Hello .. thanks for the donation .. much appreciated
Try this couple of test's and let me know your results .. #1 speed sensor on ES300 is located on the rear of instrument cluster .. let me know
Vehicle Speed Sensors (VSS)
No. 1....In speedometer assembly. See Fig. 3 .
No. 2....On right side of transaxle housing
Vehicle Speed Signal
Vehicle speed signal is delivered to ECT ECU by No. 1 and 2 speed sensors. The No. 1 speed sensor is driven by differential and indicates actual vehicle speed. The No. 2 speed sensor monitors (magnetic pulse signal) the drive pinion speed.
NO. 1 VEHICLE SPEED SENSOR (VSS) TEST
Disconnect electrical connector from No. 1 VSS, located on top of transmission. See Fig. 1. Connect positive battery lead to terminal No. 1 and negative lead to terminal No. 2. Connect positive lead of voltmeter to terminal No. 3 and negative lead to terminal No. 2. See Fig. 21.
Raise and support one vehicle front wheel. Rotate wheel and monitor voltmeter. Ensure voltage changes from zero to 11 volts. Voltage should change 20 times (1993 Camry) or 4 times (1993 ES300) per each revolution of speedometer cable shaft. Replace speed sensor if voltage dose not change as specified.

NO. 2 VEHICLE SPEED SENSOR (VSS) TEST
Disconnect electrical connector from No. 2 VSS, located on transmission. Raise and support vehicle so front wheels can rotate. Connect ohmmeter between terminals of No. 2 VSS.
Rotate front wheel. Note that ohmmeter needle fluctuates from continuity to no continuity. If reading does not fluctuate correctly, remove No. 2 VSS from transmission.
Connect ohmmeter between terminals of No. 2 VSS. Note that ohmmeter needle fluctuates from continuity to no continuity when magnet is brought close to sensor and then moved away.
Replace speed sensor if reading does not fluctuate. If reading fluctuates correctly, components in transmission for VSS must be replaced.
