Hello. I replaced the Crankcase Heater -Comes Complete in a Hose Assembly.
When i measured Voltage across the 2 pin plug there was .30V present.
When measuring ground on engine and power on the red wore of the Crankcase Heater plug, 12 volts is present. So, i figured to replace the Crankcase Heater. Still has the same issue and code won't clear. The power side is good.
There is a NTSB Emissions Bulletin that says there is a Calibration issue inside the DME that may require a calibration upgrade(reflash). It also states to verify the integrity of the circuit from the Crank Case Heater and DME.
My Question to you guys' is could you provide me with a Circuit Schematic for the Crankcase Heater-White Wire to DME is what i need to trace. I'm helping out a coworker.
Any help is much appreciated.
