How does the speed sensor work on an Altima?
The vehicle speed sensor in your Altima provides a signal to the on-board computer that indicates actual vehicle speed from the output shaft of the transmission.
What are the symptoms of a bad transmission speed sensor?
Symptoms of a Bad or Failing Transmission Speed Sensor. 1 1. 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 2 2. Cruise Control Does Not Work. 3 3. Check Engine Light Comes On.
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,…
Can a bad speed sensor stop a car from starting?
A bad crankshaft or camshaft position sensor may prevent the car from starting. Some vehicles have redundant sensors that allow the vehicle to start and run even if one speed sensor is bad. In these cases, you are likely to see a check engine light with a code that should give you a clue which speed sensor is faulty.
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 check engine light be a bad speed sensor?
But if you have malfunctioning cruise control and a Check Engine light coming on, this is a clear indication of a faulty speed sensor. After all, the engine control unit depends on having valid speed information regarding the engine’s crankshaft.
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’s input shaft. The other sensor is the output shaft speed (OSS) sensor.
Where does the Nissan speed sensor come from?
Most Nissan Models 2012 + : The Engine Control Module (ECM) receives vehicle speed signals from two different paths via CAN communication line: One is from the Anti-lock Brake System (ABS) Actuator and Electric Unit (Control Unit) via the combination unit and the other is from Transmission Control Module (TCM). P0500 NISSAN More Information
Where does the speed sensor on Nissan p0500 come from?
The Engine Control Module ( ECM) receives vehicle speed signals from two different paths via CAN communication line: One is from the Anti-lock Brake System (ABS) Actuator and Electric Unit (Control Unit) via the combination unit and the other is from Transmission Control Module (TCM). Need more information on how to fix the P0500 NISSAN code?
How does the speed sensor on a Toyota work?
The vehicle speed sensor outputs a 4 pulse signal for every revolution of the rotor shaft, which is rotated by the transmission output shaft via the driven gear.
How do you install a sensor in a transmission?
Insert the new sensor into the transmission and push it down as you twist it until it seats completely in the transmission. Rotate the sensor to line up the mounting hole and install the 10 mm bolt. Tighten the bolt securely and plug the electrical connector into the new sensor.
What’s the engine code on a Nissan Altima?
Original engine code was p0175. Had mechanic replace 31935-1xf00 speed sensor assy. Problem was not corrected. Took to local dealer and was told needs new transmission control module unit $850 and new transmission $3,500.
Where is my vehicle speed sensor wire located for?
The other 2 are not used but the VSS wire is the brown wire located on the larger of the 2 connectors not being used. In addition to the standard power and ground leads, remote-mount navigation (and even some in-dash units) systems connect to a vehicle’s Vehicle Speed Sensor (VSS) wire.
Where is the speed sensor on a Nissan Altima?
The battery in the Nissan Altima is located on the driver-side of the engine compartment in front of the air filter housing. Remove the electrical connector from the speed sensor located on the driver-side of the transmission near the firewall.
