I could not find the error code P114C in the service manual, but I did find the other codes and their possible causes. Good luck.
P0219 - Engine Overspeed Condition
Description: This DTC sets when the vehicle has been operated in a manner which caused the engine speed to exceed a calibrated limit. The engine RPM is continuously monitored and evaluated by the PCM. This DTC sets when the RPM exceeds the calibrated limit set within the PCM.
For additional information on the engine RPM limiter, refer to Section 1, Powertrain Control Software .
Possible Causes: Wheel slippage (water, ice, mud, and snow)
Excessive engine RPM in NEUTRAL or operated in the incorrect transmission gear
High engine RPM with engine temperature within a calibrated limit of an overheating condition (GTDI engine)
Diagnostic Aids: This DTC may be accompanied by other DTCs. If DTC P1285 or P1299 is present, disregard DTC P0219 at this time. Diagnose DTC P1285 or P1299 first.
P0454 - EVAP System Pressure Sensor / Switch A Circuit Intermittent
Description: This DTC sets when the fuel tank pressure changes greater than 14 inches of water in 0.10 seconds.
Possible Causes: FTP circuit intermittent open
FTP circuit intermittent short
FTP sensor intermittent open
FTP sensor intermittent short
Contaminated FTP sensor
Damaged FTP sensor
P2112 - Throttle Actuator A Control System - Stuck Closed
Description: This DTC sets when the fault status indicates the throttle plate is at a lower angle than commanded.
Possible Causes: Throttle body stuck closed
Throttle body stuck binding
TACM+ circuit open
TACM- circuit open
TACM+ and TACM- circuits are cross wired
TACM+ and TACM- circuits are shorted together
Damaged PCM
P2282 - Air Leak Between Throttle Body And Intake Valve
Description: This DTC sets when the PCM detects an air leak that exceeds a calibrated limit for greater than 5 seconds. If the airflow entering the engine exceeds the airflow through the throttle, a leak is detected and this diagnostic fails.
Possible Causes: Unmetered air leaks between throttle body and intake valves
Air leaks at the intake manifold
Positive crankcase ventilation (PCV) system is leaking
