Good chance it is temp sensor, but have the codes scanned and that will tell you for sure. Another sensor I have run across could be oxygen sensor, sometimes they will make the vehicle run bad and sometimes they dont but in either case is does affect fuel mileage. Dont think either way you need to avoid driving your car unless maybe temp sensor showed overheating problem. But dont wait too long to get code scanned.

The sensor is right next to the heater hose outlet on the front passenger side of intake manifold. It is very small with an oval shaped connector going to it. I have the same engine.

Coolant is low enough to trigger the sensor. There's a pressure leak somewhere in the system. The sensor is faulty.

As you say the tacho/speedo come "back up to normal" after the incident, I assume that they either stop working or become erratic while the dash lights are misbehaving.
If so, this sounds like a dash wiring electrical problem.
The O/D OFF light is lit by the switch on the shifter (switch also inputs to the ECU). The ENGINE light is driven also from the ECU but the SLIP light is driven from the ABS/VSC computer, although these two computers do communicate.
Best plan of attack would be interrogate the ECU for error codes or ask a Toyota dealer to do so. At least you'll have some clue to any problems that the ECU's may have picked up.
Contact me about checking for ECU error codes if you want to attempt it yourself. Although the Caldina has an OBDC2 connector, as I understand it it's not 100% compliant, so you'll need a Toyota compatible reader. Fortunately teh codes are also output via the CHECK ENGINE light.
If there's no problems there, I'd be pulling the instrument cluster and checking for wiring problems. I'm not sure where in the world you are but most ex- JDM vehicles could have modified with timers, speed-cut or fuel-cut devices that either have been poorly installed or are playing up and causing electrical problems.
