Parts for your 2017 Ford Mondeo-Camshaft sensor

2017 Ford Mondeo camshaft sensor: what it is, where it lives, and when to replace it

Yes, the 2017 Ford Mondeo does use a camshaft position sensor (often shortened to “cam sensor”). Ford’s own Workshop Manual for the CD391 platform (Mondeo/Fusion, Section 303-14 – Fuel and Engine Controls) outlines the Camshaft Position (CMP) sensor’s description, operation and test steps, and the Ford parts catalogue lists CMP sensors for the 1.5L and 2.0L EcoBoost petrol and 2.0L TDCi diesel variants. Independent data providers such as Autodata and Haynes also document CMP sensor diagnostics and locations for the 2017 model. So it’s absolutely relevant to the 2017 Ford Mondeo.

On this Mondeo, the camshaft sensor keeps the engine control module in the loop about cam timing and the exact position of the cam(s). That lets the ECU fire injectors and spark at the right moment and control variable cam timing properly. The upshot is easy starts, smooth idle, decent fuel economy and tidy emissions. Depending on the engine, there may be one sensor or two (intake and exhaust) mounted on the cylinder head near the cam cover.

It’s not a scheduled service item, so there’s no regular replacement interval. That said, clean oil and timely services under the bonnet help the cam timing hardware behave, which reduces the chance of spurious cam/crank correlation faults. During routine servicing, it’s worth a quick look for oil weeps at the sensor O-ring and to make sure the connector and wiring aren’t chafed or loose.

Common signs the 2017-ford-mondeo camshaft-sensor is unhappy include:

• Hard starting, misfires, rough idle or stalling after start
• Sluggish throttle response, poor fuel economy or limp mode
• Check Engine Light on with codes like P0340–P0345 or a cam/crank correlation DTC

Diagnosis should start with a scan for trouble codes, visual checks of the plug and loom, and a quick check of engine oil condition and level. If the sensor is faulty, replacement is straightforward: remove the engine cover, unplug the connector, take out the retaining bolt, swap the sensor with a new O-ring lightly oiled, refit and tighten to factory spec. Clear codes and perform a road test. On engines with two sensors, replace only the one confirmed faulty unless testing suggests both are compromised.

A quality OE or reputable aftermarket camshaft sensor is recommended. It’s a relatively affordable fix that can save a lot of mucking about with cold starts and erratic running, and it keeps the Mondeo’s variable cam timing working as the factory intended across Aussie and Kiwi driving conditions.

FAQs

Does the 2017 Ford Mondeo have one or two camshaft sensors?
Most 1.5L EcoBoost engines use one sensor, while many 2.0L EcoBoost and 2.0L TDCi variants use two (one for intake and one for exhaust). Always check the engine code and a parts lookup for your exact VIN to be sure.

Is it safe to drive a 2017 Mondeo with a bad camshaft sensor?
It might start and run, but it can stall, run rough and use more fuel. Prolonged driving can stress other components. Best bet is to scan it, confirm the fault and sort the sensor promptly.

How much does replacement typically cost?
Parts pricing varies by engine and brand, but the sensor is usually modest in cost and labour is light. Expect a short workshop visit—often less than an hour—plus a system scan and code clear.
