Jtrek977 Posted March 19, 2021 Share Posted March 19, 2021 Hi everyone, I really could do with a bit of help as my focus has been acting up. Esp light comes on, turn engine back off wait 5 mins and it usually disappears. When driving it's in limp. Occasionally eml comes on too but not every time, maf sensor was replaced a few weeks back, a genuine ford part. Taken the car to a garage this afternoon and had it scanned. Fault code was u2023 Communication error. Has anyone had this sort of problem before, I need help!! Quote Link to comment Share on other sites More sharing options...
Luke4efc Posted March 19, 2021 Share Posted March 19, 2021 Are you running an induction kit? They can be known for triggering this code. Quote Link to comment Share on other sites More sharing options...

Hi buddy, yes it has ram air filter with wisbech engineering crossover pipe I do plan on changing the filter as I've found out recently these still let quite a bit of crap through, which all sticks to the maf sensor. Thanks for your reply. Quote Link to comment Share on other sites More sharing options...
