Car is a 2011 titanium X 1.6 ecoboost, 45k miles. Engine management light has been for around 2 weeks now and took it to the garage on Thursday to have a look. I had already checked the code myself, which came back as above. Car doesn't have a fuel filter so they treated the injectors with a cleaner and cleared the code. Also had a service and the engine does feel a lot better now - before they were was some hesitation above 3k revs, not quite a misfire but just lacking in power at some points.

However, the engine management light came back on the same night I picked it up from the garage but the car was still warm. All the possible symptoms of this fault code - difficult to start, rough idle, misfire, hesitation - are not there so I thought this may be down to a sensor being dirty/corroded and it's throwing up a code because it can't read the engine properly rather than an actually problem.

Which sensors could this involve and where would be the location of these?

TIA

    does it definitely not have a fuel filter? i am not familiar with this engine but do they really sell these cars with no fuel filter? I would have thought they would all have problems if no filter

    No, I suggested to the garage the fuel filter might be the problem and they said it didn't have one.

    Many petrol engines don't have a filter, simply a 'strainer'.
