P1102 MAF Code and CEL

[RandyH]

Finally tracked down my CEL with P1102 MAF code to an open wire (MAF return circuit pin 4) in the MAF connector plug on the air intake. Sounds like a somewhat common issue for the wires to break near the connector or where the MAF harness rubs on the frame under the battery box area going to the PCM. Had to replace the connector with a new pigtail. Soldered the six wires and used heat shrink to insulate them and all is well once again. Here's a great troubleshooting link for someone trying to figure this out.
