What is sensor mounted inside grill above headlight?

What is this sensor? Mounted above driver side headlight. The wire from it runs through the firewall.

 

Ambient temp maybe?

 

Maybe. Base model truck, so pretty basic on instruments.
Ultra-gauge shows an intake air temp sensor,but would think it is located in air intake. This one is above driver side head light.

 

Definitely not an intake sensor..

Not sure. I'd imagine ambient temp is on all the 2015s, but Toyota can be an odd woman.

Hopefully someone knows for sure. Maybe @Jeff Lange

 

That was my first guess too, but ambient temp sensor is greyed out on the Ultra-Gauge temp sensor list....but I have lots of cat temp sensors.

 

stock ambient temp is directly in the center of the truck infront of the radiator on the vertical radiator support.

2014 / 2015's do not have outside ambient temps stock.

No idea what that is. Do you have an aftermarket rear view mirror with temp readout? or an aftermarket alarm.

 

I am second owner, so not sure. Do not think it is rear view mirror. Looks pretty stock and basic. Possibly an alarm.

 

Sucky driver sensor..... probably goes off every second on the road

 

Isn't that hood latch release cable holder?

 

If that were true, I would rip it out for sure because it would be on constantly!

 

Possible. I just assumed it was a sensor. Now I need to go take another look....and feel like and idiot if that is what it is.

 

I have had my hood up maybe twice since I bought mine. I may be mistaken.

 

Looks like the cable for the hood latch. Goes through the firewall right by the brake master cylinder.

 

It is. I feel like an idiot for not looking closer.

 

Glad to see am not the only one here with the occasional brain fart.
