Cannot find the speed sensors on the 3.8 transmission

O'Reilly show two but they look different. My searches show there are normally input and output sensors. I can find anything specific to locations though

And Autozone show them as Input and Output.

DTC P0717: Input Speed Sensor Circuit Low Voltage
If you don't know anything about automotive electronic's , sensor electrical circuit's ,your best bet would be to take your vehicle to a qualified repair shop.
Finding a wiring diagram ,reading how this sensor work's an testing the electrical circuit using a DVOM - digital volt ohm meter , going by a factory service repair manual .
Diagnostic Fault Information
Circuit/System Description
The input speed sensor (ISS) is a hall-effect type sensor. The sensor faces the 1-2-3-4 and 3-5-R clutch housing machined teeth surface. The sensor receives 8.3-9.3 volts on the input/output speed sensor (ISS/OSS) supply voltage circuit from the transmission control module (TCM). As the 1-2-3-4 and 3-5-R clutch housing rotates, the sensor produces a signal frequency based on the machined surface of the 1-2-3-4 and 3-5-R clutch housing. This signal is transmitted through the ISS signal circuit to the control solenoid (w/body and TCM) valve assembly. The control solenoid (w/body and TCM) valve assembly uses the ISS signal to determine line pressure, transmission shift patterns, torque converter clutch (TCC) slip speed and gear ratio.

Circuit/System Verification
Engine idling, observe the scan tool Transmission ISS parameter while varying the engine speed. The Transmission ISS parameter should change with the engine speed and not drop out.
Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Your best bet ,take it to a qualified repair shop.

Did you do the diagnostic's that go to that code ?

Ignition OFF, remove the control valve body cover. Refer to Control Valve Body Cover Replacement.
Connect the TCM harness connector.
Disconnect the input speed sensor (ISS) from the control solenoid (w/body and TCM) valve assembly.
Connect the J 38522 between the supply voltage terminal B and ISS signal terminal A at the control solenoid (w/body and TCM) valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test for further instructions.
Set the J 38522 signal to 8 volts, the frequency to 120 and the percent duty cycle to 50.
Ignition ON, observe the scan tool Transmission ISS parameter. The scan tool Transmission ISS parameter should be between 100-400 RPM.
? If not within the specified range, replace the control solenoid (w/body and TCM) valve assembly.
If all circuits test normal, test or replace the input speed sensor.

Control Valve Body Cover Replacement

Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement.
Remove the oil cooler inlet hose (1) from the retainer on the control valve body cover.
Remove the oil cooler outlet hose retainer nut (5) from the control valve body cover.
Remove the oil cooler outlet hose (4) from the retainer on the control valve body cover.
Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle.
Remove the left engine splash shield. Refer to Engine Splash Shield Replacement.
Drain the transmission. Refer to Transmission Fluid Replacement.

The transmission sensor or speed sensor is located in most vehicle located on the transmission case.These speed sensors are driven by a gear located on the output shaft. The speed sensor's driven gear can be either machined or fastened by a clip. The driven gear is made by plastic to make it softer than the drive gear. It's located on the end of the vehicle speed sensor.

Hi David,here's your speed sensor,it's mounted on your transmission,it controls the speedometer. http://www.autozone.com/engine-management/vehicle-transmission-speed-sensor/duralast-vehicle-transmission-speed-sensor/lexus/es300/1993/6-cylinders-v-3-0l-mfi-dohc/135932_0_20285

P0720-OUTPUT SPEED SENSOR ERROR

WHEN MONITORED
The transmission gear ratio is monitored continuously while the transmission is in gear.

SET CONDITION
If there is an excessive change in output RPM in any gear. This DTC can take up to five minutes of problem identification before illuminating the M.I.L.

p0733 Gear 3 Incorrect ratio

Your car is in "limp"mode because the computer doesn't know what speed your doing,So it doesn't shift,
There are three possible reasons for this,
#1= input sensor faulty on transmission,
#2=output sensor faulty on transmission,
#3=speed sensor faulty on transmission,
you need to have the transmission codes read to know which one,Autozone checks codes for free.

The speed sensor is on the tailshaft of the transmission,on the passenger side of the car,it has 3 wires. The output sensors are located on the front of the transmission about mid-way up the housing & only have 2 wires. Note the output sensors are not responsible for vehicle speed. Only the output shaft speed is recorded. They are for finding the correct cvi(clutch volume index) only. If you have a cvi issue,the transmission is toast.

HI..
The Speed sensor on your Honda Accord 97.
Is located on the Transmission.
If you follow the Lower Radiator hose from the rad to the engine.
The hose end on the Thermostat housing.
OK.. Just on direction of the thermostat housing .
Under the housing you Will see on the transmission the Speed sensor, with a connector of 3 wires. Is the only sensor at this
Part of the Transmission..

Ok. I hope this work on your question.
Thank you for use fixya..
