yes, thx billr,I knew I was writing something wrong, and I knew someone would autocorrect.I fear there is some misinformation in the above. The driver for the CMP (or CKP) signal will be in the sensor, triggered by a Hall device in the sensor. The PCM side of those circuits is a high-impedance that is so well protected and so low power as to be nearly bullet-proof. The first transistor that signal is likely to see on the PCM side will be inside the PCM CPU chip itself.
ummm..... in English please lol3 = ignition voltage (YEL/BLK)... this is a big hint that the sensor pull-up is in the PCM or that there is active signal-conditioning, like a transistor, in the PCM for that input
