anybody have an idea on why all of these codes pop up all at the same time --po135, 1406,1441,1655?

No clue why all of these would appear at the same time.
P0135 = O2 sensor heater circuit malfunction, Bank 1 sensor 1
P1406 = Egr Pintle Position Circuit
P1441 = Evap System flow during non purge
P1655= Evap Solenoid Control Circuit

Can anyone see the correlation between them all at the same time.

The Evap problems can be diagnosed separately from the EGR and the O2 sensor heater.

Unless there is some strange tie in at the PCM, IDK.
Or these wires are grouped together at the firewall connector and have dirty or bad connections.

They all have circuit 639 (pink wire) in common which is ignition voltage. There is a 20A fuse in the IP fuse panel for this circuit. It should be labeled Oxygen Sensor Fuse. Check this fuse and make sure it is in fact a 20A in it's place. We can continue to diagnose after you checked this.....

IP= Instrument Panel or Dashboard.
It is the small fuse holder with a door that you see when open the drivers side door and look at the Instrument Panel.
The easiest fuse holder to get to on the whole car.
Good Luck,
Hope it;s just a fuse.

I don't know about this code in particular, but most codes will clear themselves, if the problem is gone, after a certain number of drive cycles.
Would have to look up that code in your FSM to determine the number of starts and stops required to clear the light or if you have a code reader, then use it to clear the light..

Did the fuse blow again to indicate there is an actual problem in one of the 3 circuits involved with this fuse.?
You'll need to check it often to determine if there was a problem or just a glitch that caused the fuse to blow.

Agreed. Keep an eye on that fuse to make sure it doesn't blow again.....to get rid of the SES light, disconnect your battery overnight, then reconnect it in the morning. The codes will clear that way and the SES light will go off.
