Parts for your 2017 Subaru Outback-Crank angle sensor

2017 Subaru Outback crank-angle-sensor (crankshaft position sensor) — purpose and servicing

Technical sources confirm the 2017 Subaru Outback does use this part. Subaru’s factory service information (STIS) and the 2015–2019 Outback service manual list a Crankshaft Position Sensor (often colloquially called a crank-angle sensor) for both the 2.5‑litre FB25 and 3.6‑litre EZ36 engines, with diagnostic coverage for DTCs P0335–P0339. OEM parts catalogues for that model year also show the sensor as a distinct, replaceable component. So yes, it’s fitted and it’s critical.

On this Outback, the crank-angle sensor feeds the ECU with precise crankshaft speed and position data. The ECU then times fuel injection, coil firing, and coordinates with cam sensors for variable valve timing and misfire detection. Without a clean, consistent signal, the engine may crank but not start, or run poorly because the timing strategy loses its reference.

It isn’t a scheduled service item, but it benefits from a bit of preventative care. During routine servicing under the bonnet, it’s smart to check the wiring harness for chafe, oil contamination, or loose connectors, and avoid blasting connectors with high-pressure water. Heat and vibration are the usual long‑term stressors, oil leaks can also wick into connectors and upset the signal.

• Common symptoms of a failing sensor: hard starting or no start, intermittent stalling when hot, rough running, uneven idle, and a Check Engine Light with codes like P0335.
• If those appear, proper diagnosis matters: confirm power/ground integrity, inspect the connector, and scope the signal where possible before ordering parts.

Replacement on a 2017 Outback is typically straightforward: disconnect the battery, gain access to the sensor at the engine block where it reads the crank reluctor, unplug, remove the retaining bolt, swap the unit (and O‑ring if applicable), then refit and clear codes. Most techs allow 0.5–1.0 hour. Use quality OEM or reputable-brand parts, cheap sensors can cause intermittent faults that are hard to chase.

Lifespan varies widely, but many run well past 150,000–250,000 km. If the ECU has logged related DTCs and the harness checks out, replacing the crank-angle sensor is a sensible fix. After installation, a quick road test and a scan for live RPM and misfire counters helps confirm the new sensor is doing the job.

Popular questions about 2017 Subaru Outback crank-angle-sensor

Does a 2017 Subaru Outback have a crank-angle sensor?
Yes. Subaru refers to it as the Crankshaft Position Sensor (CKP). It’s fitted to both the 2.5‑litre FB25 and 3.6‑litre EZ36 engines and is covered in the factory diagnostics with codes such as P0335.

Where is it located, and is replacement easy?
It’s mounted to the engine block where it reads a toothed reluctor on the crankshaft. Access is generally from the top/front area with minor intake ducting out of the way. For most home mechanics, it’s a simple remove‑and‑replace job taking about 20–45 minutes if access is clear.

Is it safe to drive with a faulty crank-angle sensor, and what does it cost to replace?
Not really. A failing sensor can cause sudden stalling or a no‑start, which isn’t ideal on Kiwi or Aussie roads. Expect parts to range roughly from AUD/NZD $150–$300 for OEM (less for good aftermarket), plus 0.5–1.0 hour labour.
