The resistance spec is 800 to 1100 ohms, if you're checking with a DVOM. I would check across the two cavities of the PCM connector directly first. If this checks out good, you could voltage drop test the circuit by disconnecting the connector from the CMP sensor first, and plugging in a big light bulb (be careful not to damage the pins of the connector) and then connect a battery on the PCM connector for the CMP circuit. For what it's worth, this circuit CANNOT be repaired or overlaid because it is ground shielded, so if you find a problem with this circuit, be prepared to replace the entire engine harness itself. I've already replaced MANY, including one on an E-Series this last three days.
