Coolant Temp Sensor ?




Sensor resistance is dependant upon temperature:
210* = 185 ohms
160* = 450 ohms
100* = 1,800 ohms
70* = 3,400 ohms
40* = 7,500 ohms
20* = 13,500 ohms
This across the two pins on the sensor.

Sorry about the long post and many replys...I just want to knock off one problem before going to the next. I think I need a vacation from the Vette. And thanks for all your help esp. Pete who's been responding many times. Now I'm going to take a couple of Motrine and vegetate.






Could be the Dark Green wire coming from the sensor to the cluster is open. Being equal to or greater than 1600 Ohms, an open would give you a LO reading. To check, disconnect the Dark Green wire from the sensor and touch it to something grounded like the exhaust maniford. Switch ignition to on (no need to start) and the dash should read 330°F. If it does read 330°F with Dark Green wire from sensor grounded the sensor is bad, if it still reads LO, there is an open between the sensor and the cluster.
Good Luck.
By the way how is it having a Vette in the UK? Are there a lot of people gawking? Are there many Vettes over there?

I'm an ex US Navy submariner. Been working for Lockheed Martin for nearly 18 years and in the UK for the last 12 and a half. There are actually more Corvettes here than you'd imagine, but not too many to lose their exotic quality. You're more likely to see a Ferrari on the road than a Corvette! So the is the gawk effect.
