[Pgm fi light 2009 2.2 cdti]

Went to buy a 2009 accord 2.2 

139k

But it has this warning it drives OK

Has no engine management light a cheap obd tool didn't say anything 

But it seems to relate to fuel injection system.

I can't take it to a garage as its not my car the car is priced accordingly .

Could this be a real headache should I stay clear or u think it will be something fairly manageable in your experience of hondas

Thanks in advance 

There is very little regarding this on Google
