Reference for Diagnostic Trouble Codes ?

[CompUser]

Anyone know of an on-line lookup for DTC's? Got
a CEL yesterday afternoon, and local Autozone
pulled it for me..."P1491, Manufactorer
Control/Auxilliary Emissions Control". I'd like
to narrow it down a bit more before taking the
drive to dealer.

An '04 and I assume under 50k miles and in the US? Unless you left the gas
cap off, which would be a P0440 or 42, why care. It's a no cost to you
emissions failure.

Curiousity more than anything. I was going over
grounds the day before (found two with no star
washers, just bolt & ring terminal screwed down
on intact painted surface), and smearing
connectors with NoAlox...going back, I found one
connector that wasn't "clicked", which probably
caused the CEL.

Since Autozone will pull codes for free, a look-
up table would be nice, and not just for this
specific case...
