2007 Ford 5.4 Firing Order – It’s important to know which banking institution (or cylinder Top) is number 1 to help figure out a starting point for firing order or simply to change the correct component, just like an Oxygen sensor, gasoline injector or ignition coil.
In past times all that was essential to find out which financial institution or cylinder go is number 1 was to determine what cylinder go is positioned the farthest forward. One that is the most ahead (nearest the leading of your engine) is the best cylinder and this side is financial institution a single.
But a majority of motors these days have cylinder heads which are situated equally, which makes it more challenging to determine which is financial institution # 1 and which happens to be bank second. Several popular factors we must know this, as an example would be to figure out Oxygen sensing unit to switch when you would like B1 S1 (Financial institution One Indicator One particular), or if you’re trying to find an ignition coil to inspect to get a P0301 (#1 cylinder misfire documented) misfire code.
Things to consider
A number of cylinder motors always have the #1 cylinder nearest the top in the engine (only one bank).
V-6 or V-8 search for the connect that may be closest to the leading of your engine, in the event the cylinder heads are even another way of identifying #1 will be required.
Don’t neglect the evident, check into the spark connect wire by itself for cylinder phone numbers.
Also examine the ignition coil for phone numbers.
If you have a scan tool, try disconnecting an oxygen indicator for the short term to determine which is B1 or B2. Usually a pending code or tough code sets quickly. Also check out the data screen from the scan tool, the voltage ought to in most cases default to .5V.
If all else fails look at the assistance manual. Numerous on-line sources give comfortable access to firing order and much more at Do-it-yourself costs.
