Engine Cooling problem
2001 Chevy Venture 6 cyl Front Wheel Drive Automatic 97,210 miles

CEL #1
Collant Temperature Indicator (Replaced Sensor)
Drove Vehicle 2 days Temperature guage working, took Van to AutoZone and had computer reset to get rid of the CEL.
Day 4 CEL #2 Took Van to Advanced Auto
Low Collant Temperature (? Help here)
The Tech stated that the collant temperature was not hot enough to register on the Sensor. He seemed very intelligent right up to the point when he started scratching his head. He suggested that the Thermistat might be stuck in the open position (? Help here)
Collant Temperature Guage not working on Dash

Temperature would still get high enough to read with the thermostat stuck open. It would atleast go a 1/4 to a 1/3 the way up.

I'm hedging on a bad wire in the harness to the temp sensor or dash.

Turns out it was not the Thermastat that was stuck open but one of the 2 relays that was amiss. Pulling and resetting the Relays on the PCM corrected the false signals and restored the Temp Guage to operation.
