What does output speed sensor malfunction code mean?
It means that the powertrain control module (or transmission control module) perceives a problem with the output speed sensor (OSS) or its circuit. The sensor in question is the one responsible for the display of real-time vehicle speed. The powertrain control module (PCM) receives input from multiple sensors.
Why is there an error code on my transmission?
This code could indicate corrosion or other problems in the transmission range sensor. Your automatic transmission uses input and output speed sensors to determine whether your transmission is in the gear that the transmission control module (TCM) wants it to be in.
What is the OBD code for transmission output speed?
Some of the more common code responses associated with Transmission Output Speed Sensor issues are codes P0720, P0721, P0722 and P0723 based on the specific malfunction that alerts the PCM to set the code and activate the Check Engine Light.
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.
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.
Where is the input shaft speed sensor located?
The input shaft speed sensor is located on the side of the transmission by where the engine “inputs” power to the transmission (via torque converter), thus rotating the input shaft.
What is the output shaft speed sensor?
On electronically controlled transmissions, the Output Shaft Speed Sensor (OSS) is located on the end of the transmission before the drive axles or driveshaft to read the speed of the output shaft which may be used to determine shift scheduling, torque converter engagement schedule and Electronic Pressure Control (EPC) inside the transmission.
What is the Trans code on a check?
It is a nine-digit code that is used in the US. You will probably recognize it from the bottom of your checks. The transit number is also called the ABA RTN number, or the ABA routing transit number. It is used to identify the bank or institution from which it was drawn.
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.
Which is the first sensor on the transmission shaft?
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.
What is the VSS code for a speed sensor?
A typical VSS or vehicle speed sensor: P0500 Vehicle Speed Sensor “A” Malfunction P0502 Vehicle Speed Sensor “A” Low Input P0503 Vehicle Speed Sensor “A” Intermittent/Erratic/High This code is different from the P0500 code in the fact that it may not trigger the malfunction indicator light (MIL).
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.

What are the two sensors that monitor transmission speed?
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. If either of these two sensors falls out of alignment or experiences electrical issues, it impacts the operation of the entire transmission.
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,…
Why is the odometer and Speedo not working?
Neither the Speedo, odometer, nor cruise controls are working. I changed out the inst. cluster and the vss. It does not have a mechanical speed sensor, electric magnetic. I originally thought it was the cluster so I changed that, no good. A few weeks later the service engine light came on, checked for codes and got 24. I than changed the vss.
Where is the output speed sensor p0720 located?
You’ll commonly see this sensor mounted near the output shaft on the transmission. The P0720 code is activated when the PCM detects insufficient input from the OSS. This code is similar to P0721, P0722, and P0723. P0720 is a common issue among the following makes: Ford (especially a Ford F-150), Nissan, Dodge, BMW, and Honda.
What does p0722 mean on an OSS sensor?
NOTE: Note that code P0722 indicates a condition where the output shaft speed sensor is either not producing a signal, or if it does, the signal does not reach the PCM.

Is it possible to operate a car without a speed sensor?
While it’s technically possible to operate your vehicle without a properly functioning vehicle speed sensor, it is strongly discouraged. A faulty VSS can negatively impact multiple aspects of vehicle operation—which is why it’s best to replace a bad speed sensor as soon as possible.
Where is the speed sensor on a car?
The vehicle speed sensor (VSS) is also commonly referred to as a transmission speed sensor or output shaft speed sensor. It is a small device—typically mounted somewhere on the transmission—that determines how fast your vehicle is going by measuring the rotation of a toothed wheel on a shaft inside the transmission.
What is the diagnostic code for speed sensor malfunction?
P0500 is a diagnostic trouble code (DTC) for “Vehicle Speed Sensor Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $0.0 .
What are the symptoms of a bad camshaft position sensor?
Symptoms of a Bad or Failing Camshaft Position Sensor. $79.99 – $89.99. Average rating from 4,829 customers who received a Check Engine Light is on Inspection. The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM).
Can a bad MAP sensor cause engine failure?
MAP sensor on footwell inside engine compartment. A bad manifold absolute pressure (MAP) sensor can upset fuel delivery and ignition timing. Depending on your vehicle model, your engine might experience one or more of these performance problems: However, these symptoms are not exclusively symptoms of a failed MAP sensor.
