Wide-Open-Throttle Mode
WARNING: This page is about a different car, the 2012 Dodge Charger. However, it is still accessible from the selected car via links, so may be relevant.
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 Throttle Position Sensor (TPS) 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.
