Wide Open Throttle Mode
2016 Dodge and Ram Charger R/TSECTION Wide Open Throttle Mode
This is an Open Loop mode. During wide open throttle operation, the PCM receives the following inputs.
- Battery voltage
- Crankshaft Position (CKP) sensor
- Engine Coolant Temperature (ECT) sensor
- Intake Manifold Air Temperature (MAT) sensor
- Manifold absolute pressure (MAP) sensor
- Accelerator Pedal Position Sensor (APPS)
- Throttle position sensors (TPS)
- Camshaft Position Sensor (CPS) signal
During wide open throttle conditions, the following occurs:
- Voltage is applied to the fuel injectors with the ASD relay via the PCM. The PCM will then control the injection sequence and injector pulse width by turning the ground circuit to each individual injector on and off. The PCM ignores the oxygen sensor input signal and provides a predetermined amount of additional fuel. This is done by adjusting injector pulse width.
- The PCM adjusts ignition timing by turning the ground path to the coil on and off.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
