Parts for your 2019 Ford Mondeo-Crank angle sensor

2019 Ford Mondeo crank angle sensor (crankshaft position sensor)

Based on technical sources including the Ford Workshop Manual (2019 Mondeo/Fusion, Section 303-14: Electronic Engine Controls — Crankshaft Position Sensor), Ford Electronic Parts Catalogue listings for the 1.5L/2.0L EcoBoost petrol and 2.0L EcoBlue diesel engines, and independent data providers such as Autodata and Haynes, the 2019 Ford Mondeo is fitted with a crank angle sensor (commonly called the crankshaft position or CKP sensor). It’s a core engine management component on all these engines.

The crank angle sensor on a 2019 Mondeo tells the powertrain control module exactly where the crankshaft is and how fast it’s spinning. That precise timing signal lets the ECU fire injectors and spark at the right moment, coordinate with the cam sensor for variable valve timing, and monitor misfires. If the CKP signal drops out, the engine may refuse to start, stall, or run poorly. It’s one of those small parts that quietly keeps everything under the bonnet working spot on.

While it isn’t a scheduled service item, it deserves a look during major services or after engine/gearbox work. Check the wiring loom for chafing, brittle insulation, or oil contamination, and make sure the connector is clean and latched. A light wipe of the sensor tip to remove metal fuzz (on magnetic types) is fine, avoid harsh solvents.

Common signs it’s on the way out include extended cranking or no-start when hot, random stalling, erratic tacho, rough idle, poor fuel economy, and engine light with codes like P0335/P0336. A quick clue with a scan tool is 0 rpm shown while cranking — that points straight at the CKP circuit. Pros may also scope the waveform or verify 5 V reference, signal, and ground integrity.

Replacement is straightforward with basic tools. Disconnect the battery negative, safely raise the car, and locate the sensor — typically at the gearbox bellhousing or the front of the block near the crank pulley, depending on engine. Unplug the connector, remove the retaining bolt, and ease the sensor out. Lightly oil the new O-ring, seat the sensor fully, and tighten to the manufacturer’s spec. Route the loom away from heat and moving parts. Clear any fault codes and, if required by the ECU strategy, perform a crank position relearn with a capable scan tool. A short road test seals the deal.

Handy tips:

• Don’t pry on the reluctor ring or flywheel teeth.
• Keep the sensor face clean, avoid metal shavings.
• If issues persist, inspect the cam sensor and timing hardware too — they work as a pair.

Popular questions about the 2019 Ford Mondeo crank angle sensor

Where is the crank angle sensor located on a 2019 Mondeo?

Depending on engine, it’s usually mounted at the gearbox bellhousing reading the flywheel/flexplate teeth, or at the front of the engine near the crank pulley reading a reluctor wheel. Access is often easier from underneath with the splash shield off.

If you’re unsure which engine you’ve got, check the build plate or engine cover, the mounting spot varies slightly between the EcoBoost petrol and EcoBlue diesel.

Do I need to program the car after replacing the crank sensor?

Many Mondeos will relearn automatically after a few clean starts and a short drive, provided you’ve cleared fault codes. Some variants may require a crank position relearn using a professional scan tool. If the idle is rough or misfire counters climb post-repair, perform the relearn to tidy it up.

What’s the ballpark replacement time?

With tools at the ready, around 0.7–1.2 hours is typical, depending on engine layout and undertray removal. Corrosion, tight access, or seized fasteners can add time. Always allow extra if you’re working on stands in the driveway.
