Haavard Guttormsen Posted January 18, 2009 Share Posted January 18, 2009 I have read somewhere on the net that the MAF sensor is just for EGR issues. Is this for real? If I remove (it is gone) the EGR system do I need the MAF sensor at all? I wan't to get rid of all the stuff I do not need in my setup.

Visit My Website No, you need it whether you have EGR or not. Try disconnecting it and see how your engine runs to find out. Doing that will not do any harm by the way.

cipx2 Posted January 19, 2009 Share Posted January 19, 2009 My advice is to read what a MAF sensor is. You can start here: http://en.wikipedia.org/wiki/Mass_airflow_sensor Then you'll be able to reply your own question. Quote Link to comment Share on other sites More sharing options...

At but the real purpose of the TD5 MAF is to tell Testbook that there's a fault when there really isn't!! Had three new genuine new ones and it still says there's a fault!! I heard of one customer who tried 6 from LR before he found a good one. Luckily LR accepted that they were shi*e so replaced them FOC.

Haavard Guttormsen Posted January 19, 2009 Author Share Posted January 19, 2009 The sensor in my car now does not work. It reads 0 volts on my Nanocom unit. I do know what a Maf sensor is, I'm just not sure all it´s functions in the TD5 diesel engine setup. Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted January 20, 2009 Share Posted January 20, 2009 I have never fitted a 'dud' new Air Flow Meter, out of about 5 or 6 so far. But it is possible to have a fault in the cable to the ECU. I don't know what exactly it does, but the engine runs a lot better when it is working. The normal reading at idle is 46-7 kg/min. When you rev it it goes above 100. Quote Link to comment Share on other sites More sharing options...

But the fact that a main dealer is prepared to replace 5 of them FOC says it all really!! Quote Link to comment Share on other sites More sharing options...
