1-Pin 2.2mm Knock Sensor Connector Pigtail OEM 90980-11166 / 7283-1015-10 – Toyota Lexus 2JZ-GTE / 1JZ / 3S-GTE
Direct OEM-specification replacement for the 1-pin 2.2mm waterproof knock sensor connector used on Toyota and Lexus performance and JDM engines. Cross-references Yazaki OEM numbers 90980-11166 and 7283-1015-10. Supplied as a pigtail with 15cm 18AWG wire and cable sleeve — ready for direct splice into the existing harness. The 2JZ-GTE uses a single-pin knock sensor connector; a corroded or damaged connector is a leading cause of P0325 and P0327 on 2JZ-powered vehicles, including engine swap builds where the original harness is shortened or modified.

Q: My 2JZ Supra has P0325 — is it the knock sensor or the connector?
A: P0325 on 2JZ engines is frequently caused by a damaged or corroded 1-pin connector rather than a failed knock sensor. The 2JZ knock sensor is a flat-response piezoelectric type — it rarely fails mechanically. On engine swap builds, the connector is often cut and re-spliced, creating a weak point. Replace the pigtail connector before replacing the $80–150 knock sensor.
Q: Why does the 2JZ use a 1-pin knock sensor connector?
A: Toyota’s 2JZ-GTE uses a resonant-type knock sensor with a single signal wire — the sensor body grounds directly through its mounting bolt to the engine block. This is different from flat-response (wideband) knock sensors used on modern engines, which typically use 2-pin connectors with a separate ground wire.
Q: Can I use this pigtail for a 2JZ engine swap?
A: Yes. This pigtail is specifically suited for 2JZ engine swap harness repairs. The 15cm wire length provides enough slack for a clean splice into the existing harness, and the cable sleeve provides professional-grade protection against heat and abrasion in the engine bay.
Q: Is the terminal pre-installed?
A: Yes. The terminal is pre-installed in the housing and the wire is pre-crimped — this is a ready-to-splice pigtail, not a bare connector kit.
