6.2 Ford Firing Order – It’s essential to know which bank (or cylinder Top) is # 1 to help you figure out a starting point for firing order or perhaps to exchange the proper aspect, just like an Oxygen sensing unit, gas injector or ignition coil.
Previously all of that was necessary to determine which lender or cylinder head is number 1 was to determine what cylinder brain is placed the farthest ahead. The one that is regarded as the forwards (closest to the leading from the engine) is the top cylinder and this aspect is financial institution one particular.
But many engines nowadays have cylinder heads that are positioned evenly, making it more challenging to determine which is bank # 1 and that is financial institution number two. A number of common motives we should know this, for example is usually to determine Oxygen indicator to exchange when you are interested in B1 S1 (Financial institution 1 Detector 1), or maybe if you’re trying to identify an ignition coil to inspect for a P0301 (#1 cylinder misfire documented) misfire code.
Things to try
A number of cylinder engines also have the #1 cylinder closest to the leading of the engine (merely one financial institution).
V-6 or V-8 seek out the connect that may be closest to the leading of your engine, when the cylinder heads are even another method of figuring out #1 is going to be required.
Don’t disregard the evident, check into the spark plug wire on its own for cylinder figures.
Also check the ignition coil for numbers.
For those who have a check out tool, consider disconnecting an oxygen sensing unit temporarily to find out which is B1 or B2. Usually a pending code or hard code will set quickly. Also look at the information display screen from the scan resource, the voltage must typically go into default to .5V.
If everything else breaks down read the service guidebook. Numerous on-line resources give easy access to firing order and a lot more at Do it yourself rates.
