Hi everybody, I have a question concerning the mass airflow sensor. This is more of a curiosity thing for me at this point. So the original MAF for my car (2002 sentra gxe 1.8l) malfunctioned and from what I can tell, the J shaped silver wire in the middle of the inner component is gone (see the sample picture below-it is the thing that looks kinda like a paper clip) [![](https://global.discourse-cdn.com/cartalk/original/3X/8/f/8fa5e42bbd495b42c5ef78d1817f6b721776c2f2.jpeg)](https://postimg.cc/4KVjmXC1) I guess that is the hotwire of the MAF? I am wondering if I can get a hold of one of these things and solder it on,will the MAF work again (assuming that is the only thing that is wrong with it). I mean I already got a replacement MAF so this is more like a “what if” for me. Many thanks! ---

Nope! Tester ---

I think soldering the wire on will probably change the resistance. And I think that’ll screw with the data the computer gets from the MAF, if you can even get it to function at all. That’s my theory, anyway. ---

The hot wire is made of platinum. In order to solder platinum requires a jewelers torch.

If you can solder that wire without melting the plastic of the sensor, you’re a better metal joiner than me! And it also changes the resistance of the wire. Tester ---

Wasn’t aware it was made of platinum. No wonder those sensors are generally a little pricey. ---

ok. Many thanks for your reply!
