my '04 SL with 109k miles has been good to me....until today.

My check engine light came on, so I decided to stop by at Autozone to have it scanned. The scanner showed the code P1402. I followed the worker back inside and he prints out a long list of possible issues. (WTF?! I was hoping I'd get one or two issues but didn't expect it to be 8!) Here is what the printout states:

I don't have access to a scanner or a camera at this time so I had to type up exactly how the print out looks like. I am hoping someone can chime in and give me few tips. I have no clue where to start. Thanks in advance

 

P1402 _EGR Valve.

Had work performed on my max about 3 weeks ago for this same code.

Good case scenario - - > replace the EGR valve

Bad case scenario - - > replace the EGR valve and both cats.

Here is the TSB
