engine light 2002 Dakota

I'm betting its P0455, which means large evaporative emission system leak. I just fixed my '01 3.9 Dakota. There were two splits in the evap hoses. The first one was at the green evap port. This hose is on the drivers side at the very front of the engine compartment. There is a little green fitting on a 5/16 vacuum hose. Mine was split right there. I cut off about an inch of hose and pushed it back on the port.
The second was on the charcoal canister under the truck on the driver's side in front of the fuel tank. Just crawl under there and you will find it. One of the large hoses on the canister was split. Again, I cut off an inch of hose and pressed the hose back on. No more P0455. By the way, just cycle your ignition on and off three times and the trouble code will display in the odometer, followed by "P-Done".

The printout from Auto Zone says:
Definition
BBEVAP (evaporative emission system) small leak/no flow condition.
Explanation:
The evaporative emmission system is monitored for it's ability to hold vacuum.
Probable Cause:
1. Defective or loose fuel cap.
2. EVAP canister or hose cracked or not connected.
3. Purge or vent solenoid defective.
4. Vacuum leak at engine.
I relpaced the fuel cap and inspected the hoses i can see.
Where is the vent solenoid located??
Other suggestions??
Thanks for any help you can give.

The '02 Dakota has OBDIII, not OBDI. Don't waste your time with AutoZone, you can read your codes off your odometer and look up the diagnostic trouble code yourself online. Just google the trouble code and "Dakota" and you will find the description. OBDIII is an industry standard - the a DTC code means the same thing regardless of vehicle manufacturer. It took me ten minutes to diagnose my evap issue. Believe me, they shove those vacuum lines on fittings without clamps and over time, the rubber dries out and cracks the hose.
Vent solenoid is behind the driver's side headlight. The hose that cracks is attached to a green service port that looks like a tire fill valve. The green service port is right over the power steering pump. It will crack there and under the truck at the charcoal canister as I said in my previous post.

our generation trucks including 3rd gen and most likely the 4th gen dakotas are OBD 2 (II), not OBD 3 (III)
