Glossary
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 typically delivers extra fuel to
the engine and de-energizs the A/C compressor at this time for acceleration
purposes. The PCM uses a switch or the TPS to identify the WOT condition.
