⚙️ Sensor Installation Blueprint
ENGINE CATALYTIC CONVERTER UPSTREAM (SENSOR 1)Exhaust Manifold (Engine Side) DOWNSTREAM (SENSOR 2)Exhaust Pipe (After Converter)
👨‍🔧 Mechanic's Installation Notes:

This is a COMPLETE SET (Upstream & Downstream). O2 sensors wear out at the same rate (typically 80k-100k miles).
Installation: Upstream sensors screw into the exhaust manifold near the engine. Downstream sensors screw into the pipe after the catalytic converter under the car.

Common Error Codes: P0131, P0171, P0420, P0430
Expert Recommendation: Replacing all sensors together ensures optimal engine performance and saves you from paying mechanic labor costs twice.
