Keep ignition timing and fuel delivery precisely synced with the NTK Engine Crankshaft Position Sensor EH0310. It fits as a direct-fit replacement across a broad Subaru range — including the 2003-2006 Subaru Baja, 1998-2016 Subaru Forester, 1993-2015 Subaru Impreza, 1995-2015 Subaru Legacy and 2000-2015 Subaru Outback, plus the 2005-2006 Saab 9-2X — with the remaining applications under the Buyer's Guide tab.
- Core job: monitors crankshaft position and rotational speed, sending the signal the engine control module uses to manage ignition timing and fuel injection.
- Signs it may need replacing: hard starting or a no-start, stalling, misfires, hesitation, or an illuminated check engine light — if a failed crankshaft position sensor is the cause.
- Direct-fit: a direct-fit replacement for the listed applications.
Because these symptoms can have several causes, diagnose the fault before replacing so you install the right part the first time.
