Parts for your 2000 Subaru Legacy-Crank angle sensor

2000 Subaru Legacy crank-angle-sensor — what it does and how to look after it

Based on technical references, the 2000 Subaru Legacy does use a crank-angle sensor (Subaru commonly calls it the crankshaft position sensor). The 2000 Legacy/Outback Factory Service Manual (Subaru, Engine Diagnostics, DTC P0335–P0339) specifies the sensor, its signal to the ECU, and diagnostic steps. Workshop manuals for these models (e.g., Haynes for Legacy/Outback 2000–2009) include testing and replacement procedures, and OE supplier catalogues from Denso and NGK/NTK list a crankshaft position sensor for 2000 Legacy EJ engines. So yes—this part is absolutely relevant on the 2000 Subaru Legacy.

On the 2000 Legacy, the crank-angle sensor is the ECU’s timekeeper. It reads a toothed trigger on the crank and feeds the ECU the exact crankshaft position and speed. With that, the ECU fires the coils and controls fuel injection with the right timing. If the signal drops out, the engine can crank but not start, stall at idle, or throw a check engine light.

Typical signs the sensor or its wiring is on the way out include:

• Hard starting, especially hot, or intermittent no-start
• Random stalling or misfire without obvious cause
• Tachometer not flickering during crank and a CEL with codes like P0335

Location-wise, it’s a small, single-bolt magnetic pickup mounted at the front of the engine near the timing cover, reading a reluctor on the crank. Under the bonnet, look down towards the centre-front of the engine, it’s an easy visual once the intake ducting is out of the way.

There’s no scheduled replacement interval, as it’s a solid-state sensor. As part of a service on a 2000 Legacy, a savvy tech will:

• Inspect the sensor body and connector for oil ingress or corrosion
• Check the loom for chafing where it runs past brackets and the timing cover
• Scan live data for stable RPM during crank and idle, and check for stored DTCs

Replacement is straightforward: disconnect the battery, unplug the connector, remove the single bolt, and lift out the sensor. Fit the new sensor, seat it fully (air gap is fixed by design), and snug the bolt—firm hand-tight with a small ratchet is plenty. Clear any codes, then verify clean starts and steady idle. Use genuine or reputable OE-equivalent parts, cheap copies can give flaky signals and waste time. In Aussie and Kiwi conditions—heat, dust, and coastal humidity—keeping connectors clean and the loom properly clipped goes a long way to long-term reliability.

FAQs

Where is the crank-angle sensor on a 2000 Subaru Legacy?
It’s mounted at the front of the engine near the timing belt cover, reading a toothed wheel on the crank. From above, it sits centrally, secured by one small bolt, with a short wiring pigtail to the engine harness.

What are the symptoms of a failing crank-angle sensor on this model?
The usual giveaways are intermittent no-start when hot, random stalling, rough running, and a check engine light with codes like P0335. During cranking, the tacho may not twitch if the ECU isn’t seeing RPM.

Is it safe to drive with a bad crank-angle sensor?
Not really. The car can cut out without warning and may refuse to restart once heat-soaked. It’s best to diagnose promptly and replace the sensor or repair the wiring to avoid getting stranded.
