02 Ford Explorer 4.6 Firing Order – It’s important to know which lender (or cylinder head) is number one to aid figure out a place to start for firing order or just to change the correct aspect, as an Oxygen sensor, energy injector or ignition coil.
In the past all that was required to determine which financial institution or cylinder go is number 1 was to see which cylinder brain is placed the farthest frontward. One that is considered the most forwards (nearest to the leading of your engine) is the best cylinder and this area is banking institution one.
But a majority of engines today have cylinder heads that happen to be situated evenly, that makes it more challenging to find out which is bank number one and which happens to be financial institution # 2. Several frequent reasons we need to know this, as an example is to figure out Oxygen sensing unit to change when you are searching for B1 S1 (Bank A single Detector One particular), or if you’re trying to track down an ignition coil to inspect for a P0301 (#1 cylinder misfire documented) misfire code.
