P0306 OBD II Trouble Code Cylinder 6 Misfire Detected

P0300 = Random/multiple cylinder(s) - misfire detected.
P0302 = Cylinder 2 - misfire detected.
P0304 = Cylinder 4 - misfire detected.
P0306 = Cylinder 6 - misfire detected.

A misfire can be caused by a few things. The most common causes are usually spark supply or fuel supply. Get BOTH of these checked.
All the misfires are on the same side of the engine so I would suspect a fuel rail or an injector issue on that side of the engine.

There are few possibilities that can cause engine misfire issues. It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

Thanks.

code p 0306 is misfire detected no 6 cylinder causes electrics
more likely a bad injector , injector wiring or dirty tip

Diagnostic Test Code (DTC) P0306 is defined by SAE J2012 (REV, DEC 2007) as "Cylinder 6 Misfire Detected".

To put it plain and simple, there is a problem with cylinder #6 in your engine that is causing it to misfire.

Misfires can be caused by several things. One of the things that must be understood is that a misfire is simply one or more cylinders that are not producing the power that they should. - especially when compared to other cylinders in the same engine.
The things that can cause this include, but are not limited to:
> Ignition system
> Fuel delivery system
> Fuel injection system
> Cylinder compression (which can be affected by many of the things below)
> blown head gasket
> Burned or bent valves
> Vacuum leaks
> Faulty wiring
> cracked piston or broken piston rings
> Restricted exhaust
> malfunctioning Powertrain/Engine Control Module (PCM or ECM)


To fix the code, you must first diagnose to determine which of these things is causing the misfire, then repair accordingly.

Okay, you were getting code P0306, and a P0316. You have replaced plugs and swapped coils around are you still getting the code P0306? or is it a different code for a different cylinder now? Replacing your crankshaft position sensor in this case will merely waste your money. Its doing its job, the P0316 is telling you you had a misfire in the first 1000 revolutions of your engine at startup, the P0306 is telling you its probably cylinder #6 that had the problem. there is no code there indicating your CKP is bad.

Now if you swapped your coils and the misfire is still on cylinder 6, its either injector problem, or base engine. If the misfire has moved to another cylinder, replace that COP.

Hope helps.

P0305 - Cylinder 5 Misfire Detected
P0306 - Cylinder 6 Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, The Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

When is the code detected?
- Engine Cylinder #5 and #6 is Misfiring.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation

Possible Causes:
- Improper spark plug at cylinder #5 and #6
- Insufficient compression at cylinder #5 and #6
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #5 and #6
- Fuel injector #5 and #6 may be faulty
- Intake air leak at cyli

Possible Solution:
- Perform Injector Service
- Replaced Spark Plug #5 and #6
- Replaced Injector #5 and #6
- Replaced Ignition Coil #5 and #6

Hope helps.
