Standard Ignition KS94 ignition knock (detonation) sensor for the 1995-2000 Toyota Tacoma 4-cylinder 2.4L or 2.7L and other vehicles detects engine knock. It sends that signal to the engine computer, which can adjust ignition timing in response.
A failing knock sensor can show up as a check engine light, pinging under load or reduced power. Before you replace the sensor, rule out damaged wiring or a loose connector, because wiring problems can trigger a similar light.
The vehicles it fits include the 1992-1995 Toyota 4Runner V6 3.0L and the 1996-2000 4Runner 4-cylinder 2.7L, plus the 1993-1994 Toyota T100 V6 3.0L and the 1994-1998 T100 4-cylinder 2.7L.
