Parts for your 2014 Ford Focus-Crank angle sensor

2014 Ford Focus crank-angle sensor (crankshaft position sensor)

Based on technical sources, the 2014 Ford Focus is fitted with a crank-angle sensor, commonly listed by Ford as the crankshaft position (CKP) sensor. The Ford factory workshop manual for the LW/LZ Focus (2012–2014) includes the CKP in engine management and diagnostics, with DTCs P0335–P0339. Reputable service data and catalogues (e.g., Motorcraft service information, Autodata/Haynes, and OE supplier listings) also show a CKP sensor across the 1.6L, 1.0L EcoBoost, 2.0L GDI petrol, and diesel variants.

On the 2014 Focus, the crank-angle sensor’s job is to read a toothed wheel on the crankshaft and feed the engine computer exact crank speed and position. That live signal lets the PCM fire the injectors and spark at the right time, keep idle stable, sync with the cam sensor, manage variable valve timing, and flag misfires. If the signal drops out, the Focus may crank for ages, stall, run roughly, or refuse to start altogether. It’s one of those quiet heroes that makes modern engines feel smooth and responsive.

This sensor isn’t a scheduled service item, but it’s smart to keep an eye on things during routine servicing. A quick visual once-over under the bonnet or from beneath the car (splash shield off) can catch chafed wiring, oil-soaked connectors, or road grime built up around the sensor. Electrical gremlins are more common than the sensor itself failing, so clean, tight connectors matter.

Replacement is generally straightforward for a competent tech. Battery negative off, unplug the sensor, remove the single retaining bolt, and gently twist the sensor free (there’s an O-ring). Fit the new unit with a lightly oiled O-ring, seat it fully, and torque the bolt to the workshop spec. Route the loom away from hot spots and moving parts. After refitting, clear any codes and check live data, some scan tools offer a crank relearn/neutral profile correction procedure, which can help the PCM fine-tune misfire monitoring. Most Focus engines use a non-adjustable, fixed-gap sensor—no shims or guesswork required.

Typical symptoms of a crook CKP include intermittent stalling when hot, a dead tacho during cranking, P0335–P0339 codes, or a no-start. Before blaming the sensor, it pays to rule out a weak battery, loose grounds, or fuel delivery issues. When a new sensor is needed, OE-quality parts tend to behave best, and given how critical timing is, it’s worth doing once and doing right. If the car has gone a fair few kilometres and shows those tell-tale signs, prompt attention can save a roadside tow.

Does a 2014 Ford Focus have a crank-angle sensor, and where is it?

Yes. All common 2014 Focus engines use a CKP. Location varies by engine: on many 2.0L GDI models it’s mounted near the rear of the block by the bellhousing, on some EcoBoost variants it’s down near the crank pulley. Either way, it reads a toothed reluctor on the crank.

What are the signs a CKP is failing on this model?

Hard starting, stalling when hot, an erratic or dead tacho during crank, rough running, and the check engine lamp are typical. Scan tools often show P0335–P0339. Because wiring damage can mimic a bad sensor, the connector and harness should be checked first.

Is it safe to keep driving with a dodgy CKP, and how long does replacement take?

It can quit without much warning, so it’s risky. If the engine starts cutting out, it’s better to get it sorted or arrange a tow. Replacement time is usually under a couple of hours with basic access, using a quality sensor and following the workshop procedure keeps things drama-free.
