Parts for your 2013 Ford Mondeo-Crank angle sensor

2013 Ford Mondeo crank-angle sensor (CKP): what it is and how it’s looked after

It’s relevant and it’s fitted. The 2013 Ford Mondeo uses a crank-angle sensor, more commonly called the crankshaft position (CKP) sensor. Modern Ford engine management won’t run without one. This is documented in Ford’s Workshop Manual (WSM, Section 303 – Engine, Electronic Engine Controls/CKP sensor), independent data such as Autodata engine management overviews for 2007–2014 Mondeo, and the Haynes Mondeo 2007–2014 service manual, all of which list testing and replacement procedures for the CKP on petrol (EcoBoost/Duratec) and Duratorq diesel variants.

On this Mondeo, the CKP’s job is to tell the ECU exactly where the crankshaft is, so fuel and spark (or injection timing on diesels) happen bang on time. It reads a toothed wheel on the crank and sends a clean timing signal, lose that signal and the engine may crank but not start, stall at idle, or run rough. Common fault codes include P0335–P0339.

It’s not a scheduled service item, but it does deserve a once‑over during regular servicing. Good practice is to check the sensor connector and loom for chafing, oil contamination from rocker cover or rear main leaks, and ensure the mounting area is clean. A light film of dust is normal, heavy metal fuzz or damage isn’t. Keeping the engine bay tidy and leaks sorted helps the CKP live a long life, particularly in Aussie and Kiwi conditions with plenty of heat and dust.

Replacement is straightforward on most 2013 Mondeo engines: usually one retaining bolt and an indexed fit into the block or bellhousing area (location varies slightly by engine, commonly down by the gearbox bellhousing or near the crank pulley). Expect roughly 0.5–1.0 hour for access and swap on a hoist. Use an OEM‑quality sensor, lightly oil the O‑ring if fitted, and torque to spec from the service data. After installation, clear any codes and check live data for a stable RPM signal. Most Mondeo variants won’t need coding, but some workshops perform a crank relearn with a scan tool to speed up adaptation. If the problem was caused by wiring, repair the loom and secure it away from hot exhaust components. As always, battery off under the bonnet before unplugging engine sensors keeps things safe.

• Typical symptoms when failing: long crank/no start, random stalling, misfire at low RPM, P0335–P0339 stored.
• Preventative tip: fix oil leaks early and keep connectors clean and tight.

Popular questions

Where is the crank-angle sensor on a 2013 Ford Mondeo?
Most engines in this model have the CKP low on the engine, reading the flywheel or a reluctor on the crank. That’s typically at the gearbox bellhousing on the rear of the block, or down by the crank pulley on some petrol variants. Access can be from underneath with the splash shield off.

What are the common signs the CKP has failed on a 2013 Mondeo?
Hard starting or a complete no‑start after a hot soak, intermittent stalling at idle, erratic tachometer behaviour, and stored codes P0335–P0339 are the usual tells. If it starts fine cold but dies warm, the sensor or its wiring may be heat‑soaked. Always check the connector and harness before condemning the sensor.

Does a new CKP need programming on this model?
Generally, no coding is required. Fit the sensor, clear fault codes, and let the ECU relearn during a short drive and steady idle. Some workshops run a crank position relearn with a scan tool to speed things up, especially if the battery has been flat or multiple sensors have been disturbed.
