Delphi AS10172 ignition knock (detonation) sensor for the 2003-2025 Toyota Corolla 4-cylinder 1.8L, the 2009-2010 Corolla 4-cylinder 2.4L, the 2019-2025 Corolla 4-cylinder 2.0L and other vehicles detects the vibration of engine knock and sends a signal to the engine computer. The sensor is tested and calibrated to OE standards.
- Helps maximize engine performance with all fuels
- Helps protect the engine from damage caused by 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 that helps protect the signal from electromagnetic interference (EMI)
- Self-generating piezoelectric design that requires no power to the sensor
Quick facts
- Part: Delphi AS10172 ignition knock (detonation) sensor
- Fits: the 2003-2025 Toyota Corolla 4-cylinder 1.8L, the 2009-2010 Corolla 4-cylinder 2.4L, the 2019-2025 Corolla 4-cylinder 2.0L and other vehicles
A failing sensor can show up as a lit check engine light, pinging under load or reduced power, although other faults can produce similar symptoms. With the engine off and cool, look over the sensor wiring and connector for cracks, corrosion or damage before replacing anything, and leave electrical testing to a shop.
