Is there a difference between the engine temperature sensor and the engine temperature sending unit in a 1999 Toyota Camry?
Yes, there is an air charged temperature sensor..http://www.youtube.com/watch?v=jzRpAjP7QKo......and a coolant temperature sensor...http://www.youtube.com/watch?v=AThAioyjg60
On some vehicles yes. The temperature sensor is for the computer. The temperature sending unit is for the gauge on the dash. Sometimes a vehicle will have both. Other vehicles use the temperature sensor for the dash gauge as well as for the computer. HTH. -Jim
