Ford Focus 1.6 Zetec Firing Order – It’s essential to know which financial institution (or cylinder head) is number 1 to help determine a starting point for firing order or maybe to exchange the proper part, such as an Oxygen detector, gas injector or ignition coil.
In past times all that was essential to determine which financial institution or cylinder go is number one was to determine which cylinder go is positioned the farthest forwards. One that is considered the most ahead (nearest the leading of your engine) is the best cylinder which aspect is bank 1.
But some motors right now have cylinder heads that happen to be situated equally, that makes it harder to determine which is bank # 1 and which is financial institution number 2. Several typical motives we have to know this, as an illustration would be to decide Oxygen sensor to switch when you would like B1 S1 (Financial institution A single Indicator One particular), or if perhaps you’re attempting to identify an ignition coil to examine for a P0301 (#1 cylinder misfire captured) misfire code.
Points to consider
4 cylinder engines also have the #1 cylinder nearest to the top in the engine (just one single bank).
V-6 or V-8 try to find the connect which is nearest to the front side from the engine, in case the cylinder heads are even an alternate method of identifying #1 will probably be required.
Don’t neglect the evident, check on the spark connect wire itself for cylinder numbers.
Also look into the ignition coil for figures.
In case you have a scan resource, consider disconnecting an oxygen indicator for the short term to determine which is B1 or B2. Commonly a pending code or difficult code will set rather quickly. Also check out the details screen from the skim device, the voltage must in most cases go into default to .5V.
If everything else fails read the services manual. Several on-line resources offer easy accessibility to firing order plus much more at Do it yourself pricing.
