When Monitored and Set Condition
- When Monitored: Engine running for at least 30 seconds and no fault in the throttle valve actuator.
- Set Condition: Low limit: The Manifold Absolute Pressure (MAP) Sensor reading is below a calculated value when the throttle valve angle is greater than 80° for approximately 5 seconds. High limit: The MAP Sensor reading is greater than a calculated value that is determined by engine speed and throttle valve angle for approximately 5 seconds.
