Parts for your 2007 Subaru Outback-Crank angle sensor

2007 Subaru Outback crank-angle-sensor (crankshaft position sensor)

The 2007 Subaru Outback does use a crank-angle-sensor (commonly called the crankshaft position sensor or CKP). This is documented in the Subaru Factory Service Manual for 2007 Legacy/Outback (engine diagnostics sections for DTC P0335/P0336), in Subaru’s Technical Information System wiring diagrams, and in OEM parts catalogues listing a dedicated crankshaft position sensor for both the 2.5-litre EJ253 and 3.0-litre EZ30 engines. It’s a core input for the ECU, not an optional extra.

On this Outback, the crank-angle-sensor monitors the crankshaft’s exact position and speed, feeding a precise timing signal to the ECU. That signal is used to trigger spark and fuel injection, manage variable valve timing where fitted, and keep the engine running smoothly from cold starts to highway cruising. Lose that signal and the car can be hard to start, stumble, or stop altogether.

Day to day, it’s a low-maintenance part, but it lives under the bonnet in heat and vibration. As part of regular servicing, it’s smart to inspect the harness and connector for brittle insulation, oil contamination, or green/white corrosion. A quick wipe of dust and grit around the sensor boss helps prevent debris getting onto the magnetic tip during any future removal. There’s no scheduled replacement interval, it’s a replace-when-faulty item.

• Common symptoms of a failing CKP: intermittent no-start, sudden stalling at idle, misfires under load, erratic tacho, poor fuel economy, and ECU fault codes like P0335/P0336.
• Typical causes: internal sensor failure from heat cycling, wiring fatigue near the timing cover, oil leaks softening the connector seal, or metal filings sticking to the sensor tip.

Replacement is straightforward for a competent DIYer with basic tools. Disconnect the battery, unplug the sensor, remove the single hold-down bolt, and withdraw the sensor carefully to avoid nicking the O-ring or the timing cover. Lightly oil a fresh O-ring on the new unit, seat it squarely, and tighten the bolt to the specification in the Subaru workshop manual. Clear codes and confirm a clean crank signal with a scan tool. If the loom looks tired, repair or replace the pigtail at the same time—poor wiring will send them round the bend chasing ghost faults. For workshop servicing, a quick scope check of the crank and cam signals together is a tidy way to verify the health of the timing reference on these engines.

Where is the crank-angle-sensor on a 2007 Subaru Outback?

It’s mounted at the front of the engine, reading a toothed reluctor on the crank. On the EJ25, access is from the front of the block near the timing belt area. Technicians usually reach it with the intake snorkel out of the way and, if needed, the front cover loosened for clearance.

On the 3.0R H6, it’s also positioned to read the crank’s tone wheel at the front cover. Either way, expect it near the crank pulley/timing cover, with a short two-wire harness plugging into the engine loom.

Can a dodgy crank-angle-sensor be cleaned, or does it need replacing?

If the tip just has light debris or fine metal fuzz, a gentle clean can restore the signal. However, once a CKP develops internal faults from heat or vibration, cleaning won’t fix it. Replacing the sensor and ensuring the connector and earths are sound is the reliable repair.

What codes point to a bad crank-angle-sensor on this model?

Typical engine codes are P0335 (Crankshaft Position Sensor Circuit) and P0336 (Crankshaft Position Sensor Range/Performance). Some owners also see random misfire codes if the signal drops out intermittently. Always check wiring and connector condition before condemning the sensor.
