Where is the engine input speed sensor located?
The typical engine input speed sensor circuit is centered around a stationary mounted electromagnetic hall-effect sensor which is mounted in such a manner as to allow a toothed reluctor ring to pass in very close proximity to its magnetic tip. The reluctor ring is attached to the input shaft of the transmission.
Why is my engine speed sensor not working?
This type of code may be caused by either a mechanical problem or an electrical problem. Inserted through the transmission case, near the front of the input shaft, the engine speed input sensor is usually fitted with a rubber O-ring on the sensor housing so that it makes a seal with the transmission case.
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 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.

What does ECM do on Nissan p0726?
The Engine Control Module ( ECM) monitors the engine speed through the Crankshaft Position ( CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM). Need more information on how to fix the P0726 NISSAN code?
What happens when a cruise control sensor fails?
When the sensors fail to deliver accurate data to the onboard computer on your car, truck, or SUV, the powertrain control module (PCM) will send an error code to the vehicle’s ECU. As a safety precaution, the ECU will shut down the cruise control and render it inactive.
Also referred to as the transmission input speed sensor, or input speed sensor, the engine speed input sensor, this component could experience a malfunction caused by either a mechanical or electrical problem. The engine speed input speed sensor is generally inserted through the transmission case, near the front of the input shaft.
What happens if the input speed sensor fails?
If the input speed sensor fails, it means your car does not know how fast it is moving, which can cause many systems to fail. The symptoms can include: You can probably tell that all of these symptoms can be dangerous.
What to do if your car speed sensor is not working?
Connect a scan tool under the dash and scroll through the live data until you find the VSS PID. Monitor the VSS while driving and see if it corresponds to how fast you are driving. If the reading doesn’t match your actual speed, something is wrong with the sensor or its circuit.
What does it mean when your speed sensor says p0500?
If the reading does match but you still have a P0500 code, you likely have an intermittent problem. If your vehicle fails the test listed above, it’s time to determine what part of the VSS circuit is to blame. Testing the sensor varies slightly, depending on which type of sensor your vehicle uses.
What causes the engine speed input sensor to malfunction?
The engine speed input sensor is sometimes called the transmission input speed sensor and the input speed sensor. This type of code may be caused by a mechanical problem or an electrical problem.
What does p0725 mean on an engine speed sensor?
The presence of a stored code P0725 means that the powertrain control module (PCM) has detected a circuit malfunction with the engine speed sensor input signal. The engine speed input sensor is sometimes called the transmission input speed sensor and the input speed sensor.
What is the diagnostic code for engine speed?
P0725 is a diagnostic trouble code (DTC) for “Engine Speed Input Circuit 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.
What are the engine speed input circuit codes?
Related engine speed input circuit engine codes include: P0726 Engine Speed Input Circuit Range/Performance P0727 Engine Speed Input Circuit No Signal P0728 Engine Speed Input Circuit Intermittent A stored code P0725 should be considered severe as the conditions which have caused it to be stored may result in damage to the transmission.
