Couple of questions:
Is the car modified?
Are you the original owner?
This is definitely an Evap system code, if you answered "Yes" to either of the questions above check the ECM wiring first. ECM is located behind the glove box against the passenger side A pillar. Look for loose wires in the ECM harness. I've seen previously modified cars that had taps into the harness connectors that were either shorted out, or loose that caused this code.
If the ECM wiring is fine check the following components as each can cause the code:
• Purge VSV (This is located under the intake manifold on the driver's side, it is blue & black, make sure the connector is plugged in securely and the wires are good, check that both purge lines are connected securely.
• Purge lines (These are the lines connected to the VSV, make sure they are connected securely on both ends and have no leaks or cuts).
• Connector/Wiring harness (Purge VSV - ECM) (As mentioned previously, check these harnesses & connections)
• Leakage from the EVAP system (may need to have this taken to a shop to perform a smoke test on the EVAP system to make sure there are no leaks.)
• ECM Issue (worst case, needs an ECM)
