2001 Town & Country EVAP System Fault: Trouble Codes P0442 and P0455 - Where Does the Rubber Hose Connect?

Model: 2001 Town and Country Fault Code: P0442 Posted: 2007-03-30 17:23

I recently discovered the check engine light is on, and a diagnostic scan at AutoZone revealed trouble codes P0442 and P0455. These indicate medium and large evaporative emissions system leaks. I previously installed an aftermarket gas cap, which I now believe was a mistake. Currently, there's a rubber hose with an L-shaped end hanging behind the driver's side wheel. I'm unable to determine where this hose should connect or what it's supposed to attach to. I took the vehicle to the used car lot where I purchased it — they only replaced the battery. Two days later, the check engine light returned on. Upon inspecting the battery installation, I noticed the fuse box cover was open and missing a relay; two others were partially pulled out of their sockets. The van is a 2001 Chrysler Town & Country LX base model with a 3.3L engine, front-wheel drive, and has accumulated 98,000 miles. I no longer trust the previous service providers and am seeking advice on how to properly diagnose and fix this issue. Specifically, where does that rubber hose go? Any guidance on EVAP system components or repair steps would be greatly appreciated. Also, note that in most U.S. states, a vehicle with these codes will fail smog inspections unless resolved promptly.

That's concerning — is the rubber end of the hose L-shaped? If yes, it likely connects to the Canister Vent Valve. Otherwise, it may be routed to the LDP (Liquid Drain Pump) or one of the two EVAP canisters located under the vehicle near the driver’s side. To confirm, you should raise the van and visually inspect all components in the driver's seat area — especially those beneath the floor pan. Codes P0442 and P0-than indicate significant leaks in the evaporative emissions system. If unresolved, your vehicle will fail smog inspections in most U.S. states. I recommend addressing this issue promptly to avoid future compliance problems. Let me know how it turns out once you've diagnosed or repaired it.
