Parts for your 2016 Mitsubishi Lancer-Crank angle sensor

2016 Mitsubishi Lancer crank angle sensor: purpose, servicing and replacement

Technical documentation confirms the 2016 Mitsubishi Lancer is fitted with a crank angle sensor (often called a crankshaft position sensor, or CKP). Mitsubishi’s Lancer Service Manual for the CY/CZ platform (2007–2017) details the CKP in the Engine Electrical section, and the Mitsubishi ASA electronic parts catalogue lists a crankshaft position sensor for 4B10/4B11/4B12 engines used in 2016 models. Independent manuals (e.g., Haynes Lancer 2007–2017) and trade databases such as Autodata/Mitchell also show diagnostics and replacement procedures for the CKP on this vehicle range.

This little sensor does a big job. Mounted to the engine block and reading a toothed wheel on the crankshaft, the Lancer’s crank-angle-sensor tells the ECU exactly where the crank is and how fast it’s spinning. The ECU pairs that with the cam sensor to time spark and fuel with precision, handle cold starts, detect misfires, and keep idle nice and steady. If it drops out, the car may crank but not start, or run rough and stall.

It’s not a routine replacement item, but it’s smart to give it some love during regular servicing:

• Visual checks: look for oil contamination, heat damage, or chafed wiring at the sensor plug and loom routing.
• Connector care: ensure terminals are clean and tight, a light dab of dielectric grease helps keep moisture away.
• Fault clues: watch for hard starting, sudden tach drop-outs, intermittent stalling, and codes like P0335–P0339.

When replacement is needed, it’s a straightforward job for most home mechanics with basic tools. Disconnect the battery, unplug the sensor, remove the retaining bolt, and ease the sensor out. A new O-ring should be lightly oiled before installation. Refit, torque to the manufacturer spec, reconnect, clear any fault codes, and road test. An idle relearn after battery disconnect is often recommended, full programming is typically not required on the 4B1-series engines.

Choosing the right part matters. Stick with genuine or high-quality OE-equivalent sensors and match by VIN/engine code to avoid fitment hassles. Because the sensor reads a magnetic target, avoid metal debris around the mounting area, and don’t pry on the tip.

Looking after the basics—good battery condition, clean earths, and tidy wiring—goes a long way to keeping the Lancer’s crank-angle-sensor happy and the engine running sweet across Aussie and Kiwi roads.

• Where is the crank-angle-sensor on a 2016 Lancer?
  It’s mounted to the engine block and reads a toothed wheel on the crank. On most 2.0L/2.4L Lancers it’s low on the block near the crank pulley or bellhousing area. Access is usually from underneath with the splash shield removed.
• What are common symptoms or fault codes?
  Hard starting, intermittent stalling, rough idle, misfire feel, and the tacho dropping to zero are common. Typical fault codes include P0335–P0339 for crankshaft position sensor circuit/performance.
• Does a new sensor need programming?
  Generally no. The ECU on the 4B1 engines self-learns. After fitting, clear codes and perform an idle relearn if the battery was disconnected.
