2002 Ford 5.4 Firing Order – It’s essential to know which bank (or cylinder Top) is primary to aid determine a starting point for firing order or simply to switch the right part, as an Oxygen indicator, gasoline injector or ignition coil.
Previously all that was required to find out which bank or cylinder mind is number 1 was to determine what cylinder head is situated the farthest forwards. The one which is considered the most forwards (closest to the leading from the engine) is the main cylinder and this part is banking institution one particular.
But some motors nowadays have cylinder heads which are positioned uniformly, that makes it more difficult to determine which is bank # 1 and which is lender number 2. A few popular good reasons we need to know this, for instance is usually to figure out Oxygen indicator to exchange when you would like B1 S1 (Lender One particular Sensor A single), or if perhaps you’re seeking to locate an ignition coil to examine for the P0301 (#1 cylinder misfire recorded) misfire code.
Points to attempt
Four cylinder engines always have the #1 cylinder closest to the front side in the engine (only one financial institution).
V-6 or V-8 seek out the connect that is certainly nearest the leading of your engine, if the cylinder heads are even a different strategy for determining #1 will probably be required.
Don’t neglect the clear, check up on the spark connect wire by itself for cylinder amounts.
Also examine the ignition coil for figures.
If you have a check out instrument, try out disconnecting an oxygen indicator temporarily to find out which is B1 or B2. Often a pending code or hard code will set rather quickly. Also consider the details screen in the skim resource, the voltage must generally default to .5V.
If all else falters browse the service handbook. Several on-line resources supply easy accessibility to firing order and even more at Do-it-yourself prices.
