2007 Cadillac Escalade ESV Knock Sensors

ACDelco GM Original Equipment Ignition Knock (Detonation) Sensors monitor the engine for pinging or spark knock, and are GM-recommended replacements for your vehicle’s original components. These sensors create a voltage signal based on the vibrations caused by erratic air/fuel mixture combustion; the engine control module uses these signals to adjust the ignition timing and air/fuel mixture. These original equipment ignition knock sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Product Features:

• Sends signals to the engine control module (ECM) to adjust timing
• Helps prevent damage to the engine caused by pre-ignition
• GM-recommended replacement part for your GM vehicle’s original factory component
• Offering the quality, reliability, and durability of GM OE
• Manufactured to GM OE specification for fit, form, and function

An ACDelco GM Original Equipment Ignition Knock (Detonation) Sensor monitors the engine for pinging or spark knock, and is a GM-recommended replacement for your vehicle’s original component. The sensor creates a voltage signal based on the vibrations caused by erratic air/fuel mixture combustion; the engine control module uses this signal to adjust the ignition timing and air/fuel mixture. This original equipment ignition knock sensor has been manufactured to fit your specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Product Features:

• Undergo the same stringent testing process as the original part
• GM-recommended replacement part for your GM vehicle’s original factory component
• Offering the quality, reliability, and durability of GM OE
• Manufactured to GM OE specification for fit, form, and function

Manufactured to meet or exceed OE requirements; Delphi Knock Sensors help maximize engine performance with all fuels; Delphi Knock Sensors prevent against engine damage from pre-ignition knocking.

Product Features:

• Flat frequency response allows the same sensor to be used on different engines and the sensor responds to knock frequencies higher than the primary frequency
• Delphi knock sensors prevent against engine damage from pre-ignition knocking
• Calibrated for a wide variety of frequencies to detect shifts, and adjust to provide accurate signals to help maximize engine performance
• Flat frequency response allows the same sensor to be used on different engines and the sensor responds to knock frequencies higher than the primary frequency
• Ground-isolated design with 2-wire shielded harness helps protect the sensor signal from electro-magnetic interference (EMI)
• Self-generating piezoelectric design requires no power to the sensor
