Got a scanner for the renix jeep system. And it was saying that at 194 degrees it still was in open loop. What could cause this?

Wonder if another input is not in spec preventing closed loop operation? Intake air or throttle position?

Very well maybe. The O2 voltage was at 0 and would spike once in a while

Did you try a new O2 sensor?

It's on the mail. I found a fsm that sort of gave me a value it's supposed to be reading and I was getting nothing.

Update the O2 has been replaced and its metering now but I must have a vacuum leak some where because it'll be rich and almost stall but recover. Also floods and I have to give it gas
