DTC P1294: Target Idle Not Reached: Description

Engine speed is monitored with engine idling, transmission in Drive, and no Manifold Absolute Pressure (MAP) sensor or Throttle Position (TP) sensor DTCs present. DTC will set in Powertrain Control Module (PCM) memory when PCM senses engine idle speed is at least 200 RPM more or 100 RPM less than target idle speed for 14 seconds. One bad trip is required to set DTC. Possible causes are: defective Idle Air Control (IAC) motor, IAC driver circuit open, vacuum leaks, air intake system leaks or restrictions, defective throttle body or linkage improperly positioned or defective PCM.
