Question PLEASE HELP - How to Read a blinking Service Engine Soon Light Soon

PLEASE HELP - Okay, I found out how to get to where the Service Engine Soon Light will blink whatever error code made it come on in the first place. Problem is I am having difficulty deciphering the blinking light code. I recorded the sequence on video and uploaded it to youtube. If you can decipher the code, please let me know and thank you.

The video runs for about 2 minutes. I am not sure at what point it starts repeating the code.

You have an evap purge issue, probably the solenoid but you need to look into that before you swap it out.

The light blinks slowly 10 times after this the code kicks in with 4 fast flashes followed by a slight gap followed by 5 fast flashes then a gap then another 5 fast flashes. This gives you the code of PO455. The service light then blinks slowly 10 times and then quickly for 4 times, then a slight gap then another 4 times fast then a slight gap then a single flash. This gives you the code PO441. The PO441 code = EVAP control system purge flow monitor. The PO455 code = EVAP canister purge control solenoid valve. I hope this makes sense to you and helps you to understand how to read the code

this isnt one of those codes that can be caused by a loose gas cap?

A loose gas cap will give a code for an evap leak, but checking or changing the cap wouldn't hurt.

Thank you for explaining how to read the code. You saved me the effort of asking that. Thanks.

UPDATE - HAPPY ENDING

I thought I would just update this thread with what I discovered. Apparently the CEL/SES light was triggered by a disconnected hose. When I was checking the AT fluid, I inadvertently disconnected the hose. After reconnecting it, the warning light disappeared!!!
