2003 Honda Pilot Ignition Coil Packs

 

The 2003 Honda Pilot came with only one type of engine: a 3.5L V6 that uses 6 ignition coil on plugs. Many people call these C.O.Ps or coil packs. As these fail, your engine will run rough and get poor fuel economy. At the same time, the check engine light will turn on. Old ignition coils tend to fail within a short period of time from each other, and replacing them one by one can be frustrating. Replacing the complete set of 6 is a good idea as well, but these typically cost around $100 at the brick and mortar auto parts store. We have the full set of 6 for a price that will blow you away. We don't reduce the price of our coil packs by lowering the quality. We do it by raising the amount we order. You local store may carry 10 on hand, while we may carry several thousand coil packs, just for the Honda Pilot. This is how we are able to get our pricing so low. Our number one question is "how are your prices so low"? We don't stop here though. We want you to save money on the entire process, not just the auto parts. We offer as much valuable information about each vehicle as we can to potentially save you some frustration

 

2003 Honda Pilot All Cylinders Misfiring

 

If your '03 Pilot has been misfiring, and after scanning the ECU, you notice that every single cylinder is misfiring (All codes showing P0301 through P0306) then you are not alone. From our experience we understand that the Honda system of this era does not always identify which cylinder is misfiring. Even if there is a misfire on cylinder 4, you may get a code for all cylinders misfiring. We don't know why, but this is very common. One way to find out which ignition coil is bad is by removing the coil, and the spark plug. Push the spark plug back into the ignition coil, and make sure the ignition coil is plugged into the harness. Touch the tip of the spark plug to a GOOD GROUND and have someone else crank the engine. In order to do this properly, the spark plug MUST be grounded or you risk damaging the ignition coil (if it was a good coil) or even the ECU when the high voltage surges back. When the engine is cranking over, you will actually see the spark plug ignite. You can also use a spark tester as well to locate a misfire. The last method is very easy, but not everybody knows what to listen for. It is safe to unplug the connector from the ignition coil while the engine is running. If the engine has a constant misfire at idle, and you unplug a fully functioning ignition coil, then you will feel the engine run even more rough, or it may even stall. This method only works if there is an ignition coil that is not functioning at all.
