maf sensor

[keithg]

Im sorry Im sure this is not a new topic but I cant find where I was advised to unplug a maf sensor to check if functioning properly.
I seem to remember the post saying if maf is faulty the power will return.

I replaced the sensor about a year ago as considered faulty by this check and it was fine.

Now the fault has returned with new sensor I have unpluged and all is well again.

As I am travelling high miles for work at moment will I do any damage leaving it un plugged long-ish term till I can replace again

Thanks in advance for any advice

It will use more fuel and not run as smoothly as it should, but it shouldn't do any damage. However you're restricting the ECU from receiving an important set of values which is never ideal.

Hi and thank for the reply it seems to be running fine but does appear to be using fractionally more fuel, I will be replacing the maf sensor this week so am not talking about months,was just concerned about doing irreperable damage.
Thanks again

In that respect you are totally fine. Make sure to purchase a genuine (Siemens?) MAF filter, as opposed to the eBay cr*p ones as they are often faulty out of the box and even if they do work, they don't often work very well.

Thanks for tips, as I said I did replace it about a year ago with one from local spares shop and suspect it's as bad as ebay ones this time I'll get a good one from main dealer.

Having been told to get a good maf I have been offered from main dealer £136 from local spares shop a Hella for £81 and a Lucas for £65 are these prices about right? The one I got last time in my ignorance was a unknown make Masterflow! Can't find bill to tell what I paid.

I fitted a hella in mine with no problems, reputable brand and all that. I think OEM is now svo after some corporate buyout of Siemens.
Decent price that considering how much I paid for mine at trade!
