VSS:
Vehicle Speed Sensor. Sends a frequency signal to the PCM. The frequency
increases as the vehicle moves faster to give the PCM vehicle speed
information used to determine shift points, engine load, and cruise control
functions.
VTD:
Vehicle Theft Deterrent
Warmup Cycle:
Warmup cycle is when the engine coolant temperature rises at least 40 degrees
above that at engine start up.
WOT:
WideOpen Throttle. The vehicle operating condition brought about when the
throttle is completely (or nearly) open. The PCM typically delivers extra fuel to
the engine and deenergizes the A/C compressor at this time for acceleration
purposes. The PCM uses a switch or the TPS to identify the WOT condition.
