These particular codes indicate that there is a misfire in one of the other cylinders as well.įixing P0302 should be a high priority. It will often be accompanied by codes P0301-P0308. The nice thing about it is that the P0302 has tracked the problem to a particular cylinder, which makes diagnosing the problems simpler than P0300, which means that the cylinders are randomly misfiring. P0302 is certainly a cause for concern, and can be a threat to the drivability the Ford F150. Quick action may also save your catalytic converter from going bad.P0302 is a relatively common Ford F150 trouble code.

Fixing the problem causing the code to fire can save you time and money and keep your Ford F150 from breaking down. P0302 is cause for concern and left unfixed can leave you stranded or make the vehicle virtually underivable. If that doesn’t work, it may be time to do a compression test and see if you have a leak in that cylinder.

There are links above that’ll show you how to do that. It’s an easy, and cheap method of determining if your ignition components have gone bad.Īfter that you would want to test the fuel injection system. Go ahead and replace them or have them tested. If you get a different P030X code, you’ll know that one of those three components is bad. You can always reset the trouble codes and swap the coil pack, wire, and plug from Cylinder 2 to another. Inspect and test the parts of the ignition system around Cylinder 2 to determine whether or not you need to replace the coil packs, plugs, or wires. If you follow the items listed above you should be able to fix the P0302. You should also feel the vehicle is down on power as well. that would cause compression to not be as high as it should, you’re going to get P0302.

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.Popular Mechanics: How to find a vacuum leak. It’s easy (and kind of fun) to chase one down. This will cause the cylinders to misfire and it’ll throw the P0302 if the leak is around that specific cylinder on the intake manifold. Vacuum leak– If your F150 has a vacuum leak, it can be very difficult for it to get the right air/fuel mixture.This is definitely not the place to start. Here’s a good video on how to diagnose an injector, but it can be a little tricky. Bad Fuel Injector– If you have a fuel injector that has gone bad, it won’t be able to properly atomize the fuel and you’ll get the P0302.Coil Packs– Coil packs rarely go bad, but when they do, they can certainly cause P0302 in your Ford F150.Here’s how to tell if your plug wires are bad (video). Spark Plug Wires– On most modern engines, the plug wires are not nearly as long as they once were, but they can still go bad.

Here’s a great video on how to see if a spark plug is bad. That being said, the plugs are a great place to start. Most vehicles now come with iridium plugs that need changed very infrequently. Take a look at the electrodes and see if they are in good shape. Bad Spark Plugs– Spark plugs are one of the most common causes of P0302.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 P0302 trouble code to trigger the Ford F150. You may smell raw gas coming from the tail pipe.The vehicle may produce excess vibration, especially at lower RPM.It depends on how serious the misfire is.

The vehicle itself may begin to run rough.The P0302 trouble code will trigger the F150’s service engine soon light.An important thing to understand when finding the location of cylinder one is that it’s going to be the first cylinder in the firing order of the vehicle, and not the first cylinder that you might see when looking at the engine.

P0302 is a cylinder specific misfire code, which means that cylinder 2 is misfiring and causing the code. Mileage may suffer as well when your F150 has P0302. Raw fuel is also passing through the cylinder into the exhaust. Driving with a misfire can damage that catalytic converter. Unlike a lot of the OBDII codes, this code has to do directly with engine combustion. P0302 is a relatively common Ford F150 trouble code.
