I have the P0456 on my dodge caravan sxt 2007 with the keys.


http://www.obd-codes.com/p0456

This is usually caused by a gas cap that was not put on properly after a fill up. If this is the case then simply tighten the gas cap and the check engine light should go out in a few days with regular driving or reset with a code reader. You may have to replace the gas cap if the code remains. be sure to get the correct cap.

Check the link above for further tests.

Engine light shows a code P0456 (small evap leak) on 2005 Grand Caravan. Replaced gas cap but engine light stays on.


It is likely a leaky hose in the evap system. The chemicals passing through the hose cause it to become brittle, causing cracking. Take a look at this instruction to see if it helps:

P0456 is Evap Emission control small leak detected.
P0522 Engine oil pressure sensor low voltage.
The first code could be related to a loose, defective, or missing gas cap.
The second code, could be a defective sensor but you will need to confirm. Check oil level and condition first then onto the sensor and related wiring.

Check all of your EVAP lines and the charcoal canister. Also check the lines and overflow line from the gas cap to the gas tank.

2005 dodge grand caravan has check engine light code PO507


RE: Check Engine Light

The check engine light may come on for several reasons.

It is not necessary to worry as it may be as simple as putting the gas cap on without fully clicking it shut!. If this is the case it will go away by itself in about a week at most!
You can take your car to an auto parts store to have them run a diagnostic (Some will do this for free).
If your car is running fine, re-tighten the gas cap, give it a week or have it diagnosed if you still feel uncomfortable with it.
