Fixing the problem causing the code to fire can save you time and money and keep your Ford from breaking down.
P0300 is cause for concern and left unfixed can get worse. Replacing the spark plugs, coil packs, and plug wires is not typically difficult or costly. When it’s not glaringly obvious what is wrong, a tune up is a great place to start. You should also feel the vehicle is down on power as well.Ī lot of the time, P0300 is going to be fixed by something obvious, such as an EGR leak. that would cause compression to not be as high as it should, you’re going to get P0300.

Low Compression– If you have a leaking head gasket, bent valve, cracked head, etc.If the ECU is not getting the right signal from these sensors, the vehicles timing is not going to sync up and it’ll misfire. Cam or Crank Sensors– This one is very unlikely, but it does happen.
#FORD ENGINE CODES PO302 5.O F150 HOW TO#
Here’s how to test a coil pack, how to tell if a spark plug is bad (video), and how to test plug wires (video). If you got a P302 or something similar with the P0300, it may be a good idea to check and see if there is any damage or failure from your ignition components. This isn’t higher on the list because typically you’ll get a misfire in one cylinder specifically, and not a P0300 only. Ignition Problems– Bad plug wires (if equipped), bad coil packs, and spark plugs can cause misfires to occur.EGR Problems– If the EGR system is not able to recycle the engine gasses right, it’ll throw P0300.Popular Mechanics: How to find a vacuum leak. It’s easy (and kind of fun) to chase one down. Here’s a great article from Popular Mechanics on how to detect a vacuum leak. Also, since a vacuum leak almost always affects each cylinder the same, you’ll typically get P0300 with it and not any cylinder specific misfire codes.
This will cause the cylinders to misfire and it’ll throw the P0300. Vacuum leak– If your F150 has a vacuum leak, it can be very difficult for it to get the right air/fuel mixture.Here’s some information on how to tell if you have a bad fuel filter. But, it’ll sputter and act like it’s going to die at speed or under heavy acceleration. Typically, if you do have low fuel pressure, the vehicle will act fine when it doesn’t need a lot of fuel. Diagnosing low fuel pressure can be tricky. Low Fuel Pressure– If there isn’t enough fuel getting to the engine, this will cause combustion to be less than optimal.They are presented somewhat in order from most to least likely to be causing the code: Here are the most common problems that will throw the code. There are quite a few things that can cause the P0300 trouble code to trigger the Ford F150. The vehicle may produce excess vibration, espescially at lower RPM.It depends on how serious the misfire is. The vehicle itself may begin to run rough.The P0300 Ford trouble code will trigger the F150’s service engine soon light.Something is causing cylinders to misfire at random, which is a lot less cut and dry than a cylinder specific misfire code. P0300 is a general and random misfire code, which means that the code is not going to tell you which cylinder is causing the misfire. If you have P0300 and one of these other codes, the cylinder indicated by the cylinder specific codes would be where to start looking for your problem. These particular codes also indicate that there is a misfire detected, but they specify the specific cylinder. It will often be accompanied by codes P0301-P0308. P0300 is certainly a cause for concern, and can be a threat to the drivability the Ford F150. P0300 : Random, Multiple Misfire Detected
In Spark Ignition Direct Injection (SIDI) system applications, if a fuel injector fault DTC is set during a misfire event, the ECM will not re-enable the injector.P0300 is a very common OBDII codes that occurs in the Ford F150. If the misfire is not present, the fuel injector will remain enabled by the ECM. If the misfire is still present, the ECM will disable the fuel injector again repeating the process. The ECM will then re-enable the fuel injector and, after approximately 200 engine revolutions, will determine if the misfire is still present. When the ECM detects that one or more specific cylinders are misfiring, the DTC for the respective misfiring cylinder will set, and up to 2 of the corresponding fuel injectors are disabled for a minimum of 30 s. The Diagnostic Trouble Codes (DTC) P0302 correspond to cylinders 2. The malfunction indicator lamp (MIL) will flash when the conditions for catalytic converter damage are present. By monitoring variations in the crankshaft rotation speed for each cylinder, the ECM can detect individual cylinder misfire events.Įxtreme cylinder misfire events can cause catalytic converter damage. The Engine Control Module (ECM) uses information from the crankshaft position sensor and the camshaft position sensor to determine when an engine cylinder misfire is occurring.
