Woke to an alarm under hood

High pitch noise under the hood. Found goes off when pull EFI 1 fuse. It hasn't been driven in about a week. From my internet searches have found is a common problem but not seeing any solutions.

 

Your friend, the piezo. You'll find it between the master cylinder and the driver's fender. Round thing, wrapped in foam. Unplug. Replace.

Pulled it out and that did the trick. Peeled the foam off but no part number. On the black lead found this SP609LX5-15V-1001. Don't think will bother to replace it as we don't have a fob anyway. Thanks for saving me a lot of grief tracking that down.

 

Not a problem @Trapperpete52

You can get a replacement on scAmazon. I think the thread I linked has links to the part, or something similar. The Toyota part for 2000-2004 Tundras is this one.

Based on pics I found online, that may be a splice-in solution. Not sure. I think the same part on scAmazon is like ... $18 or less.

 

Mine hasn’t buzzed again in a long time, knock on wood.

 

Sometimes all you gotta do is blow em out real good, or shake the water out of them.
