2001 Ford F150 Firing Order 4.6 – It’s crucial that you know which banking institution (or cylinder Top) is # 1 to aid determine a starting place for firing order or simply to replace the right part, like an Oxygen detector, energy injector or ignition coil.
Previously everything was needed to determine which banking institution or cylinder head is primary was to determine what cylinder go is placed the farthest frontward. The one which is easily the most frontward (nearest the top of your engine) is the top cylinder and this side is bank a single.
But some engines nowadays have cylinder heads which are situated evenly, that makes it tougher to determine which is banking institution number one and which happens to be banking institution second. A couple of frequent reasons we must know this, for example is usually to determine Oxygen indicator to switch when you are searching for B1 S1 (Bank One Sensor 1), or if perhaps you’re trying to locate an ignition coil to inspect for a P0301 (#1 cylinder misfire saved) misfire code.
