The P0496 DTC code is a generic code which applies to all vehicle makes. A quick search on the 'net shows that this code seems to be more common with GM

SOURCE: I have a 2005 cadillac cts with 90,000 miles and

I've been having hesitation with shifting for the past 3 years. been in the shop 6 times (its a 2006 CTS with 78,000kms on it).
First they replaced the torque converter. That fixed the symptoms for 6 month. then they replaced the ****** under warranty. next time it was software. next time I'm not sure what they did to fix it. This time they blamed it on timing chains. After being in the shop for 8 weeks, I picked it up today and it worked great, except the check engine light came on, drove it straight back to the dealer. they took it for a test drive and it broke down on the highway. had to be towed back in.

My guess is you have the "stretched" timing chain issue that can occur on the Cadillacs. It might be covered by warranty, or if your SOL like me... not covered under warranty. Right now I'm fighting with GM Canada and the local GM dealer to fix this under warranty since it started under warranty to begin this.

What does a po496 code mean? why is engine light on? When I purchase a gas cap will this solve the problem? How can i fix it without seeing a dealer? 2006 cadillac cts 3.6 engine

The code insinuates that your purge valve has problems and probably needs to be replaced. Rather difficult to explain the repair but I did manage to find what you need to do on video.

Check engine light up


This DTC tests for undesired intake manifold vacuum flow to the evaporative emission (EVAP) system. The control module seals the EVAP system by commanding the EVAP canister purge valve Closed and the EVAP canister vent valve Closed. The control module monitors the fuel tank pressure (FTP) sensor to determine if a vacuum is being drawn on the EVAP system. If vacuum in the EVAP system is more than a predetermined value within a predetermined time, this DTC sets.

Unfortunately not. This vehicle has a very sophisticated CPU and the old age tricks will not work on this particular design. You will need to gain access and allow a professional GM tech to pull the Cadillac codes. An ordinary code reader may miss the exclusive Cadillac codes that may be stored at any given time.

A certified GM/Cadillac code reader will be your best bet..

2007 cadillac cts 3.6 motor...engine stalls. runs slightly rough during start up and then will die very occasionally taking off, hesitates and "jumps" between 40 to 50 mph. Does not write to code so...

CTS are very sensitive to problems with the hose between the air filter box and the intake. If it is not on good or leaks, it will cause the car to run rough, or die immediately after starting.
