Parts for your 2019 Ford Mondeo-Camshaft sensor

2019 Ford Mondeo camshaft sensor – purpose, servicing and replacement

Per Ford Workshop Manual (Mondeo/Fusion CD391 platform), Ford ETIS/Service Information, Autodata (2024), and the Haynes Mondeo Mk5 guide, the 2019 Ford Mondeo is fitted with camshaft position sensor(s). All common 2019 engines — 1.5L and 2.0L EcoBoost petrol and 2.0L EcoBlue diesel — use a camshaft sensor to manage sequential injection, ignition timing, and variable valve timing. Some variants have two sensors (intake and exhaust).

The camshaft sensor (often called the CMP) tracks the exact position and speed of the camshaft and works with the crankshaft sensor to keep the engine in sync. That accurate timing means clean starts, smooth idle, crisp throttle response and the right cam phasing for power and fuel economy. It’s a small Hall-effect sensor with a big job, and modern Mondeos simply won’t run properly without it.

While the CMP isn’t a scheduled service item, it pays to keep an eye on it during routine servicing. Clean, correct-spec engine oil helps the cam phasers operate as designed, which indirectly keeps the sensor readings stable. A quick look under the bonnet for wiring chafe, oil intrusion at the connector, or a loose mounting bolt can prevent dramas later.

• Common fault signs: long crank or no-start, rough idle, misfire under load, drop in fuel economy, limp-home mode, or the MIL on with codes like P0340–P0344 or cam/crank correlation faults (P0016–P0019).
• Location: typically at the front or top of the cylinder head by the timing cover, some engines use one on the intake side and another on the exhaust side.

Replacement is straightforward for a competent home mechanic, but many owners prefer a technician to confirm diagnosis first, as wiring or connector issues can mimic a failed sensor.

1. Confirm with a scan tool and live data, inspect wiring and connector for oil, corrosion or chafe.
2. Remove the engine cover, disconnect the battery negative, then unplug the sensor.
3. Undo the retaining bolt, ease the sensor out, and check the O-ring.
4. Lightly oil the new O-ring, install the new OEM-quality sensor, and tighten the bolt to the workshop-manual spec.
5. Clear codes and road test, most ECUs relearn automatically, though some tools offer a cam/crank relearn function.

A quality replacement sensor and a tidy harness usually restore normal running straight away. If faults persist, a deeper check of timing components, oil condition, and cam phasers is worthwhile.

Where is the camshaft sensor on a 2019 Ford Mondeo?

On most 2.0L EcoBlue and EcoBoost engines it sits near the front of the cylinder head by the timing cover. Some versions have one sensor on the intake cam and another on the exhaust cam. Access is typically under the plastic engine cover.

Is a camshaft sensor failure common on these cars?

It’s not especially common, but age, heat, oil ingress and wiring chafe can cause issues. Many “sensor” faults turn out to be a damaged connector or harness, so diagnosis before parts swapping is smart.

Can the car be driven with a faulty camshaft sensor?

If it starts at all, it may run roughly or enter limp mode. Driving like that risks poor fuel economy and further issues. It’s best to have the fault checked and repaired promptly.
