Default OHC Temp Sensor or EATC or Ambient Temp Sensor?!

Okay, so I stopped by the junk yard today and pulled an OHC from an Explorer. When searching around for the temp sensor I found conflicting images and posts about what was what.
Both of these guys have blue/white and blue/yellow wires.

Here's a pic of both the sensors I pulled.


I've read that #1 is the EATC sensor and it makes the console readout much lower than actual.

Whats the deal? Are these the same thing but just from different years or something? I came across maybe ten of the #1 sensors but only found ONE of the #2 sensors.

The #1 sensor has a part number of 12A64 7-AA but the #2 has no part number I can see. Anybody know the real deal with these?

Thanks!

I think those are both the same. The EATC sensor is the one with rd/bk, bk. I believe

The two sensors are used by Overhead Console?
Did sensors manufactured in different years can cause read errors? 1997 Overhead console + 1999 Temperature sensor = Error temperature?

No they work the same.

You can get a aftermarket one at auto zone and they work the same.
