Check for bad connections/replace the sensor if faulty.

You need an auto electrician with a pro grade scan tool computer. It will tell you exactly the issue within 10 minutes.

Question moved to Honda Accord category.

The problem with code P1399 is that it a random misfire where the ECM can't tell from where or why. Even the mass of information on the internet can't come to a common conclusion. What you could do is join one of the Honda Forums and post there because someone there may have had the same issue. The forums are often shadowed by Honda mechanics who may have seen this before. Copy and Paste my corrected text, don't write your own again!

Have you replaced the ignition wires?

code p0300 refers to--random/multiple cylinder/s misfire detected...Causes---spark plugs---HT leads---injectors---ignition coils ---low compression ---wiring
code p0302 refers to cylinder 2 misfire detected Causes ---engine mechanical fault---wiring---ignition/fuel system ---ECT/MAF sensors ECM
code po303 refers to cylinder 3 misfire detected Causes Engine mechanical fault---wiring---ignition/ fuel system ---injector---ECT/MAF sensor ECM The common fault to all is the fuel/system ignition
I would have the injectors checked and have a pressure test done on the fuel manifold to check pump and fuel regulator valve.

On most Honda's when you get a misfire happening across the whole engine like that there are a few likely issues. the ignition coil if it's a single coil style or the connector at the distributor. They also have some issues with EGR's and plugged ports which can mess with the fuel trim numbers. It's important to check the fuel pressure and if possible a timing offset spec from the scanner whenever you're dealing with misfires on any vehicles Honda or not and determine correct pressure and flow whenever possible.


Hope this helps.

A blinking check engine light is a signal that a damaging misfire is occurring in one or more cylinders. Your car is shaking because of the uneven power loss between firing cylinders and those that are misfiring. If you take your car to a major auto parts store, they will read out the stored trouble codes in your car's computer memory--and they'll do it for free. These codes will tell you which cylinders are misfiring and will help you find out why. Do it soon before more engine damage occurs--$$$$.

Code P1399 is specific to Honda - it is an error code for "multiple variable misfires detected". P0301-P0304 are common OBDC codes for all cars, specifically "misfire in cylinder X".

You will get the P0301-P0304 codes on your OBDC reader when you plug it in (if actually errors), but will only find the P1399 if you select Honda as the manufacturer.

Just got these errors today on my CRV 2000. Now I have to figure out what is causing two of the cylinders to misfire.

This codes: po1399 Cylinder 3 misfire

try codes 41 and code 7
