Warm-up Cycle:
Warm-up cycle is when the engine coolant temperature rises at least 40 degrees
above that at engine start up.
WOT:
Wide-Open Throttle. The vehicle operating condition brought about when the
throttle is completely (or nearly) open. The PCM will typically deliver extra fuel
to the engine and de-energize the A/C compressor at this time for acceleration
purposes. The PCM uses a switch or the Throttle Position Sensor to identify the
WOT condition.
