Parts for your 2013 Subaru Outback-Camshaft sensor

2013 Subaru Outback camshaft sensor — what it does and when to service it

Based on Subaru technical sources, the 2013 Subaru Outback does use camshaft sensors. The Subaru Factory Service Manual for MY2013 Legacy/Outback (Engine Diagnostics covering DTCs P0340–P0349 and the Engine Wiring Diagrams noting “Camshaft Position Sensor RH/LH”) and Subaru parts catalogues for the FB25 2.5‑litre and EZ36 3.6‑litre engines all list camshaft position sensors as fitted components. On the 2.5 FB engine there’s a sensor on each cylinder bank, the 3.6 H6 likewise uses cam sensors on each bank.

On this Outback, the camshaft sensor feeds the engine control module precise cam angle data, letting it sync fuel injection and ignition with the crankshaft signal and run Subaru’s variable valve timing (AVCS) properly. That means smooth starts, decent fuel economy on the open road, and crisp throttle around town. If the signal goes missing or messy, the car can struggle to start, idle roughly, feel flat, or throw the MIL on.

Camshaft-sensors aren’t a scheduled replacement item in normal servicing, but they’re worth a look if there are drivability dramas or fault codes like P0340/P0341/P0345/P0346. Quick checks under the bonnet should include the sensor connectors for oil wicking, brittle insulation, or a loose retaining bolt, and confirming correct engine oil grade and level (AVCS performance and the cam signal quality both appreciate clean, correct oil).

Replacement is straightforward with basic tools. Under the bonnet, each sensor sits on the front of a cylinder head (locations differ slightly between FB25 and EZ36). Disconnect the battery negative, unplug the connector, remove the single retaining bolt, and ease the sensor out. Lightly oil the new O‑ring, seat the sensor squarely, and tighten the bolt to about 8–10 N·m (always check the Subaru service manual for your exact engine). Route the harness away from hot or sharp bits, reconnect, clear any codes, and verify with a scan tool that cam and crank signals sync cleanly. No special relearn is typically required on these models.

• Common symptoms: hard starting, lumpiness at idle, poor fuel use, hesitation, MIL on.
• Handy tips: keep oil changes on schedule, fix any oil leaks near the connector, and avoid aftermarket sensors of dubious quality—genuine or reputable OEM‑equivalent parts tend to last.

FAQs

How many camshaft sensors does a 2013 Subaru Outback have?
The 2.5‑litre FB engine uses two camshaft sensors, one per cylinder bank. The 3.6‑litre EZ engine also uses a sensor on each bank. Exact locations vary slightly by engine, but they’re accessible at the ends of the cylinder heads.

What fault codes point to a camshaft sensor issue?
Look for P0340/P0341 (Bank 1) and P0345/P0346 (Bank 2) for circuit and range/performance faults. Cam timing codes like P0011/P0021 may also appear if the ECM can’t properly correlate cam and crank signals, though those can stem from oil or AVCS issues too.

Can a camshaft sensor be cleaned instead of replaced?
If it’s just a bit oily, a gentle wipe and a fresh O‑ring can help. If the sensor has internal faults, cracked housing, or persistent signal errors after checks, replacement is the go. Always inspect the connector and wiring before condemning the sensor.
