Check evaporation charcoal cannister isn't cracked, pipe has not come off or has a seal leak etc. You should find the cannister inside the inner wing, and an air hose (normally about 1/4" diameter) goes from somewhere on the inlet manifold or throttle body to this cannister.

HOw do I reset the Gascap error message on my 2009 Dodge Grand Caravan?

if the problem has been fixed than the light will go out on its own after several drive cycles. Otherwise you can use a scan tool to clrar ghe code. You can also try disconnecting the battey but i would not recommend it as it can also reset other learned strategies that you dont want to reset. Once cleared if it comes back on than the ptoblem is still present and will need further test to solve and repair

Where milage gage is it says gascap. Put new gascap on and it still shows up

Emissions trouble codes need a number of drive cycles completed in order for the code and/or indicator lights to extinguish. The drive cycles can involve several hundred miles of driving, a number of starts, a combination of low and high speed driving.
Most of these codes can be manually erased with a code scanner tool without the need to wait for the drive cycles to complete.

I took my Aspen07 to the shop and they replaced the gascap with a factory gascap, cleared the codes and the gascap message is still on as well as the check engine light. Any suggestions?

the check engine light is most likely evap system large leak which is what causes the gas cap light it probably needs a nvld pump or it has a leaking evap tube under th vehicle.

Gascap fault in odometre on.Mill light on.PO457 fault code.How can I fix this.

That code is associated with the EVAP system. Check to make sure the fuel cap is fitted properly and not damaged. If need be replace it. If the cap is fine then you need to inspect the EVAP system to make sure all hoses are in good condition, not cracked, and fitted properly. Next check the EVAP canister to make sure it is not damaged. Lastly, if all those things check out you'll need to replace the EVAP solenoid sometimes referred to as the purge solenoid. Good luck.

I have a 2008 Dodge Caravan. My gascap was loose

The light has to be actively turned off because the code will not necessarily clear itself. Sometimes it can be done by disconnecting the battery for an hour. If that doesn't work, it'll have to be done with a garage's scan tool.
