Measure resistance between lambda housing and battery ground.
100 Hz lambda frequency? Whats that? Measurement error? Its about 1 Hz.
0.4 volts with multimeter is not normal.
There is a joint behind lambda with 2 bolts. Could be corrosive.
Check coolant sensor resistance .
I think, you are a bad influencer on your car.
To open bubbling coolant reservoir to flush electricity is just one of many failures.
