Posted October 23, 200915 yr I have a 1999 Escort finesse 1.6. On the plastic pipe which runs from the air filter to the engine, there is a sensor screwed into the centre of it and I have broken the wires. Car still runs fine and there are no dash lights on Anyone know what the sensor is?
October 23, 200915 yr sounds like the MAF to me? is it on a metal bracket on the pipe that comes out of the air box? you need to replace it as the car wont run "properly" its running on a backup map. the wires you broke (if the ones i think it is) run the Mass Air Flow sensor which tells the ECU what air it is taking in/needs etc. the car will be running on a factory setting which will mean its not running efficiantly.

Its a lot further up the plastic pipe. About 30cm up from the air flow meter
October 23, 200915 yr http://www.evo-host.co.uk/getimg/21852.jpg can u put a circle on this pic and post it back up? only thing i can think of off the top of my head is the sensor at the back just before the pipe goes intot he throttle body?
October 23, 200915 yr Author i cant circle it at work as i cant access any programs to do it, but its the one directly underneath the passenger wiper arm fixing.

October 23, 200915 yr Author now im gonna sound stupid because iv forgotten its name ...but you do need it yes lol cheers mate. I blew it apart with the jetwash when I was cleaning the engine bay. Strange as the car still runs fine
October 23, 200915 yr cheers dave im not sure exactly but it may effect starting in cold weather or cause the car to run to rich when it warms up. Edited October 23, 200915 yr by KNITERIDER
October 23, 200915 yr Author Inlet Air Temperature sensor (IAT sensor) cheers mate. What does it actually do as I see no difference now its broken to when it was fine.

Strange as the car still runs fine no worries mate. thats why i wont use one, one because my escort might fall to pieces and two because they nacker electrics up lol Inlet Air Temperature sensor (IAT sensor) cheers mate. What does it actually do as I see no difference now its broken to when it was fine. see above thats an educated guess btw not gospel
