Just a reference for those who may not know etc and do not have a scope available.
Obviously not a fully conclusive test, but a good video explaining why it is a partial test of such sensors, and why a proper scope is king.
Of course this does not apply to a 2 wire VR signal....although during cranking you would still see a response from the meter, but it wouldnt really give any proper information.
Scanner Danner is a great resource too.
Discuss which Sensors work best with these ECUs and share how you are using inputs and outputs
