  1. Oil pressure sensor voltage is also 1.45v. Is there a ground that these two circuits use? Is there a ground the ecm uses somewhere I could check. BAT+ to CMP SENS+ showed 10v
  2. Haven’t check oil pressure sensor circuit yet. This truck has a 12v in it. I’m trying something with one of destroked kits to get the factory tach to read so the typical codes or issues you would get with a bad cmp sensor aren’t going to show. I just was/am a little confused with the low voltage
  3. 01 body/harness So if it is the ecm all 5v sensor supply circuits will be the same as the cmp sensor supply voltage? Also I’d like to add, coolant temp sensor gauge and oil pressure sensor WAS intermittently working, now nothing. Haven’t delved too deep into those issues as I have a/m gauges for those.
  4. I have to assume supply wire short to ground or bad ecm. Just wondering if anybody’s has some information
  5. What would be the culprit(s) for getting 1.45v at the VT/WHT wire right off the ecm for the camshaft position sensor.
