2001 Ford 4.0 Firing Order – It’s important to know which banking institution (or cylinder head) is # 1 to help you figure out a beginning point for firing order or perhaps to replace the proper portion, as an Oxygen sensing unit, energy injector or ignition coil.
Before all of that was required to find out which lender or cylinder head is # 1 was to find out which cylinder mind is located the farthest ahead. The one which is easily the most forward (nearest the top of the engine) is the best cylinder and that aspect is financial institution a single.
But many engines nowadays have cylinder heads that happen to be positioned consistently, making it more difficult to determine which is lender # 1 and which happens to be financial institution number two. A few popular good reasons we need to know this, for example is always to figure out Oxygen indicator to change when you are searching for B1 S1 (Bank A single Sensing unit One particular), or if you’re looking to track down an ignition coil to inspect for the P0301 (#1 cylinder misfire documented) misfire code.
