This code indicates that the Engine Control Unit (ECU) has detected an incorrect purge flow in the evaporative emission control system. The evaporative emission control system is responsible for preventing fuel vapors from escaping into the atmosphere. The purge valve is responsible for opening and closing to allow fuel vapors to flow from the charcoal canister into the engine to be burned.
Possible causes of this code include:
- Faulty purge valve
- Faulty vacuum lines or hoses
- Faulty canister
- Faulty ECU
To diagnose this code, a mechanic will need to inspect the evaporative emission control system and test the purge valve and other components.
Here are some steps that you can take to try to fix the problem:
- Check the vacuum lines and hoses for leaks or damage.
- Check the purge valve for proper operation.
- Check the charcoal canister for damage or leaks.
- If necessary, replace the faulty purge valve, vacuum lines, hoses, or canister.
If you are not comfortable performing these repairs yourself, you should take your vehicle to a qualified mechanic.
