Hey guys. First time on here. Thanks for all the info I have been able to read. Having a problem with my 99 Camry 2.2. Replaced the timing belt, water pump, radiator, thermostat, and the two temp sensors up top. Put Toyota coolant in, burped the system, but it is running too warm. I would say the temp is running between 70-85% right now on the gauge. Fans turn on. No codes in the system. It runs perfectly, just running hot. Heater and AC both work beautifully. Everything seems to be working correct....just hot. Have tried 2 different temp gauge sensors with the same outcome. I am at a loss and not sure where to go next. Have basically replaced the coolant system and it is not running at the temp it should. Any ideas on what to look at next? I was thinking maybe the timing has it running lean, but there are no codes and it sounds and idles like a top. Thanks for any suggestions or help.
Jumped the sensor....didn't change anything. So the ground fault must be in the actual cluster.Sure, you can take a length of wire, and jumper from the gauge sensor body -> directly to battery Negative (-) terminal, see if the gauge improves.
You've done a lot of motor work, just want to reiterate what I stated above:
I would also be using an OBDII scanner adapter / app. to real-time monitor & confirm coolant temp., as reported by the ECT sensor, while going through this diagnostic.
At a minimum, check & confirm your temp. readings w/ the IR Thermometer when @ operating temp., to ensure nothing has "changed" on the coolant system side.
I'll check those grounds. I have done the passenger fender one already, but haven't done those on the bottom of the intake manifold. I'll check that next.Would suggest getting the Alternator and Battery (load) tested. ... If any doubt as to the condition of the Ignition Switch, perform voltage testing there also.
you also mentioned a "flashing check engine light" above - that indicates a engine Misfire rate, severe enough that the (ECM) is alerting the driver (you) to potential Catalytic Converter damage, due to unburned fuel entering the exhaust system. ...
There are a series of grounds coming from the engine harness (about mid-point back of motor / that route down between the Intake Manifold / fuel injector rail) -> to the bottom of the Intake Manifold / where the EGR VSV sits on the 2.2 here, and another ground strap from the motor over to the fender well on the passenger side in the engine compartment.
Go back and review: make sure -all- grounds removed during engine work have been properly reinstaled / cleaned / and tighened - I would, if here.
Haha. I am about to go grab a new set of NKG wires and plugs in a minute. Gonna get new for that. Tomorrow I will grab the MAP. Was planning on grabbing the charcoal canister too. For the ignition switch are you meaning the key ignition cylinder inside the car? And I thought the EVAP VSV was attached to the charcoal canister in the back of the car.I'm guessing there is (some form of a) rubber diaphram assembly inside the EGR valve - as it is modulated by vacuum. So yes - grab another EGR valve. They do go bad after getting crudded up. Cleaning is sometimes a "hit-or-miss".
Also grab the Coil Packs, and ignition wires if they look good. (Battery short / arcing)
And the MAP sensor. (Hesitation)
And the (electrical) Ignition Switch, if available / you have time to do so. (Temp. Gauge diagnostic)
And the engine compartment EVAP Purge VSV, w/ vacuum hose(s) to the Throttle Body. And the Charcoal Canister assembly. (EVAP DTC)
It may be easier to just hook a chain to the back bumper - and drag the car back home w/ you, LOL.
My bad, Purge VSV then. (The other one.) ..Haha. I am about to go grab a new set of NKG wires and plugs in a minute. Gonna get new for that. Tomorrow I will grab the MAP.

I appreciate all the help for sure. I have done some of what you said, but not all, and not in any specific order. I just replaced the battery and terminals I know that is good. But beyond some jiggle testing and light visuals I haven't gone through anything.If you have read this far: congratulations. Above is a lot, adapt it to your own plan as needed, shout out w/ any questions, will try to help.
