Introduction

Normal Operation and Fault Conditions

Refer to the DTC Fault Trigger Conditions.

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
PCM P0111:00 Intake Air Temperature Sensor 1 Circuit Range/Performance (Bank 1): No Sub Type Information Sets when the PCM detects the IAT sensor value does not correlate with the ECT sensor value or the CHT sensor value at ignition ON after a calibrated soak period (typically 6 to 8 hours).
PCM P0112:00 Intake Air Temperature Sensor 1 Circuit Low (Bank 1): No Sub Type Information Sets when the PCM detects the IAT sensor signal is less than the self-test minimum. An IAT sensor PID reading less than the self-test minimum with ignition ON engine OFF or during any engine operating mode indicates a concern is present.
PCM P0113:00 Intake Air Temperature Sensor 1 Circuit High (Bank 1): No Sub Type Information Sets when the PCM detects the IAT sensor signal is greater than the self-test maximum. An IAT sensor PID reading greater than self-test maximum with the ignition ON engine OFF or during any engine operating mode indicates a concern is present.
PCM P0114:00 Intake Air Temperature Sensor 1 Intermittent/Erratic (Bank 1): No Sub Type Information Sets when the PCM detects the IAT sensor signal was intermittent during the Comprehensive Component Monitor (CCM). Monitor the IAT sensor value on a scan tool. Look for sudden changes in the reading when the harness is wiggled or the sensor is tapped.
PCM P1112:00 Intake Air Temperature Circuit Intermittent: No Sub Type Information Sets when the PCM detects the IAT sensor signal is intermittent. Monitor the IAT sensor PID on a scan tool. Look for sudden changes in the reading when the harness is wiggled or the sensor is tapped.

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 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.
