Parts for your 2013 Subaru Forester-Camshaft sensor

2013 Subaru Forester Camshaft Sensor

Yes, the 2013 Subaru Forester uses a camshaft position sensor. Subaru’s 2013 Forester (SH) factory service manual details diagnostics for DTCs like P0340 and P0345 relating to the camshaft position sensor, and the Subaru parts catalogue lists camshaft position sensors for both the 2.5i (EJ253) and turbo XT (EJ255) variants. Trade databases such as Subaru STIS and workshop systems like AllDataDIY and Mitchell1 also document testing and replacement procedures for this sensor on the 2013 model.

On this Forester, the camshaft sensor tells the engine control module exactly where the camshaft is in its rotation. That lets the ECU line up fuel injection and spark timing bang-on, trim cold starts, and manage variable valve timing on turbo XT models. In plain speak, it helps the Forester start cleanly, idle smoothly, and use less petrol. The non-turbo 2.5i typically runs a single cam sensor, while the XT turbo uses two (one per bank) to keep the AVCS timing in check.

It’s not a scheduled replacement item, but it’s smart to give it a once-over during regular servicing—say every 10,000–15,000 kilometres when the bonnet’s up anyway. Look for oil seepage onto the sensor or plug, brittle wiring, and green crusties in the connector. Heat and age are the usual villains, a failing sensor can cause a long crank, intermittent stalling, rough running, or a lit check engine lamp with those P0340/P0345 codes.

• Symptoms to watch for: hard starting, random misfires, sluggish performance, poor fuel economy, and a check engine light.
• Quick checks: inspect the harness for rub-through near the timing cover, ensure the connector is snug, and keep the area free of oil leaks.

If replacement is on the cards, it’s a straightforward driveway job for a handy owner: disconnect the battery, remove the engine cover, unplug the sensor, undo the single retaining bolt, and pull the sensor straight out. Swap the O-ring (lightly oil it), seat the new sensor squarely, and snug the bolt to the manufacturer’s spec—don’t overdo it on the spanner. Reconnect, clear codes, and take a short test drive to confirm happy starts and smooth behaviour. For best results, stick with an OE or high-quality aftermarket sensor that matches the Forester’s engine code.

Keeping the engine oil clean and at the right level also helps, particularly on AVCS-equipped XTs, because stable oil control makes cam timing—and the sensor signal—more consistent.

Popular questions about the 2013 Subaru Forester camshaft sensor

How many camshaft sensors does a 2013 Forester have?
Most 2.5i non‑turbo models use one camshaft position sensor. The XT turbo typically uses two, one per cylinder bank for AVCS control. If unsure, check the build plate/engine code or peek under the engine cover for the sensor count and connectors.

Is it safe to drive with a failing camshaft sensor?
It may run, but it can be hard to start, stumble, or drop into limp mode. That’s risky for overtaking and could leave the driver stranded. Best bet is to scan for codes, address wiring or oil leaks, and replace the sensor sooner rather than later.

Can the camshaft sensor be cleaned instead of replaced?
If the issue is light oil contamination on the body or connector, a careful clean can help. But if the internal electronics are failing or the signal is erratic, cleaning won’t fix it. In that case, fit a quality replacement and inspect the harness.
