92F150 open loop question
I have a 1992 F150 5.0L E4OD trans. It is running in open loop all the time. I thought that after the engine was warm/hot it should got to closed loop.Am I right or am I wrong? I used a scan tool when it was hot and it said open loop. I am confused the o2 sensor is working as I watched the values on the scanner, engine coolant temp. was 190 degrees, intake air temp was 150 degrees and there is no trouble codes set. Any suggestions? Thanks a million!
