2002 Ford F150 5.4 Firing Order – It’s essential to know which banking institution (or cylinder Top) is number one to help determine a place to start for firing order or perhaps to exchange the proper component, such as an Oxygen detector, fuel injector or ignition coil.
In past times everything was needed to find out which bank or cylinder go is number 1 was to see which cylinder brain is positioned the farthest ahead. One which is regarded as the ahead (nearest to the top in the engine) is the top cylinder and therefore part is lender one.
But many engines these days have cylinder heads that are situated uniformly, making it tougher to determine which is lender # 1 and which is financial institution second. A few frequent reasons we must know this, as an illustration is usually to decide Oxygen sensor to exchange when you are looking for B1 S1 (Financial institution One particular Sensing unit A single), or maybe you’re looking to find an ignition coil to inspect for a P0301 (#1 cylinder misfire documented) misfire code.
