Parts for your 2011 Subaru Exiga-Crank angle sensor

2011 Subaru Exiga crank angle sensor — what it does and when to replace it

Yes, the 2011 Subaru Exiga does use a crank angle sensor (commonly called the crankshaft position sensor). Technical sources that identify it on this model include the Subaru Factory Service Manual for the YA-series Exiga (engine diagnostics sections listing DTCs P0335/P0336) and the Subaru parts catalogue (FAST), which lists a “Sensor – Crankshaft Position” for YA-series Exiga variants, with part numbers that vary by engine code (e.g., common EJ applications show 22053AA053 or supersessions). If it’s an EJ20/EJ25-powered Exiga, this sensor is fitted at the front of the engine near the crank pulley/alternator area and reads a toothed reluctor on the crank.

On the 2011 Exiga, the crank angle sensor feeds the ECU precise crankshaft position and speed. That lets the ECU fire the injectors and coils at the right moment, manage AVCS timing on applicable engines, and keep cold starts and idle nice and smooth. If the sensor signal drops out, the ECU loses its place—starting becomes a chore or the engine can stall, and the check engine light will come on.

They’re not a scheduled replacement item, but they do live a tough life under the bonnet. Oil mist, heat, and vibration can age the plastic body and O-ring or corrode the connector. Owners often see these tell-tales when the sensor is on the way out:

• Hard start or no start when hot, intermittent stalling
• Rough idle or momentary loss of power
• Check engine light with P0335/P0336 codes

Replacement is straightforward on most EJ-equipped Exiga models: disconnect the battery, unplug the sensor, remove the single retaining bolt, wiggle the sensor out, lightly oil the new O-ring, seat it squarely, and refit the bolt. Typical Subaru torque for the retaining bolt is around 8–9 N·m. The air gap isn’t adjustable—just ensure the mounting face is clean and the sensor is fully home. Use an OEM or high-quality aftermarket unit and keep the harness clipped away from the alternator and ignition leads to avoid electrical noise.

As part of routine servicing, it’s worth a quick look for oil seepage around the sensor, green crust on the connector pins, and damaged loom insulation. If the vehicle’s had front-engine work (timing belt on EJ models, accessory belts, or front seal jobs), double-check the sensor plug is secure. A clean connector, good engine grounds, and a healthy battery often prevent “ghost” crank sensor faults that show up as intermittent starting gremlins.

• Where is the crank angle sensor on a 2011 Exiga?
  On most EJ-powered Exiga models, it’s mounted at the front/top of the engine block near the crank pulley and alternator bracket. Look for a small two-wire sensor held by a single bolt, with its tip pointing at the crank trigger wheel.
• Can it be cleaned or does it need replacing?
  If the tip is just dusty, a gentle wipe can help, but internal failure or heat-soak issues won’t be fixed by cleaning. If you’re getting P0335/P0336 and the wiring checks out, replacement is the reliable fix.
• Is a crank angle sensor the same as a crankshaft position sensor?
  Yes—different name, same job. Subaru literature often uses “crankshaft position sensor,” while workshops in Australia and New Zealand frequently say “crank angle sensor.”
