Delphi Knock Sensor OE Replacement

The Delphi Knock Sensor is an OE replacement knock (detonation) sensor that helps your engine management system detect abnormal combustion. When the sensor picks up engine knock, it sends a signal to the engine control module (ECM/PCM). The module can then adjust ignition timing to protect the engine and keep it running well.

Key Features:

• Original equipment replacement design for reliable, accurate knock detection
• Converts engine vibration into an electrical signal for the engine control module
• Helps the ECM adjust ignition timing to reduce pre-ignition and detonation
• Supports engine performance, fuel efficiency and emissions control
• Built by Delphi, a long-time original equipment supplier to automakers worldwide

A failing knock sensor can cause a check engine light, reduced power, poor fuel economy or rough running. Replacing it with a Delphi OE replacement knock sensor helps restore proper engine protection and ignition timing control.
