Volkswagen Jetta 2V/Wuling B15/Baojun 730 Crankshaft Position Sensor HOP 03C906433A Precise Signal Output

If your vehicle experiences starting difficulty, weak acceleration, unstable idle or sudden engine shutdown, crankshaft position sensor aging or damage may be the cause, hindering ECU from accurately obtaining crank speed and position. Properly functioning sensor continuously monitors crank angle and engine speed and transmits precise signals to the computer to ensure correct ignition timing and fuel injection. This HOP brand crankshaft position sensor corresponds to OEM 03C906433A; fits VW Jetta 2V, Wuling B15 and Baojun 730. Installation ensures sensor gap to timing ring is within standard (0.5-1.5 mm) and bolts are tightened to prevent looseness or poor contact that could cause signal interference.
