Coolant Sensor Acting Up
I recently picked up a 99 f150 4.2l 4x4 and it had ecu codes that were fixed by replacing fuse #23 (o2, cam sensor, egr, etc.) and now for some reason im having cooling problems. the temp level on the dash panel will heat to normal temp.
However, after a few minutes of being stable operating temp it will continue to rise to red triggering the red lamp on the panel. It is not over heating, coolant temps are normal (210 range after a long ride). When this happens I can pull over, kill the engine and the gauge levels out back to normal temp range. Start it back up and it rises again after a few minutes.
This all occurred after replacing fuse #23 and I have no engine codes whatsoever. What should I do?
Thanks,
Randy
