Okay its time to get technical-disconnect the EGR temp. Sensor get a voltmeter look for a 5vref. On the connector THG circuit-the other is ground-do you have power? The EGR temp. Sensor tells the Computer to open the EGR valve thru the VSV.
No 5vref we're looking for either a short or an open circuit all the way to the ECM>wire checks out for open or short-Think! ECM
Did you route the vac hose accordingly at the modulator?
Lets go back to the wiring circuitry: according to my references you have 2 (two) EGR temp. Sensors
1 @ left rear of side of engine with Green/Yellow wire for the THG circuit and Brown and Black for ground E2 circuit. Note: THG should have the 5volts.
2 @ left side of engine with Red and White wire for the THG and Brn and Blk for gnd.
Am I correct with 2-EGR temp. Sensor. For 96 Toy LC 4.5L 6cyl
Hope this helps/Good Luck
