I have a 3.4 L 1996 Toyota 4Runner 4x4. have had some issues with the temperature gauge being a bit erratic but now it's completely dead. I replaced the coolant temperature sending unit, warmed up the engine and got nothing. Then I replaced the entire dash cluster/temperature gauge, still no movement. I have checked the fuses inside and in the engine compartment. I ran a test that said I should ground out the wires from the sending unit and that should get a response unless the circuit was open. I take it the circuit is open somewhere but WHERE? I get power in the wires to/from the sending unit but from what I believe are the wires going into the adapter in the dash cluster, I get nothing from the inside. Is there a command module, chip, etc...... that I am missing bc I cannot find anything else about where else to look.

there are 2 senders, make sure you are chasing the correct one down

both on top of motor

one in front of the engine, that feeds the ecu, called the ECT

one in back of the engine, that is solely for the dash gauge, called water temp
