RE: 2000 Mazda MPV airbag light flashing
 

babyhuey - I'm back, I'm confused, and I need your help again please. [:@]
I finally ordered that O2 sensor and was just about to install in today and really got confused once I got up under the vehicle and started looking at the different sensors. I think I may have ordered the wrong part. I thought I ordered the part number you gave me above (GY04-18-8861b-9U) for the rear, downstream (or lower) sensor. What I got is GY02-18-861B-9U, which is front, lower. Here a picture of what I got (if they upload correctly). You can see the little plastic mounting tab on the wire harness, and I can see where this would go on the front sensor (see pic where my finger is pointing to mounting tab). The rear sensor that you pointed out does not have one of these tabs. Also, the partial part number on the sensors do not seem to match. The front sensor on my MPV has this text:

GY01
DENSO
08U20
-4120

The rear has this:

GY01
DENSO
06F21
-4110

The sensor I ordered has:

GY02
DENSO
07H27
-4120

The GY02 and the -4120 are common on my front sensor and the one I ordered.

I possibly ordered the part number that was on my original quote from the dealer, which was for a front lower sensor. That the code they said they were reading. After I had the manifold replaced, is it possible that the front sensor code would clear and then I would get the P0037 code for the rear?

I am getting a little confused now also djn. You should have an oxygen sensor in the top portion of each exhaust manifold which are the right and left side upstream sensors.
Looking back thru our posts I am not seeing any indication of your van being a california emssion or federal emission level so do not know why I have assumed it is california??? A california emission level van would have the downstream oxygen sensors just after the warm up cats. Both downstream sensors would be located on the engine side of that flexible metal braided part of the exhaust. The right side downstream O2 on a california emission van would be in the position just like in the pics below. Both pics are of the same sensor.
On a federal emission level van, both downstream sensors would be located in the exhaust system AFTER the braided metal flex pipe. Does your van resemble the pics?

Yes, mine resembles your pics, so it appears I have the California emission. Here's a pic of my van, more of a close up so you can't see the braided sleeve. The other thing that confused me was the location of the connector. From your previous post pics and description, it appeared that you accessed the connector from the top of the engine (near the coil). From my pic, you can see it from the underside, just hanging there next to the alternator. Maybe the yanked it down when they changed that manifold...

I think somehow I ended up with the GY02 (front lower) instead of GY04 (rear lower). Just spoke to onlinemazda and they are going to swap it out for me. When I went to put it in and things didn't match up exactly as I expected, I just got confused.

RE: 2000 Mazda MPV airbag light flashing
 

Ok djn. Just glad we got that clarified about how your sensors are set up. If it was a federal you would have needed a GY05. Looks like you are exactly right in that you received a GY02 which would indeed be the left bank downstream sensor near the radiator side. The GY04 should get you squared away just fine and glad to hear that onlinemazdaparts will do the exchange for you.:)

DJN : Can fix the air bag problem? I have the same air bag problem in my MPV. Do you replace the SAS module or fixed? Thanks for your help.
