⚠️ Common Symptoms of P0045:
🚨 Check Engine Light ON

🐌 Loss of engine power

🌀 Turbo not engaging or boost pressure too low

⛽ Increased fuel consumption

🧯 Engine hesitation or slow acceleration

💨 Black smoke from exhaust (in some cases)

🔍 Common Causes of Code P0045:
🔌 Faulty turbo/supercharger boost control solenoid or actuator

🔧 Open or shorted wiring in the boost control circuit

⚠️ Loose or corroded connectors

🧠 Malfunctioning Engine Control Module (ECM)

🛠️ Stuck turbo wastegate or internal turbo failure

🛠️ How to Fix Code P0045:
🔍 Inspect wiring and connectors to the boost control solenoid – clean or replace as needed

🔄 Replace the boost control solenoid or actuator if defective

🧪 Test the wastegate operation – ensure it moves freely

⚡ Check voltage and ground supply to the solenoid using a multimeter

🧠 Test the ECM output and update software if needed

✅ Clear the code and take a test drive

📍 Component Location:
The boost control solenoid/actuator is usually located near the turbocharger on the exhaust manifold or intake piping.
Follow the vacuum or electrical lines from the turbo to locate it easily.

💰 Estimated Repair Cost (India):
🔧 Boost Control Solenoid/Actuator: ₹2,000 – ₹6,000

⚡ Wiring Repair: ₹500 – ₹1,500

👨‍🔧 Mechanic Labor: ₹800 – ₹2,000
