I just change the Ignition coil from position and if the Engine code change that mean the ignition coil is bad. For example a Corolla with a P0301 (misfire in cylinder 1) Switch the ignition coil #1 to cylinder #4 and #4 to 1 and if a new Error Code come out now is P0304 that mean the IG Coil is bad if still giving you only the same Engine code P0301 that mean you could have Spark, Fuel injection or compression Fail on that cylinder so the diagnostic is more advanced which mean the costumer have to paid more. Since changing a Ignition coil test only take like 1min to test VS a Full diagnostic but you can make the same test swapping the Spark and also the Fuel injection to another cylinder and check out if the error code change or still the same.
this is not the purpose of this test, any body knows switching coils from one cylinder to another is a good way to see if the mis moves, also if there an easy is access but in so many vehicles it is very difficult to switch the since you have to take off the intake manifold and then put it back to get the engine to run n see if the mis moves example:toyota sienna, so in this case you either test the wires or both to make sure once you install the intake manifold the job is done, thanks for sharing your thoughts, very good.
You can do that test of ignition coil so you can see if that ignition coil is bad or good before you change the ignition coil between 1-cylinder and 4-cylinder
@@konstantin-big every body does that including my self, this is to check them technically n no cranking engine, disabling fuel, n disconnecting other ignition coils n also taking out spark plugs, thanks for sharing
A rav 4 , 4X4, just done the engine, cam and crank sensor are all fine., ignition coils and spark plugs are fine , But no spark what could be the problem . please help
check crank shaft position sensor, mass air meter sensor n wires, if you have access to a scanner that has live data you can check if the crank sensor is counting the revolutions when the engine rotates, also the pcm, check that no wires were damaged during the engine job.
This is the best video about testing these Toyota 4pin coils. So well explained, like a good teacher.
Wow, thanks! for such a nice comment
Thanks for the video
thank for watching n sharing
Great ..thanks so much.
You are welcome! thanks for taking the time
Thanks so much

Ok
thanks bro,
this helps
thank you

At 0:55 that spark tester, is that a special spark tester???
What can we use If we haven't that spark tester???
Can we use a spark plug?????
it is a regular spark tester that you can find at any auto part store, yes you can use a spark plug instead
@@mairasan-ud5ih
OK
Thanks for the answer

Where are you located
I'm in NY
I have seen the acu diagram on your profile please send it to me sir i need it thank you,
where in my profile, can you specify how it looks
Where is the IGT CABLE CONNECTED
You can see on the picture
IGT=3=5V battery (-)
IGF=2=5V battery ( +) intermittent you can see that on 6:00
