9091905060 Toyota SENSOR, CAM POSITION, RH/LH, Price: 63.55$, Weight: 0.034kg

Engine Camshaft Position Sensor (Right/Left)

This engine sensor is needed so the ECU can “see” the exact position and speed of the camshaft on both bank sides (RH/LH). It helps the engine fire the spark and inject fuel at the correct moment, especially during cold starts, acceleration, and idle control. ⚙️

How It Works

The sensor reads a trigger wheel on the camshaft and sends a clean timing signal to the ECU. Using this signal, the ECU synchronizes ignition timing and fuel injection sequencing. On many Toyota engines it also supports variable valve timing operation, keeping power smooth and emissions low. 🔧

Why This Part Matters

Accurate cam feedback improves throttle response, fuel economy, and stable idle. It also prevents misfires caused by incorrect cylinder timing reference. ✅

If the Sensor Fails

A faulty unit may cause hard starting, rough idle, hesitation, poor fuel mileage, check engine light, misfire codes, and sometimes limp mode. In worst cases the engine may stall or crank without starting. Replacing a weak cam sensor early avoids catalyst damage from unburned fuel. 🚗
