MAF Connector

[mffarrell]

My MAF connector is missing the locking plastic piece. Where can I purchase a replacement connector plug?

 

Thanks!

I would just leave it as is, I have broken clips all over the car and they stay together, you might get into more trouble changing out the plug than just leaving it alone. Porsche should rethink this failure.  While I'm on a rant there's no consistency on how to release the various electrical plugs and when you do there's a good chance you're going to break one of the release tabs.

Thanks! I wasn't planning to change the plug, I just need the locking piece that comes off the connector.

Maybe you can find one here...I didn't bother to search. http://www.wiringspecialties.com/mafsconnectors.html

Something to contemplate when working on any low or fractional voltage sensor harness: Do not use simple crimp connectors to join wires when replacing harness connectors.  Most crimp connectors are aluminum, and the wires copper, so over time you will develop dissimilar metal corrosion between the two, and the car will develop odd problems like stalling for no reason, fluctuating idle issues, etc.  We have seen this happen on several DIY  MAF harness repairs.  The fix is simple: cut out the crimp connectors to expose clean wire, slide a shrink tube section onto one wire, and then solder the wires together using rosin core solder.  Then move the heat shrink tube into place and heat shrink it to form a weather tight connection.  The idle and low RPM response problems will vanish and never come back.

 

The problem with crimp connectors and their inherent corrosion issue is that the DME relies on a very low voltage signal from the MAF, and any corrosion can significantly alter that signal, leading to problems.  With soldered connections, the signal will always be pure.

Thanks, but no luck.

JP do you know where I could ge a replacement without purchasing the wiring loom?

Most of the wiring connectors used in these cars are VW/Audi parts, and while Porsche does not sell them separately, VW and Audi do, as do aftermarket vendors as well.  You need to try to identify the connector part number and search the internet.  You can also try some wrecking yards.

JP I have been doing exactly that without any luck. The #s on the connector don't seem to mean anything, but thanks!

Have your taken the old connector into a VW or Audi dealer and asked them to try and match it?

Yes. My dealer suggested that I go to BMW

Can you please post a picture of the plug that include all the number? I might be able to come up with a source.

Thanks! I have searched high and low.

Please pull the rubber boot and look for other part numbers. You might have to remove the plug and look at the other side too. Also take a picture of the pin out of the female side.

This website should have what your looking for. Just match your plug and pin out.

Thanks! I saw this website last night, and I was going to take a chance and order one.

I found one more source. scroll down the page and look for  1-to-6 Way Weather-Proof Multi-Connector Kits
