Thread: TD5 MAF Stuffed?

Check your fuse, and the wire running to the MAF...

Slunnie knows exactly which fuse it is...

Even an out of range MAF should be reading something...

Anyone nearby you know - try their MAF

well bugger me,
i didnt know you could save a log like that on the nanocom.
very handy. how do you do it ?

Thanks tombie

I did check the fuse (no 2 under the bonnet) and wiring looks ok, anything in particular I should be looking for there? I also gave the connector a clean, before plugging in again.

Goingbush I don't have the nanocom powered up so from memory.... at the bottom of the instrument read out screen towards the right side is a blue disk icon. Tap that and it goes to a file screen. Tap in a file name hit ok and ok again and logging starts. Tap the same icon again to stop logging and the nanocom will give an alert that the logging has stopped. You need to have an SD card inserted though. Plug the Sd card into your computer and you can open the file in excel. Note it is not a true csv file as it uses semicolons instead of comas as a delimiter but you can easily spread break it up into columns by selecting the data and using the text to columns command.

Cheers

I ran the Nanocom on the defender TD5 with MAF unplugged by accident. The Nanocom read air flow constantly as 4.0.

Strange, it also ran a lot better. The MAF had been reading low. I will try cleaning it, and then perhaps replace it.

Hi Steve,

I have a spare MAF that you are welcome to try. It is from my V8 but IIRC they are the same on the TD5.

We met a few weeks ago at LifeStyle 4x4 and I'm not too far from there. I'm also home all next week resting my shoulder...

Cheers

Thanks Ron, the offer is much appreciated. Yep I remember you and your tidy silver/grey d2

I just had a quick check on the Russian Microcat site and unfortunately the td5 and v8 MAF sensors have different part numbers and in the schematics look different as well. So it probably won't help in conclusively diagnosing the problem.

Good luck with the shoulder. I'm hoping to get away to Mt Jackson on the weekend with the club. Thankfully the sensor problem isn't a show stopper, and the car is running well.

JC thanks for your observation. I'll try running it unplugged and see if my readings change.


Cheers

Steve

Are they the same? I was under the impression that the V8 has a different MAF. They are also cheaper than the Td5 MAF.

Talk about doing the hard way.

In excel use Import > CSV File rather than open.

The import wizard allows you to select semicolons as the delimiter.

If you want to make life even easier got to td5 map suite
and grab a copy of Graphic Viewer CSV (at the bottom of the page).
