I have an 08 grand caravan that has been throwing a code for a small evap leak. It happens usually after I fill up so I'm going to start with a new fuel cap. If the fuel cap doesn't do the trick can I access the vapor recirculation line or will I have to remove the plastic from the wheel well?

 

The ESIM (Evaporative System Integrity Monitor) is very similar to the NVLD. However, the design of the ESIM has been simplified and unlike the NVLD the ESIM does not require a solenoid. Have the vehicle san for codes and clear them. Also check the powertrain control module and see if it is updated.
