Wide Open Throttle Mode

This is an OPEN LOOP mode. During Wide Open Throttle operation, the following inputs are used by the PCM:

• Inlet/Intake Air Temperature
• Engine Coolant Temperature
• Engine Speed
• Knock Sensor
• Manifold Absolute Pressure
• Throttle Position

When the PCM senses a Wide Open Throttle condition through the (TP) sensor it de-energizes the A/C compressor clutch relay. This disables the air conditioning system and disables EGR (if equipped).

The PCM adjusts injector pulse width to supply a predetermined amount of additional fuel, based on MAP and RPM.
