O7 crankshaft sensor location

I have a 2007 tundra 5.7lt crankshaft sensor comes on after the truck sets for 30 days. Any answers for this issue.

 

May be a battery drain? low voltage may trigger weak signals to certain components triggering a CEL, What is your mileage??

 

Here's a link to where I posted a picture of where the sensor is located

It has 127.000 miles
I think it may be cause it sits a month at a time. I always have to put a charge on the battery before i start it. Thx for your info.

 

If it sits outside make sure mice are not getting to make a home. The damage they will do is tremendous.

 

My truck sits in a garage
I do have rats poison set out for the varmints.
