2009 Ford Flex Firing Order – It’s important to know which bank (or cylinder head) is primary to aid decide a starting place for firing order or maybe to switch the proper portion, like an Oxygen sensor, gasoline injector or ignition coil.
Previously everything that was required to find out which bank or cylinder go is number one was to see which cylinder brain is positioned the farthest frontward. One which is regarded as the frontward (closest to the front from the engine) is the best cylinder and this side is financial institution 1.
But many engines today have cylinder heads which can be located consistently, rendering it more challenging to find out which is banking institution number 1 and that is banking institution number 2. A few popular good reasons we should know this, for instance is usually to decide Oxygen indicator to exchange when you are interested in B1 S1 (Financial institution One particular Detector One particular), or maybe if you’re looking to identify an ignition coil to inspect for any P0301 (#1 cylinder misfire documented) misfire code.
