2014 Mitsubishi ASX crank-angle-sensor (crankshaft position sensor): purpose, servicing and replacement

Based on technical references, the 2014 Mitsubishi ASX is fitted with a crank-angle-sensor, more commonly called a crankshaft position (CKP) sensor. This is documented in Mitsubishi’s ASX/Outlander Sport workshop/service manual (2010–2015) under Engine/ECM diagnostics, which includes CKP-related fault codes (P0335–P0339) and test procedures, it’s also listed in the Mitsubishi ASA electronic parts catalogue for the 4B11/4B12 and 4A92 engines. These sources make it clear the ASX relies on a CKP sensor for ignition and fuel timing.

• Mitsubishi ASA/parts catalogue: CKP sensor listed for 4B11/4B12/4A92 engines.

On the 2014 Mitsubishi ASX, the crank-angle-sensor is a critical piece of the engine management puzzle. It monitors crankshaft position and speed, letting the ECU know exactly when to fire the spark and deliver fuel. Without a clean signal, the ASX can be hard to start, run rough, or stall. That’s why any hint of P0335-style fault codes, misfiring, or sudden cut-outs under the bonnet should put this sensor on the checklist.

There’s no set replacement interval for the crank-angle-sensor, it’s a replace-when-faulty item. As part of regular servicing, it pays to:

• Scan for stored or pending CKP codes and check live RPM signal during cranking.
• Inspect the CKP wiring and connector near the front cover or bellhousing for chafing, oil ingress, or corrosion.
• Keep the area around the sensor clean, ferrous debris on the sensor tip can distort the signal.

If replacement is needed on a 2014 ASX, it’s a straightforward job for a workshop and very doable for a confident home mechanic. Disconnect the battery, access the sensor (typically by the crank pulley or transmission bellhousing on these engines), unplug, remove the hold-down bolt, and swap the unit. The air gap is factory-set by the sensor design and mounting face, so there’s no adjustment, just make sure the mating surface is clean and the O-ring is seated. Avoid cheap no-name sensors, an OE or reputable aftermarket unit saves headaches with signal quality and hot-start issues.

After fitting, clear codes, check for an immediate crank RPM signal, and take the ASX for a run to confirm stable idle and smooth acceleration. If symptoms persist, inspect the trigger wheel and verify cam sensor correlation, as the ECU uses both to keep timing spot-on.

Popular questions about the 2014 Mitsubishi ASX crank-angle-sensor

Where is the crank-angle-sensor located on a 2014 ASX?

On most 2014 ASX models, the sensor sits at the front of the engine by the crank pulley or at the transmission bellhousing, reading a toothed wheel on the crank. Access varies slightly with engine and drivetrain, but it’s typically reached from underneath with the splash shield removed.

What are the common signs the ASX crank-angle-sensor is failing?

Hard starting, intermittent stalling, tachometer dropping to zero while cranking, rough running, and a check engine light with codes like P0335 are classic signs. If the ECU loses the CKP signal altogether, the engine won’t start.

Should the CKP sensor be replaced during routine servicing?

No, it’s not a scheduled item. It’s replaced on condition. During services, a quick scan for codes, a visual on the loom and connector, and ensuring there’s no oil contamination are enough. Replace only if there’s a confirmed signal fault or physical damage.
