By sensing vibrations caused by abnormal combustion, it sends signals to the engine control unit (ECU) to adjust ignition timing accordingly. This helps maintain engine efficiency, reduce emissions, and protect internal engine components from damage caused by knocking. The sensor is engineered to meet the specifications required by BMW for the 318i, 318is, 318ti, and Z3 models, ensuring proper fitment and reliable operation.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed by the Facet 9.3120 Knock Sensor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEngine knocking or pinging noises during acceleration\u003c\/li\u003e\n\u003cli\u003eReduced fuel efficiency due to improper ignition timing\u003c\/li\u003e\n\u003cli\u003eCheck engine light triggered by knock sensor fault codes\u003c\/li\u003e\n\u003cli\u003eIncreased emissions from inefficient combustion\u003c\/li\u003e\n\u003cli\u003ePotential engine damage from prolonged detonation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the Facet 9.3120 ignition knock sensor on BMW 318i, 318is, 318ti, or Z3 models, ensure the engine is cool and the battery is disconnected to prevent electrical issues. Proper torque specifications should be followed to avoid sensor damage or improper operation. It is recommended to inspect the wiring harness and connectors for corrosion or damage before installation. Calibration or ECU reset may be necessary after replacement to clear fault codes and optimize sensor performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty Information\u003c\/h2\u003e\u003cp\u003eFacet manufactures the 9.3120 ignition knock sensor to meet OEM standards for durability and accuracy.
