2007 Ford Explorer Firing Order – It’s important to know which banking institution (or cylinder Top) is # 1 to assist determine a place to start for firing order or simply to exchange the appropriate portion, like an Oxygen indicator, gasoline injector or ignition coil.
In past times all of that was essential to find out which banking institution or cylinder head is primary was to find out which cylinder go is located the farthest forwards. The one which is the most ahead (closest to the leading of the engine) is the main cylinder and this area is banking institution 1.
However, many engines today have cylinder heads which can be located equally, that makes it more difficult to determine which is banking institution # 1 and that is financial institution # 2. A number of typical reasons we need to know this, as an illustration would be to establish Oxygen detector to switch when you are looking for B1 S1 (Banking institution 1 Indicator 1), or if perhaps you’re attempting to track down an ignition coil to examine for any P0301 (#1 cylinder misfire documented) misfire code.
