Hyundai Crankshaft Position Sensor 39310-02600 SU9782 Stable Signal

Hyundai/Kia crankshaft position sensor, directly replacing OEM 39310-02600; highly versatile; fits Hyundai Elantra, Sonata, Tucson, and other models. Core function is to monitor crankshaft speed and position, sending signals to the ECU to control ignition timing and fuel injection; helps resolve startup difficulties, weak acceleration, engine vibration, and sudden stalling. If the vehicle occasionally fails to start or exhibits obvious misfire during driving, the sensor aging may be the cause; replace promptly.
