P050A - COLD START IDLE AIR CONTROL PERFORMANCE
| Description: | The monitor compares the actual measured engine speed to the engine speed requested by the powertrain control module (PCM). When the difference between desired and actual engine speed exceeds the calibrated threshold, the DTC sets. | ||
| Possible Causes: |
|

| Diagnostic Aids: | Disregard the freeze frame data. Freeze frame data does not apply to the cold start monitor. This DTC is informational only and may be accompanied by other DTCs. Diagnose other DTCs first. If no other DTCs are present, inspect the intake air system for air restrictions, vacuum leaks, and damage. If no concerns are present, clear the DTCs and verify the engine coolant temperature (ECT) is below 37.8°C (100°F). Allow the vehicle to soak for 2-3 hours if necessary for the ECT to fall below 37.8°C (100°F). Start the engine without touching the accelerator pedal and allow the engine to idle for 6 minutes in park. If no DTCs are present and the malfunction indicator lamp (MIL) is not illuminated after idling for 6 minutes, carry out the key ON engine running (KOER) self-test to confirm that no DTCs are present and the repair is complete. |
