• A faulty spark plugs
• An open or shorted fuel injector
• Ignition coil 11 circuit poor electrical connection
• A clogged or defective fuel injector
• A faulty ignition coils
• Fuel injector 11 circuit poor electrical connection

• Insufficient pressure in the cylinder
• A leak of intake air
• Faulty spark plugs 11
• Clogged or faulty fuel injector 11
• Faulty ignition coil 11
• Fuel injector 11 harness is open or shorted
• Incorrect fuel pressure
• Ignition coil 11 harness is open or shorted
• Insufficient cylinder 11 compression
• Incorrect fuel pressure Intake air leak

1. Spark Plug - Do you remember when was the last time you got your car Spark Plug checked up? A faulty Spark Plug can cause a lot of issues like displaying P0311 code.
2. Head Gasket - Poor Head Gasket can cause a lot of difficulties, so why not get it replaced at time?
3. Camshaft Sensor - Are there some faults in your Camshaft Sensor? Don’t waste time and get them replaced or else P0311 code can turn up.
4. Powertrain Control Module - OBD Code P0311 can appear because of faulty Powertrain Control Module.
5. Crankshaft Sensor - Everything is fine with Head Gasket and still P0311 code triggering? Then you must get your Crankshaft Sensor checked.
6. Fuel Injector - There can be some issues with the Fuel Injector due to which you may see P0311 code appearing over and over again. Visit us to buy best quality Fuel Injector online.
7. Oxygen Sensor - A lot of issues can arise due to defective Oxygen Sensor. Did you just see P0311 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.

• Hesitations as well as jerking when accelerating

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0311:

There can be some cases where a misfiring cylinder can be fixed by replacing some or all of its ignition components, including:

• The spark plugs
• The fuel injector
• The ignition coils
• The ignition coil wiring

If the cause of problem is not the ignition components, then this issue can be fixed by repairing or replacing a leaking head gasket or exhaust valve.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of Coolant Temperature Sensor, Air Fuel Ratio Sensor, Oxygen Sensor and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

If an OBD-II scanner would be used to detect the P0311 code, then a mechanic will know which cylinder is misfiring and can then take steps to diagnose the problem. One of the first diagnostic steps to take is to switch ignition components between cylinder 11 and one of the good cylinders. After switching the components, the mechanic will clear the code and operate the vehicle again to see if the misfire code moves to the new cylinder. If this is the case, then one or more of the components is the problem and should be repaired or replaced.

If switching components leads to the same P0311 code, then the problem could be a compression issue. The most likely causes for this include problems with the exhaust valves or leaks in the head gasket. The mechanic will look for coolant leaks or an overheating engine as potential indicators of a head gasket problem.

Common Mistakes When Diagnosing The P0311 Code

• Generally, the people assume that the cylinder 11’s ignition components are the problem and replacing them before testing them with a good cylinder is a common problem.
• It would be best to do a thorough diagnosis and determine exactly what the problem is before jumping to any conclusions
