Parts for your 2015 Subaru Exiga-Crank angle sensor

2015 Subaru Exiga crank-angle-sensor — what it does and when to replace it

Technical sources confirm the 2015 Subaru Exiga is fitted with a crank-angle-sensor (commonly called the crankshaft position sensor, CKP). The Subaru Exiga (YA-series) Factory Service Manual includes a dedicated “Crankshaft Position Sensor” section and diagnostics for DTCs P0335/P0336 for both FB25 and EJ20 engines. Subaru’s Electronic Parts Catalogue (FAST) also lists a CKP sensor assembly for 2015 Exiga variants under engine electrical (group 22, part code family 22056). That makes the crank-angle-sensor absolutely relevant to this model.

On the 2015 Exiga, the crank-angle-sensor keeps the engine management spot on. By tracking the crankshaft’s exact position and speed, it lets the ECU time spark and fuel with precision, which means smooth starts, decent fuel economy, and clean emissions. If the sensor signal drops out or gets noisy, the ECU can’t sync properly—hello rough running, random stalling, long cranks, or a dead stop with a check engine light.

During regular servicing, it’s worth giving the sensor and its plug a quick once-over. The sensor lives at the front of the engine near the crank pulley on FB engines, and by the bellhousing area on many EJ engines. Oil weeps, corrosion at the connector, or a damaged harness can all play havoc with the signal. A scan for stored codes like P0335/P0336 and checking live RPM during cranking can catch issues early. If the engine has had a front main seal leak or timing work, make sure the trigger wheel area is clean and the sensor face isn’t coated in sludge or metal fuzz.

• Common symptoms of a failing crank-angle-sensor:
  • Hard starting or no start when hot
  • Intermittent stalling, misfire, or surging
  • Tachometer drops to zero while cranking
  • Check engine light with P0335/P0336

1. Replacement tips: disconnect the battery, unplug the sensor, remove the single retaining bolt, and ease the sensor straight out. Lightly lube the O-ring on the new unit, seat it fully, and refit the bolt. Don’t over-tighten—small fastener, small torque.
2. Afterwards: clear any codes and verify clean RPM signal and smooth start-up. No relearn is typically needed, the ECU adapts on the fly.
3. Use quality parts: an OEM or top-tier aftermarket sensor with the correct connector and O-ring saves drama.

Popular questions

Where is the crank-angle-sensor on a 2015 Subaru Exiga?
On FB25-powered Exiga models it’s mounted at the front of the engine, reading a target on the crank pulley area. On EJ20 variants it’s typically near the bellhousing at the back of the block. Look for a small two-wire sensor held by one bolt, with the connector close by.

What are the signs the crank-angle-sensor is failing on an Exiga?
Hot no-starts, intermittent stalling at idle, a sudden loss of tach signal while cranking, and a check engine light with P0335/P0336 are the big giveaways. Some drivers notice random cut-outs that resolve after cool-down. A quick scan and basic wiring checks will usually point you in the right direction.

Do I need to program anything after replacing the sensor?
Generally, no. Once fitted, the ECU reads the new signal straight away. It’s good practice to clear stored codes, check live data for stable RPM during cranking, and take a short test drive to confirm there’s no misfire or stalling.
