Discovery I (LJ) V8-4.0L (1996)

If the freeze frame data shows a road speed that does not conform to the engine speed (for example 110 mph at 2000 rpm or a road speed of 0 mph), an
intermittent fault with the VSS could be the problem.
If inconsistencies between engine speed and vehicle speed are observed, replace the sensor. See attached DTCR samples
14 CUX Vehicles 94-95 MY
These vehicles use the same VSS as GEMS equipped vehicles, but do not have OBDII capable diagnostics.
If the VSS on a 14 CUX vehicle suffers from an intermittent fault, the only symptoms experienced by the driver would be speedometer malfunctions,
surging/hesitation at highway speeds, or cruise control drop out. Misfire detection does not exist on these vehicles. therefore no misfire MIL's could be
flagged.
