All the sensors on this jeep run off the same feed from the pcm I believe it is 5 volts. Check the hotside of the maf sensor and see how many volts you have there. I had this same problem and the wire was broke in the harness somewhere. I just tied into the wire right off the pc and down into the harness before it split to all the sensors. Hope this helps please let me know. Curt
