Front diff temp sensor

It’s true any time there is no wheel spin, paved or unpaved.

It also applies to braking, which is front biased, but when in 4WD is fixed between F/R, meaning the front brakes are not only slowing down the front wheels, but also slowing down the rear wheels through the front diff.

Just something else to consider.

Mine is a 2019 I don't have one.

 

I’m not sure what that has to do with TOYOTA removing the front diff temperature sensor or why they feel it’s no longer needed. My response to it is geared to suggesting that the front diff work load is not as hard as the rear for most normal use, but in dry pavement it might be an issue, which I know it is due to friction.

 

My original post was about why front differential temperature may be more of a concern to monitor than rear temperature. You're right though, during intended use, off road, low speed, it is unlikely there would be overheating of either differential.

That said, many people buy the Tacoma, and there's a very real scenario where people will operate in 4WD while at higher speeds. I could see the case to be made for a temperature sensor to monitor front differential temperatures and deactivate 4WD if the temperatures get above a threshold. That is likely why Toyota added the temperature sensor to the Tacoma.

My other posts were in relation to your assertion about loading applied to the front and rear differentials, and I was adding insight/knowledge about how the loads are applied to the various components under varying conditions.

(PS: You know it's just spelled "Toyota" right? There's no need to type it in all caps.)

Ah! Got you!
I guess now we need to figure out if we can even put one (front diff temp sensor) on, for the guys who'd like to have one. Seems like if the wiring is there and one can be installed, a dealer level scan tool may be necessary to let the ecm know

 

Incase anyone is wondering. Mines is a 2017 DC TRD off-road and it has the sensor

 

Did it throw any codes or dash light from being missing?

 

i can second you . I also have it on my 2017 dbcb trf offroad

 

No codes at all. I didn't notice it until I was doing my oil change after warranty changes were over.
