Displacement on Demand (DoD) Inhibit Reasons
Listed below are the powertrain conditions that will inhibit V4 mode, while operating under light load driving conditions:
? Engine manifold vacuum low
?
Brake booster vacuum pressure low
? Accelerator pedal position rate of increase too high, electronic throttle control
? Accelerator pedal position too high, electronic throttle control
[and so on, loong list]
? Fault Active or Fault Pending--displacement on demand (DoD) is disabled for the following faults:
- Manifold Absolute Pressure Sensor
-
Brake Booster Vacuum Sensor
- Engine Oil Pressure Sensor
- Engine Coolant Temperature Sensor
- Vehicle Speed Sensor
- Crankshaft Position Sensor
- Engine Misfire Detected
- Displacement On Demand Solenoid Driver Circuit
