I have a 02 Jeep Grand Cherokee and i recently got a check engine light on the dashboard, i got to Autozone and they gave me a code of P0442.
EVAP (Evaporative Emission System) small leak/no flow condition
The evaporative emission system is monitored.
1. - Defective or loose fuel cap
2. - EVAP canister or hose cracked-not connected
3. Purge or vent solenoid defective
4. Vacuum leak at engine
My jeep has got more than a 100,000 miles on it.
Please suggest if replacing the fuel cap will rectify this situation.
Also can someone suggest me of the best place to get my Jeep serviced at a nominal cost. I live in St Louis.
Thanks to one and all.
