Delphi AS10279 ignition knock (detonation) sensor for the 2011-2016 Hyundai Elantra 4-cylinder 1.8L, the 2014-2020 Elantra 4-cylinder 2.0L and other vehicles detects engine knock and sends that signal to the engine computer.
- Helps maximize engine performance with all fuels
- Helps protect against engine damage from pre-ignition knocking
- Calibrated for a wide variety of frequencies to detect shifts and give accurate signals
- Sealed to withstand humidity, salt spray and automotive fluids
- Ground-isolated design with a 2-wire shielded harness helps protect the signal from electromagnetic interference (EMI)
- Self-generating piezoelectric design requires no power to the sensor
Quick facts
- Part: Delphi AS10279 ignition knock (detonation) sensor
- Fits: 2011-2016 Hyundai Elantra 4-cylinder 1.8L, the 2014-2020 Elantra 4-cylinder 2.0L and other vehicles
- Condition: New
A failing knock sensor can show up as a check engine light, pinging under load or less power. A damaged wiring harness, a loose connector, worn spark plugs or poor fuel can bring on similar symptoms, so track down the cause before you buy a sensor.
Fits
The 2016-2019 Hyundai Sonata 4-cylinder 2.0L takes this sensor, as does the 2017-2020 Kia Optima 4-cylinder 2.0L, along with other Hyundai and Kia models. The Sonata takes one, and this listing is a single sensor. If your car is not named here, look it up in the "Vehicles it fits" section.
