Internet search says it is an "ignition capacitor". This fell out of the bumper cover when I removed it to replace the foglights. Obviously I dont think I broke it loose, probably just fell behind it when it was being replaced some time ago. Just wondering if anyone knows what it's used for.....

 

That suspiciously looks like the front air bag sensor for front crash.

 

The number on it is 56028644AB and what looks like a resistance range (250 - 0.47).

 

If you do a part number search on rock auto they say its a ignition capacitor too they even have a pic

 

I am almost positive that is used as a back up capacitor for the air back system in case the battery fails. Let me also add that I have never seen them in the engine bay, only under that dash. If you go to page 1845 of the service manual it might be the top picture location

 

then I should probably find out where it goes and reconnect it then. wonder if thats why I get a random air bag light sometimes.

 

yeah just looked it up its a Back up FAIL safe airbag sensor for front impact...not the main sensor but the back up incase the main does not work within so many milliseconds! so that may help!

 

yeah, now i just got to figure out where it goes and reconnect it...

 

haha good luck! look in the owners manual...maybe find it in there!

 

I get a random airbag light too, but Im not sure why. Last night I pulled in to the driveway and got an airbag light, parking brake light and an abs light. The codes say Im loosing connection with the different modules. It probably happens once to every 5000 miles or so.
