Delphi knock sensors "listen" for a variety of knock frequencies under different operating conditions, to detect shifts and provide an accurate signal to the engine control module (ECM)
Delphi knock sensors help maximize engine performance regardless of fuel quality and reduce potential damage to internal engine components.
Extensive coverage
Manufactured to meet or exceed OE requirements and testing
Tips & Tools For The Repair
Helpful Tools: A Scraper, to remove carbon deposits on the engine; Intake Valve Cleaner, to clean the Intake Manifold; a Torque Wrench, to tighten the sensor(s) according to OE specifications.
Replace all Knock Sensors together while you already have the intake removed. Engines typically have one knock sensor per bank.
Old, brittle connectors often break during installation or removal - replace the corresponding Knock / Detonation Sensor Connector (found in the "Electrical-Connector" category) to prevent failure.
