Parts for your 2011 Ford Mondeo-Camshaft sensor

2011 Ford Mondeo camshaft sensor — purpose, service and replacement

Based on technical sources including the Ford factory workshop manual (Mondeo 2007.5–2014, Engine Management 303-14), Ford parts catalogues (e.g., Microcat/ETIS listings for 2011 VIN ranges), and standard service information (Autodata/Haynes), the 2011 Ford Mondeo is equipped with a camshaft position (CMP) sensor on all common engines offered that year (petrol EcoBoost/Ti‑VCT and Duratorq TDCi diesel). On some variants there may be two CMP sensors—one for the intake cam and one for the exhaust cam.

On this Mondeo, the camshaft sensor tells the engine control module exactly where the cam(s) are in their rotation. That allows spot‑on sequential fuel injection, precise ignition timing on petrol engines, and proper operation of variable valve timing (VCT/Ti‑VCT). It also helps the ECU sync with the crank sensor during cranking, so cold starts are cleaner and quicker. On Duratorq TDCi diesels, accurate cam reference is critical for injection timing and smooth idle.

It’s not a scheduled replacement item, but it plays a big role in day‑to‑day drivability. When a CMP begins to fail, the car may log faults (common codes include P0340, P0341, P0344 and sometimes correlation codes like P0016), and owners might notice:

• Hard starting, extended cranking or intermittent no‑start
• Rough idle, misfire, hesitation or flat spots
• Poor fuel economy and a lack of punch
• Limp‑home mode, stalling at low speed, or the MIL/engine light on

During routine servicing, a quick once‑over under the bonnet helps. Check the CMP’s connector for loose pins, oil ingress, or brittle wiring near the rocker cover. Oil leaks from the cam cover can contaminate the plug, sorting leaks early protects the sensor. If the loom’s conduit is cracked, re‑sleeving prevents intermittent faults down the track.

Replacement is straightforward on most 2011 Mondeo engines:

1. Disconnect the battery negative terminal.
2. Locate the CMP on the cylinder head (often near the timing cover, some engines have one on each cam).
3. Unplug the connector, remove the retaining bolt, and ease out the sensor. Catch the O‑ring.
4. Lightly oil a new OE‑quality O‑ring, install the new sensor, and tighten the fastener to workshop spec.
5. Reconnect, clear DTCs, and perform any required relearns with a scan tool.

Quality matters—cheap sensors can cause ghost faults. If the Mondeo throws a cam/crank correlation code again after fitting, inspect the timing drive and VCT solenoids as advised in the Ford manual before blaming the new sensor.

Does a 2011 Ford Mondeo have one or two camshaft sensors?

Depending on engine, it may have one or a pair. Many Ti‑VCT EcoBoost petrol variants use two (intake and exhaust), while other engines can use a single CMP. A quick check under the engine cover or by VIN in a Ford parts catalogue will confirm what’s fitted.

Is it safe to drive with a faulty camshaft sensor?

The car may still run, but it can be hard to start, drop into limp mode, or stall. Continued driving risks poor fuel economy and potential DPF/catalyst issues. It’s best to diagnose and replace the sensor promptly.

What are the common fault codes for a Mondeo camshaft sensor?

Typical codes include P0340 (circuit malfunction), P0341 (range/performance), P0344 (intermittent), and sometimes P0016 (cam/crank correlation). If these appear, check wiring and the sensor before diving deeper.
