In my experience, a Hall sender either works or it doesn't work, with no middle ground. There is no gradual lessening of its functioning, although it can function intermittently. A queefed out Hall sender can cause the van to just die and not restart, a condition you can only hope for. A failing Hall sender can show various symptoms: at times, a longer cranking period when starting; a "no start" condition with the van then starting a couple of hours later and continuing to start for a month; the van starts a dozen times over a period of an hour, then never starts again; the van hiccups while underway. The early warning stage appears to be if the van sometimes takes longer to start then you are accustomed to and a hiccup with the tach dropping to zip while you are driving. A reboot won't clear a faulty Hall sender even for a few minutes. George |
