Parts for your 2012 Mitsubishi Outlander-Crank angle sensor

2012 Mitsubishi Outlander crank-angle sensor: what it does, why it matters, and how to look after it

Based on Mitsubishi technical documentation, the 2012 Mitsubishi Outlander is fitted with a crank-angle sensor (more commonly listed as the crankshaft position sensor, CKP). This is confirmed in the Mitsubishi Outlander 2010–2012 Workshop Manual (Group 11 – Engine, sections covering the 4B11/4B12, 6B31 and 4N14 engines) and the Mitsubishi ASA parts catalogue, which list a CKP for the petrol and diesel variants of this model year. Related OBD-II diagnostics for this vehicle family include CKP fault codes such as P0335–P0339.

On a 2012 Outlander, the crank-angle sensor is the ECU’s timekeeper. It reads a toothed wheel on the crankshaft to report exact crank position and engine speed, letting the ECU fire the spark and inject the fuel bang on time. It also works with the cam sensor to confirm engine phase, so cold starts, smooth idle and decent fuel economy all rely on a clean, accurate signal from this little unit.

It’s not a routine service item, but it does pay to give it some love when you’re under the bonnet. During scheduled servicing, a tech will usually eyeball the connector and harness for heat or oil damage, make sure the wiring is clipped away from the belts, and check for tell-tale fault codes. If the engine has had an oil leak or timing work, it’s smart to clean the area around the sensor to keep grime off the magnetic tip.

Owners typically notice trouble as hard starting or a no-start, random stalling at lights, rough idle, misfires, or the check engine light. Common codes include P0335 (crank sensor circuit) and related range/performance or intermittent codes. If those show up, replacing the sensor is generally the fix.

Replacement is straightforward for a trained tech: disconnect the battery, locate the sensor (position varies by engine), unplug, remove the retaining bolt, and swap in a new sensor with a fresh O-ring. The sensor is non-adjustable on these engines, so it’s a simple in/out job—just torque to spec from the workshop manual, route the harness correctly, clear codes and perform any idle relearn if needed. Using a quality OEM-equivalent part is worth it, cheap units can cause intermittent gremlins.

Because location and access differ between the 2.4 petrol, 3.0 V6, and the diesel, the labour time can vary. A quick test with a scan tool and an oscilloscope trace is the proper way to confirm the diagnosis before reaching for the spanners.

• Typical symptoms: hard/no start, random stall, rough idle, poor fuel, CEL on
• Typical causes: sensor failure, damaged wiring, oil contamination, cracked reluctor
• Service tip: inspect connectors and harness during routine services and after timing work

Popular questions

Where is the crank-angle sensor on a 2012 Outlander?
Location depends on the engine. On most 4B11/4B12 2.0/2.4 petrols it’s mounted near the front timing cover reading the crank trigger wheel. On the 3.0L V6 (6B31) it’s commonly positioned near the transmission bellhousing. On the 2.2 diesel (4N14) it’s typically on the block reading the flywheel/reluctor. Access ranges from easy to fiddly, so workshop access from underneath may be required.

What fault codes point to a bad crank-angle sensor?
The usual suspects are P0335 (crankshaft position sensor circuit) and related codes like P0336–P0339 for performance or intermittent signals. Symptoms can include cranking with no fire, stalling, rough running, and the check engine light. Always check wiring and connectors before condemning the sensor.

Is it safe to drive with a failing crank-angle sensor?
It’s risky. Some Outlanders may run poorly or stall without warning, and others won’t restart once they’ve cooled and been heat-soaked again. If the car is showing symptoms or logging CKP codes, it’s best to arrange diagnosis and repair promptly rather than push your luck on the motorway.
