ford transit custom engine code issue advice !

[bluesky]

code reader on transit custom says mass air flow sensor fault . new one fitted by me - does the engine management light need clearing before i can find out if fault has gone ?
any help appreciated !( or it goes into the expensive dealer !!!).

Normally the fault will need clearing. Any garage these days will have the equipment to do it.

You need to reset the engine management light as the error will be stored until it is reset.
You can buy a cheap reader on eBay to do this.
