On Honda vehicles the OBD code p1399 indicates that there is a random misfire occurring in the engine. In most cases a valve adjustment will correct this issue, however a blocked passage in the EGR (Exhaust Gas Recirculation) system can… All these codes point to engine misfires.
Starting with the most common form of misfire, ignition misfires occur when the air and fuel mixture inside your engine’s combustion chamber isn’t ignited correctly. The 2 chief parts responsible for the ignition of the fuel, the ignition coils and the spark plugs, work very hard each time you drive.
When a P0300 trouble code is triggered, it indicates that misfiring occurs in random or multiple cylinders. This happens when there is a deficient amount of fuel being burned within a cylinder. Most cars have between four and six cylinders, with each cylinder firing a spark plug continuously and smoothly.
What the P0304 code means. The P0304 code will be seen in cars where the ECU has detected that cylinder 4 is not firing properly. The ECU monitors the operation of all cylinders to ensure they are all firing on time, so when one misfires repeatedly, a Check Engine Light is set.
Cylinder 4 misfires can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure. The most common reason for this to happen is faulty or worn-out spark plug coil packs, especially if it’s been a while since you had a tune-up.
If you’ve ever had a misfire in your car, the P1399 Honda OBDII code may be a sign of trouble. This error code means that the cylinder in question has misfired, and the onboard computer will report the problem. Fortunately, repairing this code is relatively easy. To begin, you should first check the spark plug wires, which may be a sign of a faulty fuel injector.
If you don’t know how to check your car for misfires, you can purchase an OBD2 scanner. These diagnostic tools can retrieve misfiring codes, including P1399. The most common fix for a P1399 is valve adjustment, but there are other ways to fix the problem. In most cases, the code will indicate the need to replace an ignition component or adjust valve lash. P1399 can occur due to a variety of problems, including misfiring of more than one cylinder.
Another common problem is a clogged or blocked EGR passage. Cleaning out the EGR system will prevent the code from appearing, and cleaning it can be an easy fix. The most common fix for a P1399 error is to adjust the valve lash. However, before you tackle this repair, you should check other problems with your vehicle. You should first check the symptoms of the error and then determine what needs to be done.
If you’ve already changed the plugs, you might want to pull the old ones. You can try removing them one at a time to eliminate the misfiring issue. If you’re a bit braver, you can pull them all out at once. One of the people in the video pulled all three. But that’s not a cure-all solution. Make sure to take the time to test your engine.
