Parts for your 2016 Ford Mondeo-Crank angle sensor

2016 Ford Mondeo crank-angle sensor (crankshaft position sensor)

Yes, the 2016 Ford Mondeo is fitted with a crank‑angle sensor (Ford calls it the Crankshaft Position Sensor, or CKP). Technical coverage in the Ford Workshop Manual for Mondeo 2014–2019 (Section 303—Engine, including 303‑14A/303‑04) describes CKP function, diagnostics and replacement. Industry references such as Autodata and Haynes list a CKP for the 1.5/2.0 EcoBoost petrol and 2.0 TDCi diesel engines, and Ford’s Microcat/ETIS parts catalogue carries the CKP under the 12A112 group for this model year.

The CKP is the engine’s timekeeper. It reads a toothed wheel on the crankshaft and tells the PCM exactly where each piston is and how fast the engine is spinning. That live crank angle data lets the PCM trigger spark and injection precisely, sync with the cam sensor for sequential fuel delivery, detect misfires, run the tachometer, and manage starting and stability control strategies. If the signal goes missing, the car can crank but not fire, stumble, or cut out unexpectedly. On the Mondeo, the EcoBoost petrols usually mount the sensor at the front cover near the crank pulley, while the 2.0 TDCi reads off the flywheel at the transmission bellhousing.

It’s not a scheduled replacement item, but it’s smart to give it some love during regular servicing. A quick visual check every 15–20,000 kilometres for oil contamination, damaged wiring looms, loose clips, or a connector full of dust or moisture can prevent dramas. If there are hard starts, random stalls, a dead tacho, or the MIL is on with codes like P0335–P0339, don’t just parts‑swap—scan it, scope it if possible, and inspect the reluctor teeth and sensor air gap. Heat soak and oil wicking in the harness are common culprits.

When replacement is needed, go with a quality OE‑equivalent sensor and a fresh O‑ring. Disconnect the battery, gain access (often via the wheel arch liner or lower undertray), unplug the connector, remove the retaining bolt, and draw the sensor straight out. Lightly lubricate the new O‑ring, seat the sensor squarely, and route the loom exactly as factory to avoid chafe. After installation, clear fault codes and carry out a crank position relearn with a capable scan tool (Ford IDS/FDRS or FORScan). A short road test with a few gentle accelerations helps the PCM confirm signal quality. It’s typically a short job for a workshop, and keeping the connector clean and the loom secure will help the CKP live a long, drama‑free life.

Popular questions about the 2016 Ford Mondeo crank-angle sensor

Where is the crank-angle sensor on a 2016 Ford Mondeo?
The 1.5L and 2.0L EcoBoost petrol engines usually place the sensor at the front of the engine, reading a toothed wheel behind the crank pulley. The 2.0L TDCi diesel typically mounts the sensor at the bellhousing, reading the flywheel. Access is commonly from the lower front or via the right wheel arch liner.

Do I need to program or relearn anything after replacing the CKP?
Often the PCM will adapt on its own, but it’s best practice to perform a crankshaft position relearn with a suitable scan tool, then clear any codes and road test. This helps ensure stable idle, accurate timing and clean restarts once warm.

What symptoms point to a failing crank-angle sensor?
Hard starting (hot or cold), intermittent stalling, a no‑start with good fuel pressure, rough idle, a dead or jumpy tachometer, and stored DTCs like P0335–P0339 are common signs. If these show up, check wiring and connectors before condemning the sensor.
