Hi,

If you look at pic 2 below, I highlighted the sensor. They are mounted on the cylinder block. I highlighted sensor 2.

Also, in the pic I attached, you are looking up at the engine from below the engine oil pan. If you plan to replace one, I suggest doing both at the same time. Otherwise, you will likely be doing the other one in the not-too-far future.

Let me know if this helps or if you have questions. Also, if possible, I recommend getting a quality part. OEM is the best, but don't get something inexpensive from online. I have been seeing a lot of issues with the low-priced electrical sensors and components.

I hope this helps. Let me know if you have other questions.

Take care,

joe
