🔍 What is P0443?
P0443 means that the Engine Control Module (ECM) has detected a problem in the Evaporative Emission Control System (EVAP) purge valve circuit.

💨 What is the EVAP System?
The EVAP system prevents fuel vapors from escaping into the atmosphere. It stores and controls the release of fuel vapors into the engine for combustion.

⚠️ Why Did P0443 Get Triggered?
Your car’s computer detected an issue with the electrical circuit controlling the purge valve, leading to the check engine light turning on.

🔧 Common Root Causes of P0443:
🔹 Purge Valve Stuck Open or Closed – Prevents proper vapor flow.
🔹 Open Circuit in Purge Valve Wiring – Can cause communication failure.
🔹 Damaged, Burnt, Shorted, or Corroded Connectors – Interrupts the circuit.
🔹 Failed or Failing PCM (Powertrain Control Module) – The engine control unit may be faulty.
🔹 Blown Fuse or Faulty Relay – Electrical components may not be receiving power.
🔹 Vacuum Leak – A leak in the EVAP system can trigger the code.

🛠 How to Fix P0443?
✔ Scan for Additional OBD Codes – Check for related EVAP system codes.
✔ Inspect the Purge Valve – Test for proper operation and replace if necessary.
✔ Check Wiring and Connectors – Look for signs of corrosion, damage, or disconnections.
✔ Test the EVAP Circuit – Ensure voltage and ground connections are intact.
✔ Inspect the PCM and Fuses – Replace blown fuses or faulty relays.
✔ Check for Vacuum Leaks – Use a smoke test to detect leaks in the EVAP system.
