or shorted
- Fuel injector 4 circuit poor electrical connection
- Ignition coil 4 harness is open or shorted
- Ignition coil 4 circuit poor electrical connection
- Insufficient cylinder 4 compression
- Incorrect fuel pressure
- Intake air leak

Audia4t quattro-dies at stop signs and hard starting


Your first mistake is thinking that the only thing that can cause a misfire is a coil or spark plug. Misfires can be caused by MANY things, including faulty fuel injectors, injector control circuits, blown head gaskets, vacuum leaks, burned valves, broken valve springs, low compression due to cylinder damage, worn piston rings, damaged or worn camshafts, etc..

I would recommend getting this problem properly diagnosed by a professional. Failure to fix misfire codes promptly can cause severe engine damage and destroy high-dollar parts like oxygen Sensors, catalytic converters, engine blocks and cylinder heads.

I have a 2002 Jaguar X-type. The check engine light came on and it has been acting jumpy/shaky. I recently took it to be diagnosed and the codes I recieved back were P1314, P1316, P1111, and P0302..What do...


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

Code p1313 p1316 p1111 p0301 means what?


Odd one this to have P1111 as well.

According to my data P1111 is all dtc checks compleated, http://www.bluejag.co.uk however some websites show it as a Intake Air Temperature (IAT) Sensor Circuit Intermittent High Voltage, I'm fairly sure that the latter is incorrect.

check the basics first plugs, leads, corroded ground connections etc then its a bit of a guessing game


As for the other codes

P0301 = Misfire detected - cylinder 1
P1313 = Misfire rate catalyst damage - bank 1
P1316 = Misfire excess emission


Possible causes (as per JTIS):

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

hope this helps

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.


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.
