- 1997 ford explorer
I have a 1997 explorer 4.0.... pulled codes po135,po141,po155 on all o2 sensors. I'm getting no voltage at the o2 sensors with the key on and tried it when it was running to. The fuse for the pcm is good. I checked the voltage at the pcm on pins 93,94,95,96 and got nothing. I just want to make sure that im checking the pcm right. I removed the bolt from the pcm and located the pins on the wire side of the connector. Got nothing. I just don't want to replace parts.. PLEASE HELP
