I have a b max from 2015. Engine malfunction light came on. Took the car to a friend of mine, who hooked it up to the computer. The car was reporting airmass sensor fault. I've changed the sensor and tried resetting the car, but the engine malfunction warning comes on straight away, still reporting same problem. Any thoughts anyone????

could be the wiring to the sensor, try cleaning the connector.

when you say, 'resetting the car' what do you mean? (disconnect battery for an hour?) or clearing the fault codes?

Connectors look fine! By resetting, I mean deleting fault codes. A friend of mine, who is a mechanic, told me, it might be the wiring. In that case, I probably need to get a hold of a wiring diagram. It might be worth mentioning that the ""city engine start/stop""� function is no longer avalible. The engne is stuck in safety mode ˜«
Is it safe to rule out any fuses or relays being faulty?Edited by: Herik

first sensor was orgigianl. I replaced it with an unoriginal one. The OBD-II shows no reading from the sensor. Tried disconnecting it while car was running, nothing happended. Is it possible to buy a wiring diagram on the internet?

ford make the wiring diagrams available to 'independent operators' ie typically garages, but can be home mechanics etc.they charge 15euro for a days access to them

I only ask, as when a sensor failed on an Accord I owned, only a genuine sensor would stop the fault light coming on.
