Want this question answered?
It means that more than one cylinder has a misfire history. PO301 would be cylinder number 1 misfire. PO302 would be number 3 cylinder misfire.
P0301 is cylinder number one misfire detected.P0301 is cylinder number one misfire detected.
what are the possible causes of misfire on number one cylinder in a dodge 2003 ram 4.7 liter engine
I found the easiest way to do this is read the codes, if it is reading a misfire on one cylinder, then swap that coil pack with one of the other cylinders coil packs, then you will have to clear the codes and drive it, then see if it throws a new code on a different cylinder.
I'm not a mechanic / technician but I BELIEVE if the fuel injector is restricted so that the proper air - fuel mixture is not getting to an engine cylinder , that an engine cylinder misfire can occur ( that is only one of the causes of an engine cylinder misfire )
A misfire is when one of the cylinders is accelerating without actually doing anything, it's just a dead-cylinder. In order to fix this you need to tighten the cylinder or adjust the engine connector.
Theres three coil packs; one fires two cylinders. I suppose if one is bad then it could cause the two corresponding to misfire. I had one cylinder misfire, it turned out to be the fuel injector.
The crankshaft and camshaft sensors monitor engine speed. When the sensors detect a change in speed, they attribute it to a misfire. Depending on the cylinder that was supposed to fire, the engine can determine when the change in speed took place and can single out a particular cylinder. When it happens with more than one cylinder, it becomes a mulit cyl misfire. This is one of the symptoms of a malfunctioning cam or crank sensor.
Need to know what year and what engine to help you.
That would be an engine cylinder misfire , but either more than one or it can't determine which engine cylinder is misfiring
If cylinder one is misfiring on the Kia Sportage 2.0 it could be that the spark plug in that cylinder needs to be changed. It can also mean that the piston in that cylinder is sticking.
Anything that could cause a cylinder misfire can cause the check engine light to flash. A restricted fuel filter is one.Anything that could cause a cylinder misfire can cause the check engine light to flash. A restricted fuel filter is one.
