Low Idle Airflow Monitor - Systems With Electronic Throttle Control
When the CSER strategy is enabled, the Electronic Throttle Control system will request a higher idle rpm, elevating engine airflow. Vehicles that have ETC and do not have a separate airflow test (P050A). Any fault that would not allow the engine to operate at the desired idle rpm during a cold start would be flagged by one of three ETC DTCs:
- P2111 (throttle actuator control system stuck open),
- P2112 throttle actuator control system stuck closed)
- P2107 (throttle actuator control module processor/circuit test).
All three DTCs will illuminate the MIL in 2 driving cycles, and immediately illuminate the "ETC" light. These DTCS are also documented in the ETC section of this document.
For the 2009 MY, only the Fusion/Milan utilizes the CSER Component monitor with ETC.
THROTTLE PLATE CONTROLLER AND ACTUATOR OPERATION
| DTCs | P2107 - processor test (MIL) P2111 - throttle actuator system stuck open (MIL) P2112 - throttle actuator system stuck closed (MIL)
NOTE:
For all the above DTCs, in addition to the MIL, the ETC light will be on for the fault that caused the FMEM action.

| Monitor execution | Continuous |
| Monitor Sequence | None |
| Monitoring Duration | 60 msec for processor fault, 500 msec for stuck open/closed fault |
THROTTLE PLATE CONTROLLER AND ACTUATOR MALFUNCTION THRESHOLDS
| P2111 - Desired throttle angle vs. actual throttle angle > 6 degrees P2112 - Desired throttle angle vs. actual throttle angle < 6 degrees P2107 - Internal processor fault, lost communication with main CPU |
