Pinpoint Test Kg: Fuel Injector
Normal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PCM P2149:00 | Fuel Injector Group "B" Supply Voltage Circuit/Open: No Sub Type Information | Sets when the PCM detects the injector relay voltage is less than the calibrated threshold. This DTC also sets when a concern is detected in the INJRLY circuit. |
| PCM P21CF:00 | Cylinder 1 Injector "B" Circuit/Open: No Sub Type Information | Sets when the PCM detects the fuel injector circuitry is inoperative. The CCM monitors the operation of the fuel injector drivers in the PCM. |
| PCM P21D0:00 | Cylinder 2 Injector "B" Circuit/Open: No Sub Type Information | Sets when the PCM detects the fuel injector circuitry is inoperative. The CCM monitors the operation of the fuel injector drivers in the PCM. |
| PCM P21D1:00 | Cylinder 3 Injector "B" Circuit/Open: No Sub Type Information | Sets when the PCM detects the fuel injector circuitry is inoperative. The CCM monitors the operation of the fuel injector drivers in the PCM. |
| PCM P21D2:00 | Cylinder 4 Injector "B" Circuit/Open: No Sub Type Information | Sets when the PCM detects the fuel injector circuitry is inoperative. The CCM monitors the operation of the fuel injector drivers in the PCM. |
| PCM P21D3:00 | Cylinder 5 Injector "B" Circuit/Open: No Sub Type Information | Sets when the PCM detects the fuel injector circuitry is inoperative. The CCM monitors the operation of the fuel injector drivers in the PCM. |
| PCM P21D4:00 | Cylinder 6 Injector "B" Circuit/Open: No Sub Type Information | Sets when the PCM detects the fuel injector circuitry is inoperative. The CCM monitors the operation of the fuel injector drivers in the PCM. |
| PCM P2C27:00 | Fuel Injector Group "B" Supply Sense Circuit Low: No Sub Type Information | Sets when the PCM detects the injector relay voltage is less than the calibrated threshold. This DTC also sets when a concern is detected in the injector relay (INJRLY) circuit or the injector power monitor (INJPWRM) circuit. |
| PCM P2C28:00 | Fuel Injector Group "B" Supply Sense Circuit High: No Sub Type Information | Sets when the PCM detects the INJRLY circuit voltage is more than the calibrated threshold. This DTC also sets when the injector power monitor (INJPWRM) circuit voltage is more than the calibrated threshold. |
