If its a manual transmission, it will not affect the power but you will get occasional check engine lights while running with the sensor unplugged. occasionally the throttle sensor may also cause your idle to run erratically.

This car is known for bad Instrument Clusters. Not to say that it is out of the question that your speed sensor could be bad... But 75% of the time it is the Cluster in the 1996-1997 Accord.. Car Part com Used Auto Parts Market
check to see if the wire has came loose leading to the seat belt disconnect button you push when releasing the seat belt if connected. then will have to replace that part of your seat belt the sensor or switch in buckle may have broke
The malfunction of your speedometer might be cause by the speed sensor in the transmission.
It might have been disconnected or needs replacement.
You must check that first to your mechanic, before pulling out the meter itself!
For 1997 Honda Accord 2.2L MFI
4cyl the Vehicle Speed Sensor - Location is located mounted on transmission. OPERATION The Vehicle Speed Sensor
(VSS) is a magnetic pick-up sensor that sends a signal to the
Powertrain Control Module (PCM) and the speedometer. The sensor measures
the rotation of the output shaft on the transaxle and sends an AC
voltage signal to the PCM that determines the corresponding vehicle
Disconnect the negative battery cable.
Disengage the wiring harness connector from the VSS.
Using a Digital Volt-Ohmmeter (DVOM), measure the resistance
(ohmmeter function) between the sensor terminals. If the resistance is
190-250 ohms, the sensor is okay.
REMOVAL & INSTALLATION
Disconnect the negative battery cable.
Disconnect the three terminal connector from the vehicle speed
Remove the fasteners that secure the VSS to the transaxle housing
Remove the VSS.
Install the VSS.
Install the mounting bolts.
Connect the three terminal connector to the sensor.
hi, sounds like the vehicle speed sensor mounted on the transmission is going bad or loosing signal. generally, honda speedometers work for life, i've only ever replaced one. now, this is a split year so it may have just a cable going to the transmission instead of an electronic sensor. if the cable is loose, this may also cause this issue. you should probably have a professional shop take a look as the speedometer cable/sensor is very buried in the back of the engine compartment under the air intake hose and behind the starter. also, if there is a check engine light on when the speedo stops working, this should be an easy diagnostic for a technician to do, it would likely be the speed sensor causing this engine light.
Park your Honda
on a level surface, make sure the ignition is off, activate the
emergency brake and place blocks behind the back tires for safety.
Disconnect the negative battery cable with a terminal puller.
Raise the vehicle on the side of the wheel speed sensor's location.
Remove the wheel and tire assemblies.
Disconnect the sensor harness connector. At the connector end, remove the
grommets, clips or retainers in order to detach the harness. Take note
of where these connect in order to install the new sensor correctly.
Unscrew the speed sensor mounting bolt and remove the sensor from the vehicle.
Obtain the new speed sensor and install it in the differential housing, with the
retaining bolt loosely tightened.
Use the white line on the wires as a guide and route the wiring harness
without twists or crimps. Then torque the mounting bolt to 7.2 foot
pounds (9.8 Nm).
Start at the sensor end and, working your way to the connector end, attach
all the clips, retainers and grommets as observed during removal.
Connect the sensor wire.
Lower the vehicle safely and reconnect the negative battery cable. Refer
to your owner's manual to perform an ABS system check to confirm that
you installed the sensor properly.
