Parts for your 2019 Subaru Outback-Crank angle sensor

2019 Subaru Outback crank-angle sensor (crankshaft position sensor)

Based on Subaru’s factory technical information for the 2019 Outback (FB25 2.5L and EZ36 3.6L), the vehicle is fitted with a crankshaft position sensor, not labelled “crank-angle sensor” in Subaru literature. The function is effectively the same. Subaru’s Service Manual and OEM parts catalogue list it as the Crankshaft Position Sensor (CKP), and engine diagnostics refer to related DTCs P0335/P0336 for signal issues. Those sources confirm it’s a required input for the ECU on MY2019 Outback models.

On a 2019 Subaru Outback, the crankshaft position sensor’s job is to report crank angle and rotational speed so the ECU can time fuel injection and spark perfectly. It also helps the ECU sync with the camshaft sensor for variable valve timing and accurate misfire detection. Without a clean CKP signal, the engine may crank but not start, or it might stumble and cut out. The sensor reads a toothed reluctor attached to the crank, producing a precise pulse pattern the ECU recognises at all revs and loads.

There’s no scheduled replacement interval for the CKP on this model, it’s a fit-and-forget part unless fault symptoms arise. As part of major servicing, it’s smart to visually check the sensor body and connector for oil contamination, damaged wiring or loose retaining hardware. Keeping the connector clean and seated firmly under the bonnet helps avoid intermittent dropouts, especially in wet or dusty Aussie and Kiwi conditions. If replacement is needed, use a genuine or well‑known aftermarket unit and a new O‑ring. Disconnect the battery, unplug the connector, remove the single retaining bolt, swap the sensor, lightly oil the O‑ring, refit, and torque to the spec in the Subaru Service Manual. Afterward, clear any stored DTCs and road test, the ECU will relearn automatically over a few drive cycles.

• Common signs of trouble: long crank/no‑start, sudden stall, rough idle, poor fuel economy, and a check engine light with codes like P0335/P0336.
• Diagnostic tip: confirm power, ground and signal integrity at the connector before condemning the sensor, wiring faults are common.
• Good practice: avoid striking or prying near the reluctor, a bent or contaminated trigger wheel can mimic a bad sensor.

FAQs

Does a 2019 Subaru Outback have a crank‑angle sensor?
Yes. Subaru calls it the crankshaft position sensor (CKP). It performs the same role as a “crank‑angle sensor” by reporting crank angle and speed so the ECU can control spark, injection and VVT. This is documented in Subaru’s Service Manual and parts catalogue for the 2019 Outback.

Where is the crankshaft position sensor located?
It’s mounted to the engine block reading a toothed reluctor on the crank. Location varies slightly by engine: on the FB25 it’s mounted near the rear of the block/bellhousing area, while on the EZ36 it’s positioned toward the front timing cover region. Access is straightforward with basic hand tools.

Is there a service interval for the sensor?
No fixed interval. During major services, it’s wise to inspect the connector and loom, check for oil leaks, and ensure the retaining bolt is snug. If faults or DTCs appear, test the circuit and replace the sensor if confirmed faulty.
