2005 dodge caravan engine light code p 441

You always check for codes & resolve those
issue first,when ever a check light comes on.

P0441 indicates incorrect purge flow. You could have a problem with the purge valve, cannister, and/or vacuum lines.

When "check engine" litgh tun on, the PCM (computer) is warning that some fault code is stored there. Autozone could scanned your PCM and show exactly what fault codes is there; if your O2 sensors was replaced, I assuming that they can see this codes... so, they reset and delete all codes stored there? Scanned the PCM after this change?

Keep us updated-

is the check engine light blinking? if so have it tested for codes, Kragen auto and others do this test for free, just ask for a OBD2 fault code test. let me know the results and we can work from there.

Cycle the key on, off, on, off. on. Then count the flashes 12 is normal 55 is end of sequence

as long as the engine light is not flashing u will be fine to drive home.

3.3 engines has the egr valve with transducer.you have to replace the whole unit. code p0406 what its trying to tell you your egr valve circuit is short to ground.it has failed .

p0456--emission control system leak(verysmall) leak, check all hoses to emission controls, cylinder 3 missfire detected. could be plugs, wires, or coil.this is code p0303,

The check engine light on means there is a code stored in the ECM. You will have to have the OBD II system scanned and cleared. The other problem is probably just a blown fuse. If you need more help get back to me.
