[QUOTE="J Paul, post: 1024346, member: 18862"] This issue finally started to happen all the time with the temp gage going normally to 4 bars while riding then jumping to maxxed out with check engine lite on.Replaced the sensor and no change. Started looking at wiring harness-manual shows 2 dedicated wires for this sensor-and found wire rubbing on a pair cover bolt where it came out of main harness. I couldn't even see any copper showing but rerouted wiring and put on a piece of reinforced silicone hose from an aftercooler connection(I work for Cummins so raided my used parts stash) and problem is now gone.Hope this helps someone else with a single gage giving erratic readings.
