Hi guys, some of you might of seen my other post regarding my CAT...and advised I shouldnt replace the CAT without finding out exactly what's wrong...So i went down to autozone and picked up this:

http://www.actron.com/whats_new_detail.php?id=20

After doing the computer scan it found 2 codes it said

"P1441" and "P1441 Pending" according to the manual the "pending" means its reoccuring or something? i dunno.

Here is a complete list of what it gave me:

2 Codes:

P1441
P1441 PD
MONITORS
3 INC
CATYLST
02 SENSOR
EGR
5 READY
MISFIRE
FUEL
COMP
SEC AIR
02 HTR


Not sure what to make out of this.....Please help. I don't know where to start

 

oh BTW its a 97 z28 SS camaro LT1. Im in CALI and i need to clear this code in order to pass smog.

 

BTW i just replaced this PART:

#11 in the diagram. I heard that could be causing the problem....

 

Ok well that's weird......after I tighted up my hoses around that EVAP area and reset the computer the light came back on but now instead of p1441 its giving me P0420

 

dont mean to high jack this thread, but is it bad to have deleted that #11 in that diagram?

this will tell you what the codes mean

The codes are on the site Mike linked. They're under GM codes. Here is a link to the GM site for code definitions:

The canister can start to leak the carbon into the lines and after sometime clog everything. http://shbox.com/1/evap_system.jpg

 

Shoebox has the LT1-specific codes lists in much easier to use and understand format. OBD-II codes are on a "tab" at the bottom:

P1441 usually means the purge solenoid is stuck open, or you hooked the purge solenoid vacuum lines lines up incorrectly (switched them).

P0420 means the after-cat sensor on the driver's side is indicating the cat is not working. If you have cats, swap the two after-cat sensor side-to-side. If the problem follows the sensor (P0430) its a a sensor problem. If the problem stays on the driver's side, its a bad cat or a wiring problem.
