02 Ford 4.6 Firing Order – It’s important to know which lender (or cylinder Top) is # 1 to assist figure out a starting point for firing order or simply to change the appropriate aspect, as an Oxygen sensor, energy injector or ignition coil.
Previously all of that was needed to find out which financial institution or cylinder go is primary was to determine which cylinder go is located the farthest forwards. The one that is the most forwards (nearest to the front of the engine) is the top cylinder and therefore aspect is banking institution 1.
However, many motors these days have cylinder heads that are placed equally, that makes it tougher to find out which is banking institution # 1 and that is financial institution second. A number of popular reasons we have to know this, as an example is always to decide Oxygen sensor to switch when you are searching for B1 S1 (Financial institution 1 Indicator 1), or maybe you’re looking to identify an ignition coil to examine for any P0301 (#1 cylinder misfire captured) misfire code.
Items to try
Several cylinder engines always have the #1 cylinder nearest to the front side in the engine (only one bank).
V-6 or V-8 try to find the plug that may be nearest the front side from the engine, if the cylinder heads are even a different means of figuring out #1 will likely be needed.
Don’t overlook the apparent, check up on the spark plug cable on its own for cylinder phone numbers.
Also examine the ignition coil for phone numbers.
For those who have a check out instrument, try out disconnecting an oxygen sensing unit for the short term to determine which is B1 or B2. Normally a pending code or tough code will set quickly. Also look at the info display in the skim resource, the voltage need to typically standard to .5V.
