2000 Ford Expedition 4.6 Firing Order – It’s essential to know which bank (or cylinder head) is number 1 to help you figure out a place to start for firing order or simply to replace the appropriate component, like an Oxygen sensor, energy injector or ignition coil.
In past times all of that was required to determine which financial institution or cylinder brain is primary was to see which cylinder brain is situated the farthest forwards. One that is regarded as the forward (closest to the leading in the engine) is the main cylinder and that area is financial institution 1.
But a majority of engines right now have cylinder heads that are located uniformly, making it tougher to find out which is bank # 1 and which is banking institution second. A few typical reasons we should know this, as an illustration would be to decide Oxygen sensor to replace when you would like B1 S1 (Financial institution 1 Sensor A single), or maybe you’re seeking to locate an ignition coil to inspect for the P0301 (#1 cylinder misfire documented) misfire code.
