Tech Notes for P0500 1999 Ford F150

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) or anti-lock brake system (ABS) control module. 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

When is the Code Detected?

The almost 0 km/h (0 MPH) signal from vehicle speed sensor is sent to Engine Control Module (ECM) even when vehicle is being driven.

  • My 1999 F-250 is having the same problems as stated above, however my Ford dealer says they have to start by repairing the ignition switch(?). They have already replaced the speed sensor eight months ago and I feel this is their way of getting out of the warranty on this part. Is there any service bulletin on this problem?
