Hello friends welcome to the ig garage channel today I am telling you how to fix p0134 02 sensor circuit no activity detected bank 1 sensor 1 so watch this video and learn how to fix it friends if you like this video then subscribe to the ig garage channel for more videos.

📺 Welcome to IG Garage!
In this video, we’ll explain the OBD-II Trouble Code P0134, which stands for:
"Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 1)"

❓ What is Code P0134?
The P0134 code means that the upstream oxygen (O2) sensor on Bank 1 is not sending any signal to the Engine Control Module (ECM).

Bank 1 refers to the side of the engine with cylinder 1.
Sensor 1 is the pre-catalytic converter sensor, important for monitoring and adjusting the air-fuel mixture.

When no activity is detected, it means the engine may not adjust properly for fuel economy or emissions.

⚠️ Symptoms of P0134:
🚨 Check Engine Light ON

🛻 Poor fuel efficiency

🛠️ Engine runs rough or misfires

🐌 Hesitation during acceleration

🌫️ Increased emissions and possible exhaust smell

🔍 Common Causes:
🧯 Faulty O2 sensor (Bank 1, Sensor 1)

🔌 Broken, shorted, or disconnected sensor wiring

🧪 Sensor heater circuit failure

🔥 Exhaust leak before the O2 sensor

❌ Faulty Engine Control Module (rare)

🛠️ How to Fix Code P0134:
🔍 Inspect sensor wiring and connector for damage or corrosion

🧪 Test the O2 sensor with a multimeter

🔄 Replace the O2 sensor if faulty

🔥 Repair any exhaust leaks before the sensor

📲 Clear the code with an OBD2 scanner after repairs

📍 Sensor Location:
✅ Bank 1, Sensor 1 is located:

Before the catalytic converter, typically in or near the exhaust manifold on the same side as cylinder 1.

Always refer to your vehicle’s manual for precise location details.

💰 Estimated Repair Cost:
O2 Sensor Replacement: ₹1,500 – ₹4,000

Wiring Repair: ₹500 – ₹1,500

Diagnostic Charge: ₹500 – ₹1,000

✅ Final Advice:
While the P0134 code might not cause immediate drivability issues, ignoring it can lead to poor mileage, rough performance, and potential long-term damage to the catalytic converter. Fix it early for best results!
