Parts for your 2009 Mitsubishi Outlander-Crank angle sensor

2009 Mitsubishi Outlander crank-angle sensor: what it is, where it lives, and when to sort it

Yes, the 2009 Mitsubishi Outlander is fitted with a crank‑angle sensor (commonly called the crankshaft position sensor, or CKP). Technical references that document this include the Mitsubishi Outlander (CW/ZE–ZH, 2007–2012) Factory Workshop Manual, Group 13A – Multiport Fuel Injection (MFI), which details the CKP sensor operation and diagnostics (including DTC P0335), and the Mitsubishi ASA electronic parts catalogue, which lists a crankshaft position sensor for both the 2.4L 4B12 and 3.0L 6B31 engines used in 2009 models.

On the 2009 Outlander, the crank‑angle sensor is the engine’s timekeeper. It reads a toothed wheel on the crank to tell the ECU exactly where the pistons are and how fast they’re moving. The ECU then times the fuel injection and spark, manages idle quality, and even supports misfire monitoring. Paired with the cam sensor, it helps the MIVEC system and ignition stay bang on, so the Outlander starts crisply, runs smoothly, and sips fuel the way it should.

When the crank‑angle sensor gets lazy or fails, the symptoms can be a real nuisance: hard starting or no start, random stalling (often when hot), a rough idle, sluggish performance, and a glowing check‑engine light with codes like P0335–P0339. Because the ECU relies on a clean signal, even wiring issues—like a chafed loom or an oily, loose connector—can mimic a dud sensor.

It’s not a scheduled service item, but it’s smart to give it a once‑over during major services (say each 100,000 km). On the 2.4L 4B12, the sensor sits low at the front of the engine near the crank pulley/oil pump area and is usually accessed from underneath. On the 3.0L 6B31 V6, it’s mounted near the transmission bellhousing. Keep the area clean, check the plug for oil ingress or brittle insulation, and make sure the harness is clipped away from heat and moving parts.

If replacement’s on the cards, go for an OEM‑quality sensor, fit a fresh O‑ring if applicable, lightly oil the seal, and torque the retaining bolt to the spec in the factory manual. Disconnect the battery before you start, route the lead exactly as per factory, and clear any stored fault codes afterwards. Most Outlanders don’t need special programming for a CKP swap—the ECU will relearn on its own after a short drive cycle—but verifying live data with a scan tool is a tidy way to confirm the fix.

• Watch for intermittent hot stalls and a P0335 code.
• Inspect connectors for oil and corrosion.
• Don’t ignore harness rub points near the lower front of the engine.

Where is the crank‑angle sensor on a 2009 Outlander?

On the 2.4L 4B12, it’s mounted low at the front of the engine near the crank pulley/oil pump housing, typically accessed from under the vehicle. On the 3.0L 6B31 V6, it’s positioned near the transmission bellhousing. Access varies a bit with under‑trays and whether the vehicle is 2WD or AWD.

What are the common signs it’s failing?

Hard starting or a no‑start when hot, random stalling, rough idle, and a check‑engine light are the usual giveaways. Scan tools often show codes like P0335 (CKP circuit). Because wiring faults can copy the same symptoms, always check the loom and connector first.

Does it need programming after replacement?

Generally, no. The Outlander’s ECU will relearn the signal automatically after a short drive. Clear fault codes, confirm the engine starts cleanly, and verify live RPM on a scan tool. If codes return, recheck connector fitment, harness routing, and sensor seating.
