2001 Ford F150 4.6 Firing Order – It’s vital that you know which financial institution (or cylinder head) is # 1 to assist figure out a place to start for firing order or simply to exchange the correct aspect, as an Oxygen sensing unit, fuel injector or ignition coil.
In past times all that was required to determine which bank or cylinder head is primary was to determine what cylinder head is situated the farthest forward. One that is easily the most forward (nearest the top in the engine) is the best cylinder and that aspect is bank one particular.
But some motors right now have cylinder heads which can be situated evenly, that makes it more difficult to find out which is financial institution number 1 and which is bank number 2. A number of frequent good reasons we must know this, as an example is to determine Oxygen sensor to exchange when you are looking for B1 S1 (Financial institution 1 Sensor One), or maybe if you’re trying to track down an ignition coil to inspect for any P0301 (#1 cylinder misfire saved) misfire code.
