…lets the signal provide less voltage to the ECU, and the signal’s amplitude will be lower. The ECU interprets this as a too lean mixture even if it's ok and increases the duty cycle.
It’s ok for testing purposes, but it still compensates for a fault on the CIS side, so the real solution is to fix the existing problem.
