Subaru 22060AA070 — Knock Sensor
Overview
Knock sensor Subaru 22060AA070 detects high-frequency engine knocking vibrations in the cylinder block and transmits voltage signals to the engine control unit. Features a 1-pin electrical connector, single M8x1.25 mounting bolt hole, and an internal piezoelectric ceramic element. Operating voltage is 12V. Construction combines a steel base with a heat-resistant plastic housing to protect internal circuitry against engine bay fluids and heat cycle fatigue. OEM reference number: 22060AA070. The sensor enables the ECU to adjust ignition timing instantly, preventing severe mechanical damage to pistons, valves, and cylinder walls caused by uncontrolled fuel detonation spikes.
Knock sensor Subaru 22060AA070 fits Subaru Forester SF model years 1997–2002, Impreza GC, GF, GD, GG model years 1998–2002, Legacy BD, BG, BE, BH model years 1998–2003, and Outback model years 1998–2003 fitted with 2.0L, 2.2L, and 2.5L EJ20, EJ22, and EJ25 four-cylinder petrol engines. Replacement becomes necessary when diagnostic code P0325 triggers the engine management warning light on the dashboard. Further signs of sensor failure include sluggish throttle response, sudden loss of power during acceleration, metallic pinging under heavy engine load, and elevated fuel consumption. Faults typically stem from age-related degradation of the piezo ceramic plate, contact pin oxidation, or thermal cracking of the plastic casing around the bolt ring.
