2000 Toyota Camry Temp gauge reads high?

Question type: Maintenance & Repair
Temp gauge reads high but engine doesn't appear to be overheating. Replaced the single wire temp sendor twice with the same result. I ohm out the sendor and it ranges from 500-77 roughly. the fans kick in and drop the temp to the hoses (using a laser temp reader) Not sure where to go next? (radiator less than a year old, as well as coolant and upper lower hoses)

Did you change out the thermostat? Have you checked the coolant levels? If the original thermostat, I'd say it's time for a change.

Levels are good. I'll throw a t-stat at it and see what it does. I am getting heat at both radiator hoses though, with a temperature differentiation between upper and lower and seems I have good flow and the radiator is doing its job.

Ok new thermostat and same situation. I don't think I mentioned that as soon as you start the car the gauge begins to move even when cold and before it reaches operating temp the gauge is just below the red and pretty much stay there. Any thoughts?
Classic problem- keep searching Sherlock- the gauges rarely go bad, but, who knows-

You might want to consider this. Go to RadioShack and purchase a POT of about the range you are seeing at the temp sensor with your ohm meter. Attach this POT to the wire and a GOOD ground of that single wire going to this CTS. I seem to remember it should be a YELLOW wire. Have someone sit in the car to observe the gauge. Dial in what you consider a "normal" Temp Ga. reading. Remove the POT and check and record the reading of the pot. Now attach your ohm meter to the CTS....and allow the engine to warm up checking your meter and the your Infrared Temp Gauge. at the upper radiator hose. You should be able to monitor the exact time the thermostat opens....and....when the engine reaches and maintains NOT(normal Operating temperature). How do yor reading compare? Get back to us with the results.
