hi i have a 1.6 zetec se focus mk1 51plate. been having problems with accelration lately so i went to clean the maf sensor but i don't seem to have one and there is no wiring near by to even indiacate there should be one can anyone shed any light on this please as im not sure wether it should have one or not

 

bump!!!!!!!!!!!!!!

 

Your focus has what they call a tmap sensor that replaced the maf sensor, its located on the inlet manifold.

What problems are you having ?? have you checked the emission pipe behind the inlet manifold ( T shaped) as they have a tendency to go baggy and split causing running problems.

 

If no maf sensor is present, then the vehicle has a map-sensor.

Check vacuum hoses for leaks and cracks.
Exhaust completely leak free? Especially the first part where the oxygen sensor is.
If correct have the dealer read the codes and check the sensor values.

 

All petrol models have a MAF, Diesels have MAP, im sure it is located near the T/B, with a wiring connector coming from it?

The later black top zetec-se ones 100% don't have a MAF!

 

It must have the tmap sensor inside the inlet then as described above I assume, never had to look, just going by what Haynes say!

thanks for all the replys. the problems i am having are when driving the car it will suddenly now and again start to hesitate and not acclerate as it should it feels like something is holding it back it revs fine but just want go anywhere and after a while it will go and the car will be ok again. i do have a eml light on and the codes are p0316 and p0141 but i cant find anywhere online to find out what the codes are .

 

No reply

 

i now have the same prob, did you get it fixed? was it the map as i replaced this and no joy but could not find a maf either. I have a mk1 1600

 

The early ones as said have a MAF, the later ones have a 'TMAP' sensor, which is located in the inlet manifold.

A faulty VSS is known to cause hesitation as well...
