It cross-references Standard Ignition KS395 for the same application. Delphi validates and calibrates its sensors to OE standards, helping ensure consistent signal output for Chevrolet Cruze and Chevrolet Sonic fitments. If you are replacing a faulty knock sensor on a 2011-2015 Chevrolet Cruze, a 2016 Chevrolet Cruze Limited, or a 2012-2018 Chevrolet Sonic, AS10321 provides the correct connector style, terminal count, and screw-mount configuration.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eKnock sensor fault codes\u003c\/li\u003e\n\u003cli\u003eAudible pinging or detonation under load\u003c\/li\u003e\n\u003cli\u003eIncorrect ignition timing caused by poor knock signal input\u003c\/li\u003e\n\u003cli\u003eReduced engine performance from inaccurate sensor readings\u003c\/li\u003e\n\u003cli\u003eCheck engine light concerns related to knock sensor circuit issues\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify connector shape, terminal count, and mounting style before installation.
