2013 Subaru Exiga Camshaft Sensor — What It Does and When to Sort It

Technical sources including the Subaru Factory Service Manual for the YA-series Exiga (MY2013, Engine Diagnostics section listing DTCs P0340/P0345 and Camshaft Position Sensor checks), the Subaru FAST parts catalogue for Exiga YA variants, and DENSO aftermarket catalogues confirm the 2013 Subaru Exiga is fitted with camshaft position sensing. The 2.5i EJ253 SOHC typically runs a single camshaft sensor, while the 2.0 DOHC turbo (GT) uses one on each bank. So yes, a camshaft sensor is absolutely relevant on this model.

On the 2013 Exiga, the camshaft sensor feeds the ECU real-time cam angle so it can fire the injectors sequentially, keep ignition timing tight, and manage Subaru’s AVCS (variable valve timing) where fitted. Teaming up with the crank sensor, it helps the engine start cleanly, idle smoothly, and pull well through the revs. When it plays up, you’ll often see a Check Engine Light, rough starts, flat spots, or higher fuel use. Common fault codes include P0340/P0341 (and P0345/P0346 on twin-sensor setups).

This isn’t a scheduled service item, but it’s smart to check it whenever you’re under the bonnet:

• Look for oil weeping around the sensor body or O-ring, and clean any grime off the connector.
• Inspect the harness where it passes the cam cover — heat and vibration can harden or chafe the loom.
• If you’re chasing misfires or hard starts, scan it first, live data and codes will point you in the right direction.

Replacement is straightforward with basic tools. Disconnect the battery earth, remove any covers for access, unplug the connector, and undo the retaining bolt (around 8–9 N·m on refit, always verify in the FSM for your exact engine). Lightly oil a new O-ring, seat the sensor squarely, and don’t over-torque the fastener. Fire it up, clear codes, and confirm cam/crank sync and AVCS targets in a quick road test.

Use an OEM or reputable brand sensor — cheap knock-offs can cause intermittent faults that are a headache to diagnose. For Exiga owners in Australia and New Zealand, a tidy sensor and clean connector can save heaps of grief, keep fuel economy on point, and make sure the seven-seater stays a relaxed, family-friendly tourer.

Where is the camshaft sensor on a 2013 Subaru Exiga?

On the 2.5i EJ253, it’s typically mounted at the front of the left-hand cylinder head near the cam sprocket. On the 2.0 DOHC turbo, expect one on each head. Some plastic covers may need to come off for access.

What are the signs the camshaft sensor is failing?

Hard starting, uneven idle, stumble on acceleration, poorer fuel economy, and a Check Engine Light. Scan tool codes like P0340/P0341 (and P0345/P0346 on twin-sensor engines) are the usual giveaways.

Is it safe to drive with a dodgy camshaft sensor?

Often the car will still run, but it may start poorly, lose power, or drop into a protective strategy. It’s best to diagnose and replace promptly to avoid roadside hassle and extra fuel burn.
