Interesting, I’ve only seen that term used here on the 2.1, and the Bentley just refers to them as “temperature sender.”  Confusing, they are two different systems with one sensor each.

There is no temp 2 sensor on a 1.9, only the ECU sensor and the gauge sensor, both on the T-stat housing. 

 

Temp-II is the ECU sender you're referring to.  Temp-I is inside the AFM and measures air temperature.  They have identical resistance vs temp curve.

 

Yrs,
