02 Ford Explorer 4.0 Firing Order – It’s vital that you know which lender (or cylinder Top) is number one to aid establish a place to start for firing order or perhaps to exchange the appropriate portion, as an Oxygen sensing unit, fuel injector or ignition coil.
In past times all that was needed to determine which financial institution or cylinder go is # 1 was to see which cylinder go is located the farthest ahead. The one which is considered the most forwards (closest to the top from the engine) is the number one cylinder and this aspect is financial institution one particular.
But many motors right now have cylinder heads that happen to be positioned equally, making it more difficult to determine which is lender # 1 and that is financial institution number 2. A couple of common motives we need to know this, for instance is to determine Oxygen sensor to change when you would like B1 S1 (Lender One particular Detector One), or if you’re trying to track down an ignition coil to inspect for any P0301 (#1 cylinder misfire saved) misfire code.
