What does the transmission input speed sensor do?
The Transmission Input Speed Sensor This sensor measures the revolutions per minute or RPMs of the input shaft. As the Torque convertor sends the proper pressure to the clutches and planetary gear assembly the car begins to move. When the car or truck is moving, the transmission input shaft rotates at the same RPM as the engine.
What does the Transmission Control Module processor do?
The TCM transmission module processor helps understand various signals transmitted by the drivetrain’s engine control module (ECM), and outputs signals to control a vehicle’s speed, shifting, and regulate the temperature inside the transmission.
What happens when a transmission sensor goes bad?
This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing, extending the interval between transmission shifts. An automatic transmission is hydraulically controlled and designed to shift smoothly.
Where is the speed sensor located on a car?
The transmission speed sensor is also a vital component in electronic speedometers. It is located either on the transmission output shaft, or the crankshaft, and cars tend to have two of them, so their data can be corroborated. The sensors function through a surprisingly simple mechanism.
What kind of speed sensor does a Honda Accord have?
We offer a full selection of genuine Honda Accord Speed Sensors, engineered specifically to restore factory performance. Please narrow the Speed Control Sensor results by selecting the vehicle.
What is the name of the transmission speed sensor?
There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’ input shaft. The other sensor is the output shaft speed (OSS) sensor.

Can a bad speed sensor cause a shift?
Harsh or improper shifting Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal.
Which is the output shaft speed ( OSS ) sensor?
The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’ input shaft. The other sensor is the output shaft speed (OSS) sensor.
What to do if your transmission speed sensor is bad?
Once the problem has been fixed, the mechanic will reset the error codes. If the problem rests with the speed sensors, depending on your particular transmission, the professional ASE certified mechanics may be able to replace the sensor.
Can a bad speed sensor affect shift timing?
Harsh or improper shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing,…
What does a bad speed sensor do?
A bad speed sensor most often affects the shifting of the automatic transmission. However, in cars with an onboard computer, the sensor also affects the ABS system , speedometer, cruise control and power steering. Proper diagnosis and repair is essential for safe operation of the car.
Where is the output shaft speed sensor located?
The output shaft speed sensor is located on the left rear of the transmission, the circuit runs from the sensor to the PCM.
What is a transmission input speed sensor?
Transmission Input Speed Sensor. The input speed sensor measures the RPM of the input shaft of the transmission. With the engine running and the vehicle in gear (forward or reverse), if the car or truck is not moving, the input shaft of the transmission is also not moving.
How does a speed sensor work?
Speed sensors convert the pulses created by the contact between the magnet and sensor ring through a coil attached to the sensor. This voltage is passed along to the controller. The controller counts the number of pulses to determine wheel speed and evaluates whether the ABS system should intercede to control braking.
