If you have a differance of about .2-.3volts, 2 volts is off the scale, as far as being close. You have a 5 V ref, and you lose 2V, that means you lost 40% of the signal. If it does not reach at least 4.75V, then the ECM will not identify the signal, the same also goes if it does not pull down to at least .25V, the ECM will not identify the signal. The ECM only sees OFF or ON, nothing inbetween. Now is your CKP a actual postion sensor or just a TDC sensor. A TDC sensor will only have one signal per rev
