2009 Mitsubishi Outlander Camshaft Sensor
Based on Mitsubishi’s own technical literature, the 2009 Outlander does use a camshaft position sensor (CMP). The Mitsubishi Outlander (CW-series, model year 2009) service manual—Engine and Engine Electrical sections—and the Mitsubishi ASA electronic parts catalogue list camshaft position sensor(s) for the 4B11 2.0L, 4B12 2.4L, 6B31 3.0L V6, and the diesel variants. Diagrams in the manual show a CMP on the cylinder head, with dual sensors on the DOHC 4B1 engines (one on each cam) to support MIVEC (variable valve timing) and sequential injection. So yes, it’s fitted and it’s important.
On the 2009 Outlander, the camshaft sensor lets the ECU know exactly where the cam(s) are in their rotation. That timing signal is crucial for crisp starts, smooth idle, proper VVT control, and accurate fuel and spark events. When a CMP goes out of whack, the car can crank longer, hesitate, surge, or throw fault codes like P0340/P0341. The check engine light is the usual giveaway, and the ECU may drop into a safe mode that dulls performance and economy.
While the CMP isn’t a routine replacement item, it’s worth a quick look during servicing. A visual once-over of the sensor body and connector, plus a check that the loom isn’t chafing on the rocker cover, can save headaches down the track. Oil weep at the O-ring or a green/white tinge on the pins (corrosion) are cues to act. On the 4B11/4B12, remember there are two sensors—intake and exhaust—though they don’t have to be replaced in pairs unless diagnostics suggest it.
If replacement’s on the cards, it’s a straightforward DIY for most owners:
- Disconnect the battery, let the engine cool.
- Locate the sensor on the cylinder head (front for intake, rear for exhaust on 4B1 DOHC, V6 and diesel may differ slightly).
- Unplug the connector, remove the single retaining bolt, and twist-pull the sensor out.
- Lightly oil the new O-ring, seat the new sensor, and tighten the bolt to the specified torque (around 8–10 N·m, check the service manual for your engine).
- Clear codes and confirm no new faults with a scan tool.
Good quality OEM-equivalent sensors tend to play nicest with Mitsubishi’s MIVEC control. If intermittent faults persist, consider checking the crank sensor signal and ECU grounds as well—these work as a team.
FAQs
Where is the camshaft sensor on a 2009 Outlander?
On 4B11/4B12 petrol engines, there are two—one on the intake side and one on the exhaust side of the cylinder head. The 3.0L V6 and diesel have their CMP mounted on the cylinder head near the cam gear end. Access is typically from the top of the engine once covers are out of the way.
What are the symptoms of a failing camshaft sensor?
Common signs include hard starting, rough idle, loss of power, poor fuel economy, and the check engine light. You might see codes like P0340–P0344. If left too long, the ECU may limit performance to protect the engine.
Do all 2009 Outlanders have one or two camshaft sensors?
Most 4B11/4B12 DOHC petrol models use two sensors (intake and exhaust). The 3.0L V6 and the diesel typically use a single CMP. The Mitsubishi service manual and the ASA parts catalogue for your VIN will confirm the exact setup.
