1J0927807D ABS传感器 大众奥迪A3 防抱死制动系统替换

When your Jinbei 4G20/4G19 engine has starting difficulties, weak acceleration, rough idle or occasional stalling, typically the camshaft position sensor has aged or failed. This sensor normally transmits precise cam position to the ECU, coordinating ignition timing with crank sensor. This is a Delphi system original design; OEM numbers correspond to 4G20-4G19; fits Jinbei with 4G20/4G19 engines and Delphi fuel injection systems. Installation: ensure power is off, clean mounting holes to prevent oil or debris interference, torque screws per spec to avoid loosening or damage.
