DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
PCM P0505:00 Idle Control System: No Sub Type Information Sets when the PCM detects the desired RPM could not be reached or controlled during the KOER self-test. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Diagnose other Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, inspect the intake air system for air restrictions, vacuum leaks, and damage. If no concerns are present, clear the DTC and carry out the KOER, self-test.
PCM P0506:00 Idle Control System - RPM Lower Than Expected: No Sub Type Information Sets when the PCM detects the engine idle speed is less than the desired RPM. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Diagnose other Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, inspect the intake air system for air restrictions, vacuum leaks, and damage. If no concerns are present, clear the DTC and carry out the KOER, self-test.
PCM P0507:00 Idle Control System - RPM Higher Than Expected: No Sub Type Information Sets when the PCM detects the engine idle speed is greater than the desired RPM. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Diagnose other Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, inspect the intake air system for air restrictions, vacuum leaks, and damage. If no concerns are present, clear the DTC and carry out the KOER, self-test.
PCM P050A:00 Cold Start Idle Control System Performance: No Sub Type Information Sets when the PCM detects the difference between desired and actual engine speed exceeds the calibrated threshold. 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 Diagnostic Trouble Codes (DTCs). Diagnose other Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, inspect the intake air system for air restrictions, vacuum leaks, and damage. If no concerns are present, clear the Diagnostic Trouble Codes (DTCs) and verify the engine coolant temperature is below 37.8°C (100°F). Allow the vehicle to soak for 2 to 3 hours if necessary for the engine coolant temperature 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 Diagnostic Trouble Codes (DTCs) are present and the MIL is not illuminated after idling for 6 minutes, carry out the KOER, self-test to confirm that no Diagnostic Trouble Codes (DTCs) are present and the repair is complete.
PCM P050B:00 Cold Start Ignition Timing Performance "A": No Sub Type Information Sets when the PCM detects the difference between desired and commanded spark timing exceeds the calibrated threshold. 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 Diagnostic Trouble Codes (DTCs). Diagnose other Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, inspect the intake air system for air restrictions, vacuum leaks, and damage. If no concerns are present, clear the Diagnostic Trouble Codes (DTCs) and verify the engine coolant temperature is below 37.8°C (100°F). Allow the vehicle to soak for 2 to 3 hours if necessary for the engine coolant temperature 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 Diagnostic Trouble Codes (DTCs) are present and the MIL is not illuminated after idling for 6 minutes, carry out the KOER, self-test to confirm that no Diagnostic Trouble Codes (DTCs) are present and the repair is complete.
PCM P050E:00 Cold Start Engine Exhaust Temperature Too Low: No Sub Type Information Sets when the PCM detects the catalyst temperature ratio exceeds the calibrated value and the MIL illuminates. The PCM calculates the actual catalyst warm up temperature during a cold start. The PCM then compares the actual catalyst temperature to the expected catalyst temperature model. The difference between the actual and expected temperatures is a ratio. This DTC sets when this ratio exceeds the calibrated value and the malfunction indicator lamp (MIL) illuminates. 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 Diagnostic Trouble Codes (DTCs). Diagnose other Diagnostic Trouble Codes (DTCs) first. If no other Diagnostic Trouble Codes (DTCs) are present, inspect the intake air system for air restrictions, vacuum leaks, and damage. If no concerns are present, clear the Diagnostic Trouble Codes (DTCs) and verify the engine coolant temperature is below 37.8°C (100°F). Allow the vehicle to soak for 2 to 3 hours if necessary for the engine coolant temperature 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 Diagnostic Trouble Codes (DTCs) are present and the MIL is not illuminated after idling for 6 minutes, carry out the KOER, self-test to confirm that no Diagnostic Trouble Codes (DTCs) are present and the repair is complete.
PCM P115E:00 Throttle Actuator Control Throttle Body Air Flow Trim at Max Limit: No Sub Type Information Sets when the PCM detects the maximum allowed compensation is reached and is no longer able to compensate for buildup. Install a new throttle body. Refer to the appropriate 303-04 section, Fuel Charging and Controls.
PCM P1548:00 Engine Air Filter Restriction: No Sub Type Information Sets when the PCM detects the airflow is out of range at various engine speeds and during WOT operation when compared to the calibrated value. If this DTC sets, inspect the intake air system and replace the air filter if no restrictions are found. Refer to the appropriate 303-12 section, Intake Air Distribution and Filtering for air filter replacement.
PCM P2004:00 Intake Manifold Runner Control Stuck Open (Bank 1): No Sub Type Information Sets when the PCM detects the IMRC is commanded closed and the IMRC bank 1 sensor indicates the IMRC is open. The IMRC bank 1 sensor value should change when the IMRC is commanded open or closed.
