C0634 ECM connector grounds
Hey all, I have ground continuity on pin 5, but pin 6 (power ground according to RAVE) does not have ground when vehicle is OFF. See attachment...the earth ground I was referencing to was a nearby chassis bolt-head.
There is no Pin 4 connected on my model - 2002 Disco II SD...
Should there be ground continuity?

Trying to see if I have a loose / intermittent ground. When troubleshooting newly replaced MAF (Lean Codes P0171 / P0174) I noticed the MAF Ground wire was a 10 - 15 ohms to chassis ground. Cleaned off the two ground tabs near fuse box and battery...but also looked at the ECM 9 pin plug CO634. Read pins 4 / 5 / 6 should be at ground.
