The simpliest solution is to reset the code and see it clears. Depending on your model its on eithe rear axle or transmission.

I have a1999 cougar the speed on stop working now the transmission will not shift in less you manual shift your self what could be the problem


The speedometer stopped working ? is this what you meant ? You probably have a bad VSS - vehicle speed sensor . The VSS is an input to the PCM - engine computer , besides being a signal for the speedometer it is used for shift control and other thing's .
Vehicle Speed Sensor The vehicle speed sensor (VSS) (Figure 43) is a variable reluctance or Hall-effect sensor that generates a waveform with a frequency that is proportional to the speed of the vehicle. If the vehicle is moving at a relatively low velocity, the sensor produces a signal with a low frequency. As the vehicle velocity increases, the sensor generates a signal with a higher frequency. The PCM uses the frequency signal generated by the VSS (and other inputs) to control such parameters as fuel injection, ignition control, transmission/transaxle shift scheduling and torque converter clutch scheduling. You could possibly have a DTC stored in the PCM.
P0500 - Vehicle Speed Sensor (VSS) Malfunction Indicates the powertrain control module (PCM) detected an error in the vehicle speed information. Vehicle speed data is received from either the vehicle speed sensor (VSS), transfer case speed sensor (TCSS), anti-lock brake system (ABS) control module, generic electronic module (GEM), or central timer module (CTM). If the engine rpm is above the torque converter stall speed (automatic transmission) and engine load is high, it can be inferred that the vehicle must be moving. If there is insufficient vehicle speed data input, a malfunction is indicated and a DTC is set. On most vehicle applications the malfunction indicator lamp (MIL) will be triggered when this DTC is set.
  • Open in VSS+/VSS- harness circuit.
  • Open in TCSS signal or TCSS signal return harness circuit.
  • Short to GND in VSS harness circuit.
  • Short to GND in TCSS harness circuit.
  • Short to PWR in VSS harness circuit.
  • Short to PWR in TCSS harness circuit.
  • Open or short in the vehicle speed circuit(s) (VSC) between the PCM and appropriate control module.
  • Damaged VSS or TCSS.
  • Damaged wheel speed sensors.
  • Damaged wheel speed sensor harness circuits.
  • Damage in module(s) connected to VSC/VSS circuit.
  • Damage drive mechanism for VSS or TCSS.
Diagnostic Aids: - Monitor VSS PID while driving vehicle. This DTC is set when the PCM detects a sudden loss of VSS signal over a period of time. If vehicle speed data is lost, check source of where vehicle speed signal originates. Note TCSS does not have a PID, circuitry frequency must be checked for sudden loss of sensor signal. P0501 - Vehicle Speed Sensor (VSS) Range/ Performance Indicates the powertrain control module (PCM) detected an error in the vehicle speed information. This DTC is set the same way as P0500, however the malfunction indicator lamp (MIL) is not triggered.
  • Refer to possible causes for P0500.
Refer to diagnostic aids for P0500.

Have a hard fault code P0500


According to http://repairpal.com/OBD-II-Code-P0500:

Vehicle Speed Sensor Malfunction
Symptoms
  • Check Engine Light will illuminate
  • Vehicle may not shift properly
  • Speedometer may not operate correctly
  • In some cases, there are no adverse conditions noticed by the driver
  • In some cases, there may be performance problems and/or shifting problems.
  • Other warning lights may come on such as the ABS light and Traction Control light.
Common Problems That Trigger the P0500 Code
  • Defective Vehicle Speed Sensor
  • Defective Speedometer
  • Vehicle Speed Sensor wiring or connector
  • Communication (CAN) bus problems
  • Defective transmission or differential Vehicle Speed Sensor drive gear
Common Misdiagnoses
  • Speedomter problem
  • Internal Transmission problem
  • ABS/Traction Control probelm
  • Driveline problem

Where is p0500 located?


code p0500 refers to vehicle speed sensor(VSS) --circuit malfunction====causes--wiring-- VSS --ECM
The VSS is normally located in/at the rear of the gear box.

Car is cutting off while driving need to know if the codes that are showing is the reason my car is cutting off, p0500,p1131, p0174


P0500 stands for vehicle speed sensor malfunction
P0174 stands for System to lean (Bank 2) so you proably arent getting enough fuel or spark
P1131 = Insufficient Switching O2 Bank 1 Sensor 1 Sensor/Lean

I have a po 500 code that keep on coming up I have changed the vehicle speed sensor but it keep coming up on my ford f150 when the wiring was checked they found everything ok


P0500 - Vehicle Speed Sensor Malfunction
Basically this means that the vehicle's speed as read by the Vehicle Speed Sensor (VSS) is not working properly.

Symptoms of a P0500 DTC may include:
* loss of anti-lock brakes
* the "anti-lock" or "brake" warning lamps on the dash may be lit
* the speedometer or odometer may not work properly (or at all)
* your vehicle's RPM limiter may be decreased
* the shifting of an automatic transmission may become erratic
* other symptoms may also be present

Causes: A code P0500 may mean that one or more of the following has happened:
* The Vehicle Speed Sensor (VSS) is not reading (functioning) properly
* There is a broken/frayed wire leading to the vehicle speed sensor
* The vehicle's PCM is not correctly configured for the actual tire size on the vehicle

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back.

Next, check all wiring and connectors that lead to the speed sensor. The location of the sensor depends on your vehicle. The sensor could be on the rear axle, transmission, or perhaps the wheel hub (brake) assembly.

If the wiring and connectors are OK, then check the voltage at the speed sensor. Again, the exact procedure wil depend on your make and model of vehicle.

If everything looks OK, replace the sensor.

I hope helps; remember to rate and comment this.

The green overdrive light on the dash keeps flashing and the transmission jerks into gear. Any suggestions on how to solve this. The test codes that come are P1747, PO156, and PO161. I have already...


not an oxygen sensor



vehicle speed sensor or oss is most likely cause.


Output Shaft Speed Sensor (OSS) 7H103: The output shaft speed (OSS) sensor is a magnetic pickup, located at the output shaft ring gear that sends a signal to the powertrain control module to indicate transmission output shaft speed. The powertrain control module uses this signal for torque converter clutch control, shift scheduling, used in determining EPC pressure. Symptoms: No converter engagements, harsh shifts, abnormal shift schedules. DTC: P0720, P0721 std~us~en~file=d14110a.gif~gen~ref.gif


Vehicle Speed Sensor (VSS) 9E731: The vehicle speed sensor is a magnetic pickup that sends a signal to the powertrain control module. This VSS signal tells the PCM vehicle speed. The PCM uses this signal to modify upshift schedules. Symptoms: Shift engagement/disengagement (hunting) on grades. DTC: P0500, P0503, P1500, P1501, P1503

They are not the sensors you want. The car uses the abs wheel sensors for vehicle speed. Your problem lies in the abs system , possibly the left front sensor, abs ecu or speedo cluster, Clear the code and see if it stay out otherwise you'll need to go to a trusted technician. .
