Location of the speed sensors on my 1999 ford explorer


Vehicle Speed Signal
The vehicle speed signal is generated by the rear anti-lock brake sensor and sent to the 4-wheel anti-lock brake system (4WABS) module. The 4WABS module sends the vehicle speed signal via circuit 679 (GY/BK) to all systems which require a vehicle speed signal input.
Speedometer
The electronic speedometer receives a speed signal from the 4WABS module.

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.

Wat is DTC PO500


Hi there:
DTC 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

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.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day

Code u1120 and code 0501


U1120 means the PCM doesn't receive a vehicle speed signal from the Anti-lock brake Module over the CAN C bus. This can be caused by the ABS module, PCM or something wrong with the can bus. This might be just an erroneous code and may never set again

Code P0501 Vehicle Speed Sensor Range/Performance
What does that mean? Basically this means that the vehicle's speed as read by the Vehicle Speed Sensor (VSS) is not working properly.
Potential Symptoms This code is different from the P0500 code in the fact that it may not trigger the malfunction indicator light (MIL). Potential symptoms are basically the same as the P0500 VSS code:

  • 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 P0501 DTC trouble code may be caused by one or more of the following:
  • 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 will depend on your make and model of vehicle.
If everything looks OK, replace the sensor.
