DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PCM P0068:00 | MAP / MAF - Throttle Position Correlation: No Sub Type Information | Sets during KOER self-test the when the PCM detects a comparison of the readings are not consistent with the calibrated load values. An intake air system leak at a hose, line or connection of any intake air system or PCV system component may cause this DTC to set. The PCM monitors a vehicle operation rationality check by comparing the TP sensor to the MAF sensor readings (if equipped) or to the MAP sensor readings (if equipped). Check for other Diagnostic Trouble Codes (DTCs). Diagnose all other Diagnostic Trouble Codes (DTCs) first. |
| PCM P0120:00 | Throttle/Pedal Position Sensor/Switch "A" Circuit: No Sub Type Information | Sets when the PCM detects a concern with the TP signal. This concern exhibits a symptom of limited power. |

This concern exhibits a symptom of limited power. A TP1 PID reading less than 0.25 volt in ignition ON, engine OFF or ignition ON, engine running indicates a concern is present. |
| PCM P0123:00 | Throttle/Pedal Position Sensor/Switch "A" Circuit High: No Sub Type Information | Sets when the PCM detects the TP1 signal is too high. This concern exhibits a symptom of limited power. A TP1 PID reading greater than 4.75 volts in ignition ON, engine OFF or ignition ON, engine running indicates a concern is present. |
| PCM P0124:00 | Throttle/Pedal Position Sensor/Switch "A" Intermittent: No Sub Type Information | Sets when the PCM detects the TP circuit is intermittently open or shorted. This concern exhibits a symptom of limited power. |
| PCM P0221:00 | Throttle/Pedal Position Sensor/Switch "B" Circuit Range/Performance: No Sub Type Information | Sets when the PCM detects the PCM indicates the TP sensor 2 circuit is out of range in either the closed or WOT modes. This concern exhibits a symptom of limited power. |
| PCM P0222:00 | Throttle/Pedal Position Sensor/Switch "B" Circuit Low: No Sub Type Information | Sets when the PCM detects the TP2 signal is too low. This concern exhibits a symptom of limited power. A TP2 PID reading less than 0.25 volt in ignition ON, engine OFF or ignition ON, engine running indicates a concern is present. |
| PCM P0223:00 | Throttle/Pedal Position Sensor/Switch "B" Circuit High: No Sub Type Information | Sets when the PCM detects the TP sensor signal is too high. This concern exhibits a symptom of limited power. A TP2 PID reading greater than 4.75 volts in ignition ON, engine OFF or ignition ON, engine running indicates a concern is present. |
| PCM P1124:00 | Throttle Position Sensor "A" Out Of Self Test Range: No Sub Type Information | Sets when the PCM detects the TP1 or TP2 is greater than the expected value. During key KOEO and KOER self-tests, the PCM monitors the TP sensor inputs to determine if the TP1 and TP2 signals are less than an expected value. Repeat the self-test without applying the accelerator pedal. Make sure the floor mat is not interfering with the accelerator pedal. Diagnose any TP circuit Diagnostic Trouble Codes (DTCs) first. |
| PCM P1584:00 | Throttle Control Detected ETB Malfunction: No Sub Type Information | Sets when the PCM detects the electronic throttle body (ETB) fails the self-test. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Diagnose other Diagnostic Trouble Codes (DTCs) first. |
| PCM P1588:00 | Throttle Control Detected Loss Of Return Spring: No Sub Type Information | Sets when the PCM detects the throttle does not return to the default (limp home) position. Visually inspect the throttle plate for an obstruction. |
| PCM P2100:00 | Throttle Actuator "A" Control Motor Circuit /Open: No Sub Type Information | This DTC sets when a PCM fault flag is set indicating the motor circuit is open. |
| PCM P2101:00 | Throttle Actuator "A" Control Motor Circuit Range/Performance: No Sub Type Information | Sets when the PCM detects a PCM fault flag is set indicating the motor circuit is open. |
| PCM P2107:00 | Throttle Actuator "A" Control Module Processor: No Sub Type Information | Sets when the PCM detects the electronic throttle control area of the PCM failed the self-test. The concern could be the result of an incorrect throttle position command, or TAC motor wires shorted together. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Diagnose other Diagnostic Trouble Codes (DTCs) first. |
| PCM P2109:00 | Throttle / Pedal Position Sensor "A" Minimum Stop Performance: No Sub Type Information | Sets when the PCM detects the throttle plate does not reach the lower mechanical stop position within a calibrated amount of time. Visually inspect the throttle plate for an obstruction. |
| PCM P2111:00 | Throttle Actuator "A" Control System - Stuck Open: No Sub Type Information | Sets when the PCM detects the PCM fault status indicates the throttle plate is at a greater angle than commanded. |
| PCM P2112:00 | Throttle Actuator "A" Control System - Stuck Closed: No Sub Type Information | Sets when the PCM detects the fault status indicates the throttle plate is at a lower angle than commanded. |
| PCM P2118:00 | Throttle Actuator "A" Control Motor Current Range/Performance: No Sub Type Information | Sets when the PCM detects a concern with the electronic throttle body TACM circuits. Do not install a new electronic throttle body (ETB) for this DTC. Check for circuit related Diagnostic Trouble Codes (DTCs). Check for intermittent TACM+ circuit and TACM- circuit shorted to ground. |
| PCM P2119:00 | Throttle Actuator "A" Control Throttle Body Range/Performance: No Sub Type Information | Sets when the PCM detects the throttle plate is at an angle other than commanded. |

| PCM P2163:00 | Throttle/Pedal Position Sensor "A" Maximum Stop Performance: No Sub Type Information | Sets when the PCM detects the throttle plate does not reach the upper mechanical stop position within a calibrated amount of time. Visually inspect the throttle plate for an obstruction. |
| PCM P2176:00 | Throttle Actuator "A" Control System - Idle Position Not Learned: No Sub Type Information | Sets when the PCM detects the PCM is unable to learn the calibrated throttle positions. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). Diagnose other Diagnostic Trouble Codes (DTCs) first. |
