No! If you don't have software and cable to reset the TPS then leave it! Just asked if you touched it
But if you say that temp was more like 20C then i think the water temp sensor is busted. It should be over 3KOhm @20C.
But lucily the sensor is pretty cheap and car sensor will fit! Most car part shops should find a cross-reference part when you give them part nr WTS05 or for example Hella code is 6PT 009 309-291. Or maybe you can borrow the sensor from somewhere for testing
