Question about 1999 Mercury Sable
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.
Hope this helps (remember to rate this answer).

Look for a sticker on your trunk hinge but dont worry if its not there. I think that some Ford products had it in the dash compartment. Dont worry we will stay after it till we get it. Check out this site.

Barring any vacuum leaks, P0401 is indicative of a bad EGR valve. Hope this answers your question. Best of luck.

Testimonial: "seems like it should not be as hard as you say "
That code is: Fuel Pump Primary Circuit Malfunction. Could it be the wires are not on tight or one is shorted? Check wiring very carefully.
