HOP Crankshaft Position Sensor 90451442 Opel Old Sail Engine Speed Accurate Monitoring

Opel and Daewoo models use HOP 90451442 crankshaft position sensor; direct replacement for OEM 90451442 with broad compatibility. Monitors engine speed and crankshaft position and feeds ECU to control ignition and injection. Fits Opel and Daewoo models; effectively resolves rough idle, weak acceleration, starting difficulty, and stalling. If misfiring, erratic driving, or check engine light is on, sensor aging is the cause; replace early to avoid break-down.
