Parts for your 2016 Ford Focus-Camshaft sensor

2016 Ford Focus camshaft sensor — what it does, and how to keep it happy

Yes, the 2016 Ford Focus uses a camshaft position sensor (often one per cam on Ti‑VCT/EcoBoost engines). This is confirmed in Ford’s Workshop Manual for the Focus (WSM 2015–2018), Motorcraft service information/ETIS, and major repair databases (Autodata, Mitchell1/Alldata, and Haynes). Those sources list diagnostic trouble codes (P0340/P0341/P0344/P0365 etc.), test procedures, and replacement steps for the Focus cam sensor, making it clear the part is fitted and essential.

On a 2016 Focus, the camshaft sensor feeds the PCM exact cam position so it can sync fuel injection and spark with crank position, and control variable cam timing. The result is smooth starts, stable idle, good fuel economy, lower emissions, and decent go when the pedal’s buried. When a sensor or its wiring plays up, the Focus can get hard to start, feel doughy, surge at idle, or throw a check engine light.

It’s not a scheduled service item, but it is smart to give it a quick look during routine servicing. Under the bonnet, the sensor(s) sit at the cylinder head by the timing cover or valve cover area (location varies by engine, some have one sensor, some two — intake and exhaust). Check for oil wicking into the connector, brittle loom tape, or a cracked locking tab. Keep the connector clean and seated firmly, avoid forcing probes into terminals. If replacement is needed, it’s usually a simple remove-and-refit: disconnect the battery if working near live circuits, unplug the connector, remove the retaining bolt, twist the sensor out, lightly oil the new O‑ring, seat it squarely, and tighten the bolt to the service‑manual torque. Clear codes and verify with a short road test and live data.

• Typical symptoms of a crook cam sensor: long crank/no start, rough idle, reduced power, poor fuel use, and DTCs like P0340/P0341/P0365.
• Prevention: correct-spec engine oil and timely changes (supports stable cam timing), tidy wiring, and quick repair of any oil leaks at the rocker cover.
• When in doubt: scan it. A proper diagnosis beats parts darts every time.

FAQs

Does a 2016 Ford Focus have a camshaft sensor?
It does. All 2016 Focus engines (1.0 EcoBoost, 2.0 GDI, 2.0 EcoBoost ST, and 2.3 RS) use at least one camshaft position sensor, and many have two — one for each cam on Ti‑VCT setups.

Where is the camshaft sensor on a 2016 Focus?
It’s mounted on the cylinder head near the timing/valve cover area. On some engines it’s at the front of the head, on others it’s at the rear by the gearbox side. Look for a small sensor with a single retaining bolt and a two‑ or three‑pin connector.

Can it be driven with a failing camshaft sensor?
Sometimes it’ll run in a limp or default strategy, but starting, performance, and fuel economy can suffer — and it may stall. Best to diagnose and repair promptly to avoid getting stranded.
