Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Purge Valve

Tools Required: Socket set, multimeter, pliers

Locate the purge valve, typically found near the engine or on the intake manifold.
Disconnect the electrical connector and the vacuum line from the purge valve.
Use a multimeter to check for continuity and correct voltage at the connector while the engine is running.
If the purge valve is faulty, remove it using a socket set and install a new one, ensuring proper orientation.
Reconnect the vacuum line and electrical connector.

3. Inspect and Replace Fuel Cap

Remove the fuel cap and inspect the rubber seal for any cracks or damage.
If the seal is compromised, replace the fuel cap with a new, OEM part to ensure a proper seal.
Reinstall the fuel cap, ensuring it clicks securely.

4. Perform Smoke Test

Connect the smoke machine to the EVAP service port.
Activate the smoke machine to check for leaks in the EVAP system.
Inspect all hoses, connections, and the EVAP canister for smoke escaping.
Repair or replace any components that are leaking.

5. Clear Codes and Test Drive

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored trouble codes.
Start the vehicle and take it for a test drive to ensure the check engine light does not reappear.
