    Speedometer stopped woirking after attempting to engage the cruise control. After approximately 100 km of driving speedometer started working again.

    Service engine soon light also came on.

    Took vehicle to the shop and they said the code indicated a problem with the speed sensor.

    After doing a basic tune up with changed plugs all codes read normal.

    Several days later speedometer again stopped working. Then came back on and worked fine. Stopped again then worked fine.

    Have not returned it to shop yet but wonder if this sounds familiar to anyone for the 99 SE wagon??

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.

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.

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. .

Duag code u1262, p0500 & p0720


Your codes are as follows:

U1262 communications bus fault
P0500 Vehicle Speed Sensor Malfunction
P0720 Output Speed Sensor Circuit Malfunction

What, if any, symptoms is your vehicle showing?

If your Vehicle Spped Sensor has gone bad, it can cause loss of anti-lock brakes, "anti-lock" or "brake" warning lamps on the dash, the speedometer or odometer may not work properly (or at all), your vehicle's RPM limiter may be decreased or automatic transmission shifting to be erratic.
