Parts for your 2019 Subaru Xv-Crank angle sensor

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

Yes — the 2019 Subaru XV (Crosstrek) with the FB20 petrol engine uses a crank-angle-sensor, more commonly called the crankshaft position sensor (CKP). This is documented in Subaru’s factory service manual for the 2018–2020 XV/Crosstrek (Engine Diagnostics section listing DTCs P0335–P0339 for the CKP circuit), Subaru’s Technical Information System (STIS), and OEM parts catalogues for the FB-series engines that specify a CKP sensor fitted to the block.

The CKP is the ECU’s timekeeper. It reads a toothed wheel on the crankshaft and tells the engine computer exactly where the pistons are and how fast they’re spinning. That timing data is used to trigger fuel injection and spark with millisecond precision, and to keep the cam timing in sync with the crank via the cam sensors. Without a healthy crank-angle-sensor, the XV can be hard to start, run rough, or not run at all.

When these sensors start to go out, they often play up when hot, cause intermittent stalling at lights, or log a check-engine light with codes like P0335. Wiring issues, heat, vibration, and metallic debris on the sensor tip can all contribute to faults.

• Typical symptoms: long crank/no start, random stalling, misfire feeling, uneven idle, poor fuel economy, and a CEL with CKP-related fault codes.
• Where it lives: mounted to the engine block, reading a reluctor/tone wheel on the crankshaft, access varies but is generally straightforward with basic hand tools.

As part of regular servicing, the CKP isn’t a scheduled replacement item. It’s “inspect and rectify if faulty.” For an XV owner or workshop, smart maintenance means checking the connector and loom for chafing, ensuring the sensor mount is clean and snug, and scanning for stored or pending codes if any drivability gremlins appear.

Replacement is typically simple: disconnect the battery, unplug the connector, remove the retaining bolt, ease the sensor out, lightly oil the O-ring on the new OEM-quality sensor, install and torque to spec, reconnect, then clear codes and test drive. No special programming is normally required, the Subaru ECU learns the signal on the fly. If a CKP fault persists, inspect the reluctor wheel and verify power/ground/signal at the plug before condemning the new part.

Using a genuine or top-tier aftermarket CKP sensor is worth it — cheap units can cause intermittent faults that are maddening to chase. A clean install, tidy wiring, and a quick scan-tool check will keep the XV happy for plenty more kilometres.

FAQs

What are the signs of a failing crank-angle-sensor on a 2019 Subaru XV?

Common signs include long cranking or a no-start when hot, sudden stalling at idle or while coasting, rough running, and a check-engine light. A scan tool may show P0335 or related CKP circuit codes. Intermittent issues that worsen with heat are especially telling.

Does the 2019 XV need a relearn after replacing the crank-angle-sensor?

Generally no. The Subaru ECU typically recognises the new CKP signal without a manual relearn. After installation, clear any stored codes, start the engine, and take a short drive so the ECU can validate the signal. If problems persist, double-check the connector, wiring, and sensor seating.

How much does a crank-angle-sensor replacement cost in AU/NZ?

As a guide, parts usually range from mid to high three figures for genuine, with labour often under an hour if access is good. Independent workshops may come in cheaper than dealer rates. It’s wise to opt for OEM or premium aftermarket to avoid repeat issues.
