Many Ford drivers may be familiar with the dreaded code P1500, which is a Vehicle Speed Sensor (VSS) code. This code can interfere with other on board diagnostic tests, such as the catalyst efficiency monitor, the EVAP monitor, or the HO2S monitor. The code is triggered when the VSS input signal is intermittent. Possible causes for this code include intermittent VSS connections, VSS harness circuits that are intermittent open or short, and a damaged VSS. Diagnosis of the code involves checking the wiring, connector, and sensor for damage. There are also several related service bulletins that can aid in troubleshooting and repairing the code, such as 16N02-S1, 19N01-S4, 19N05, 19S07-S2, and 19S19.
