I have a Peterbilt X15 Cummins engine and low coolant sensor comes on only when washboard I drive on and then sometimes goes off if I sit but other times it’ll stay on all day. The sensor has been replaced so that’s not it. If I unplug the sensor obviously it won’t go away since there seems to be a broken wire somewhere? But is there easy way to diagnose this? Or if I bypass the sensor would it keep the alarm from sounding that’s what I wanna get rid of.
