2373138U12 Nissan CAMSHAFT POSITION SENSOR, Price: 94.23$, Weight: 0.05kg

Engine Timing Signal Sensor for Reliable Performance

This important engine sensor helps the vehicle control unit know the exact position and speed of the camshaft. It is needed to manage fuel injection and ignition timing with high accuracy. When this signal is correct, the engine starts easier, idles smoother, and delivers better fuel economy. It is a small part, but it has a big job inside the engine management system.

⚙️ How This Sensor Works

The unit reads the rotation of the camshaft and sends an electrical signal to the ECU. Using this data together with the crankshaft signal, the system decides when to inject fuel and when to fire the spark. This keeps combustion balanced and helps reduce emissions. Modern engines depend on this communication for stable running and quick response.

What Happens If It Fails

If this sensor becomes weak or damaged, the engine may crank for a long time, misfire, hesitate, lose power, or suddenly stall. In some cases, the check engine light will appear and fuel consumption may increase. A faulty timing signal can also make starting difficult, especially when the engine is warm. Replacing a bad sensor restores proper timing control, smoother driving, and dependable engine operation. ✅
