How does the VSS work on a Ford F350?
How does the VSS work on a Ford F350?
P0500 is a OBDII trouble code that affects the Ford F350 ‘s Vehicle Speed Sensor (VSS). The VSS sends a signal to the engine’s computer letting it know how fast that the vehicle is going. The F350 uses this signal for many vehicle functions.
What happens when the VSS does not work?
Speedometer Failure – Without a properly working vehicles speed sensor, the speedometer will not register any speed. It’ll just sit at 0 MPH while you are driving. The Odometer may not work at all. Cruise Control Failure – When a vehicle is not getting a signal from the VSS, it’ll not let the cruise control engage.
Where does VSS data go in a car?
This information is sent to the electronic computer module (ECM), where it is shared with other vehicle systems that depend on this data. The function of several of your vehicle’s systems depend on data from the VSS and ECM, such as variable speed power steering, cruise control, anti-lock brakes and your speedometer.
What are the functions of the VSS and ECM?
The function of several of your vehicle’s systems depend on data from the VSS and ECM, such as variable speed power steering, cruise control, anti-lock brakes and your speedometer. To correct your VSS-related problem, know where it is located and how to replace it.
Is the OSS sensor inline with the TFT sensor?
Check for power going into the sensor, and at the PCM harness connector using a factory wiring diagram as reference. If the OSS sensor is inline with the TFT sensor, the voltage will vary based on the temperature of the transmission fluid.
What happens when the OSS sensor is malfunctioned?
The Powertrain control module / Engine control module (PCM/ECM) has determined there is a malfunction with the OSS sensor. The PCM/ECM may substitute values based on other sensors to determine shift timing, torque converter operation and EPC pressure if the OSS sensor information is unavailable.
Can a transmission fluid temperature ( OSS ) sensor malfunction?
Note: On some vehicles, the OSS sensor is inline with the Transmission Fluid Temperature (TFT) sensor, if there is a failure with the TFT sensor or associated wiring, the OSS sensor may malfunction as well.
How is the VSS sensor used in the PCM?
OPERATION The Vehicle Speed (VSS) Sensor input is used by the PCM to determine vehicle speed. The VSS generates a signal that increases in frequency proportionate to vehicle speed. The PCM has a base frequency stored in memory for a distance of one mile.
How does the vehicle speed sensor ( VSS ) work?
The Vehicle Speed Sensor (VSS) is a magnetic pick-up that sends a signal to the Powertrain Control Module (PCM). VSS – Vehicle Speed Sensor Vehicle Speed Sensor (VSS) OPERATION The Vehicle Speed (VSS) Sensor input is used by the PCM to determine vehicle speed. The VSS generates a signal that increases in frequency proportionate to vehicle speed.
Which is the Transmission Control Module fault code?
Transmission Control Module or TCM: Transmission OBD2 code P0613 4.3 #3. Engine Control Module (ECM/TCM) Incompatible: Fault code P0614 4.4 #4. Transmission Control Module Malfunction: Error Code P0700 4.5 #5. Transmission Range Sensor Circuit Performance: OBD2 Code P0706
How to test the resistance of the VSS sensor?
1 Turn the ignition switch to the OFF position. 2 Disengage the wiring harness connector from the VSS. 3 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.
Where is the speed sensor on a Ford PowerStroke?
There are three speed sensors on an ’06, one on the rear diff, and one on each front hub. VSS Ford pt# is F85Z-2L373-AB. Refer to pinpoint test G, (Inaccurate Speedometer Indication) section in the workshop manuals.
What are the functions of a Ford F350?
The F350 uses this signal for many vehicle functions. It helps control transmission shifts, ABS, cruise control, the speedometer, and more. Fixing it should be considered a priority. Symptoms will vary depending on the model year and other conditions. But, these are the most common symptoms of P0500 in general.
Where is the VSS-vehicle speed sensor located?
The VSS-vehicle speed sensor is located in the rear axle of the truck. Look for a wire harness that runs to the top of the rear diff.

How does the speedometer work on a Ford F350?
A modern vehicle’s speedometer takes the input from the Vehicle Speed Sensor and sends that data to the ECU. The ECU is programmed with your F350’s gear ratios and stock tire height. It combines this data to send the speed reading to the instrument cluster.
