Chevrolet HHR Ignition Sensors

Carquest premium engine management products provide the right products for a wide range of domestic and import applications. Delivering the highest performance and durability under demanding conditions.

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:

• Delphi knock sensors help maximize engine performance with all fuels
• 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

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
