Wide-Open-Throttle Mode
WARNING: This page is about a different car, the 2012 Jeep Patriot and 2012 Jeep Compass. 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 APPS 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.
