Hi Miguel,

Having read about your plans to design an ECU, I thought you might want to know there is a difference between the function of that test point on LH2.0 (your listed car) and LH2.2. Same purpose - it reads the output of the lambda sensor's comparator ladder, but on LH2.0 it is an unbuffered nmos output where on LH2.2 there's a transistor with pulled-up collector out to drive an LED tool.

With that test point you can view the ECU's decision between lean and rich from the lambda sond.
