MAF Sensor

(1/2) > >>

Hightower:
I have been getting progressively more concerned at the lack of mpg I'm getting from the car recently.
After some browsing through the web I've found that the culprit may be the MAF sensor.  If it's faulty it can lead to incorrect readings being fed to the ECU which in turn overfuels the engine.  End result, poor mpg.  It may also account for the rising levels of black smoke coming out of the rear end on acceleration.
I did have a look at it, and it does seem very grubby.  Now, can I clean this sensor and if so, how?  Not sure if there is any way of actually testing the sensor to see if it's working correctly before I decide whether to replace it or not.
Any views would be most appreciated.

You really need to get it on Testbook to find out.

My Td5 had a faulty manifold pressure sensor, so the ECU was getting confused as to how much air there was.

It might be that the a reset of the fault registers will cure it.

Hightower:
My man in Rushden had to send his Testbook back for fixing today but is expecting it back on Wednesday.  I'm gonna pop back over there then to get it checked out.

He didn't seem surprised that it could've failed either.

Oh well, another thing to fix  :(

td5disco:
I'd go with the Air pressure sensor on the inlet manifold

Hightower:
Thanks guys.

You don't happen o know the part number of the air pressure sensor do you?
Rather ask than go thru the pain of H@rtwells parts dept YTS staff!!
