Parts for your 2014 Ford Fiesta-Crank angle sensor

2014 Ford Fiesta crank angle sensor — what it is, where it fits, and when to replace it

Yes, the 2014 Ford Fiesta uses a crank angle sensor (more commonly called a crankshaft position or CKP sensor). Technical references including the Ford 2014 Fiesta Workshop Manual (Electronic Engine Controls, 303‑14), the Haynes Fiesta 2008–2017 manual, and Autodata list a CKP sensor across the 1.0 EcoBoost, 1.5/1.6 Duratec petrol, and 1.6 TDCi diesel engines. It’s an essential input for the Fiesta’s PCM (engine computer), so it’s absolutely relevant on this model year.

The CKP sensor reads a toothed wheel on the crank to report exact crank angle and speed. The PCM uses that signal to time spark and fuel injection, sync with the cam sensor for variable valve timing, and monitor misfires. If the signal is missing or flaky, the Fiesta can be hard to start, run rough, stall when hot, or not start at all.

While it’s not a scheduled service item, it’s smart to give it a once‑over during major services. Under the bonnet, check the sensor connector and harness routing for oil contamination, heat damage, or chafing. Keep an eye out for engine oil leaks that can wick into the plug, and don’t ignore metal swarf around the sensor nose if you’re doing other work nearby.

• Common symptoms of CKP issues: long crank/no start, intermittent stalling, erratic tacho during cranking, poor fuel economy, and fault codes such as P0335–P0339 or P0315.
• Basic replacement tips: disconnect the battery negative, unplug the sensor, remove its retaining bolt, swap the O‑ring if supplied, and refit. Route the loom exactly as per factory clips to avoid heat and rubbing. Tighten to manufacturer spec.
• After replacement: clear any codes and, if your scan tool supports it, run a crankshaft variation “relearn”. Many Fiestas will self‑learn after a few drive cycles, but a manual relearn helps lock it in.

Location varies slightly by engine. On many 1.0 EcoBoosts it’s mounted low on the block near the crank, on the 1.6 Duratec it’s typically by the bellhousing, diesels often sit near the front pulley. Access ranges from easy to a bit fiddly, so expect roughly 0.4–1.0 hour labour depending on engine and tooling. Using a quality OEM‑equivalent sensor avoids repeat faults and odd idle behaviour. If in doubt, a quick check with a scan tool for clean RPM during cranking and a tidy harness inspection will save a lot of head‑scratching.

FAQs

Does a 2014 Ford Fiesta have a crank angle sensor?
It does. Ford’s service information, Haynes, and Autodata all show a crankshaft position (crank angle) sensor fitted across the 2014 Fiesta engine range. Without it, the PCM can’t time spark or fuel, so the engine won’t run properly.

Where is the crank angle sensor on a 2014 Fiesta?
It depends on the engine. The 1.0 EcoBoost usually has it low on the block near the crank, the 1.6 Duratec often places it at the transmission bellhousing, the diesel sits near the crank pulley. A torch and mirror help if access is tight.

Do I need to program anything after replacing the sensor?
It’s good practice to clear codes and perform a crankshaft variation relearn with a capable scan tool. Many Fiestas will adapt on their own after a few drive cycles, but a relearn helps ensure crisp starting and smooth idle straight away.
