Parts for your 2016 Subaru Outback-Camshaft sensor

2016 Subaru Outback camshaft sensor: purpose, service tips, and common questions

Yes, the 2016 Subaru Outback uses camshaft position sensors. Both the 2.5i (FB25) and 3.6R (EZ36) engines are fitted with them. This is confirmed by Subaru’s Factory Service Manual for the 2015–2017 Outback models, which details diagnostics for DTCs like P0340/P0341 (camshaft position sensor circuit), and by Subaru’s genuine parts catalogues listing camshaft position sensors for these engines. These technical sources establish the part as standard equipment on this model year.

On the 2016 Outback, the camshaft sensor tells the engine control unit exactly where the camshafts are in their rotation. That timing info is used to fire the injectors in sequence, trigger spark at the right moment, and control Subaru’s variable valve timing (AVCS). The result is easy starts, smooth idle, decent fuel economy, and clean emissions. When the signal goes missing or noisy, the car can get grumpy fast.

Typical symptoms when a camshaft sensor is on the way out include:

• Check Engine Light with codes such as P0340, P0341, or bank-specific variants on the 3.6R
• Hard starting, occasional stalling, rough idle, flat spots on accel
• Higher fuel use and reduced power

There’s no scheduled replacement for the cam sensor on the Outback, it’s a “replace when faulty” item. As part of routine servicing, it’s smart to pop the engine cover, check the sensor connectors on the cylinder heads, and look for oil weep or brittle wiring. Oil intrusion or a loose connector can mimic a failed sensor.

When replacement is needed, use an OEM-quality sensor and a fresh O-ring. With the battery negative disconnected and the engine cool, the sensor can be accessed at the front of each cylinder head (FB25) or on the heads of the flat-six (EZ36). Remove the retaining bolt, swap the sensor, lightly oil the new O-ring, and refit. Torque should follow the Subaru service spec for that engine. Clear codes with a scan tool and verify live data and timing advance. No special relearn is usually required, but a short road test helps the ECU settle trims.

A competent home mechanic can often handle the job, but if there’s any doubt about wiring integrity, timing correlation, or recurring codes, a workshop with a scope and the Subaru service info will save time.

FAQs

Where is the camshaft sensor on a 2016 Subaru Outback?
On the 2.5i FB25, there’s a sensor mounted on each cylinder head near the front, just behind the timing chain cover and under the plastic engine cover. On the 3.6R EZ36, the sensors are also on the cylinder heads. They’re held in by a small bolt and sealed by an O-ring, with a two-pin electrical connector.

Access is straightforward with basic hand tools once the engine cover is off. Space can be tighter on the six, so patience helps.

Is it safe to drive with a faulty camshaft sensor?
It may still run, but starting can be hit-and-miss, and it might stall or run in a reduced-power strategy. That’s not ideal for daily use or long trips.

If the light’s on and the car is driving poorly, it’s best to avoid extended driving and get it checked. A quick scan for P0340/P0341 (and related codes) will confirm if the cam sensor circuit is the culprit.

How often should it be replaced and what does it cost?
There’s no interval—replace only if faulty. Quality sensors typically last many years. In Australia or New Zealand, parts generally run about $80–$200, with 0.5–1.0 hours labour typical depending on engine and access.

Prices vary by brand and workshop rates, so a proper diagnosis first is money well spent.
