ALTERNATIVE FUELS DIAGNOSTIC TROUBLE CODE (DTC) DESCRIPTIONS
| DTC | Description | Possible Causes | Diagnostic Aids |
|---|---|---|---|
| P0182 - Fuel Rail Temperature (FRT) Sensor (A) Circuit Low Input P0183 - Fuel Rail Temperature (FRT) Sensor (A) Circuit High Input |
The alternative fuel control module (AFCM) monitors the fuel rail temperature (FRT) sensor. A fault is set when the AFCM receives an FRT sensor signal less than -62°C (-79 °F) or a signal greater than 127°C (260°F). |
|
The FRTMPAB PID will display a default value of 57°C (135°F) when the FRT is continually shorted regardless of fuel flow or temperature. Place the key in the off position for five seconds; the actual temperature should be reflected (before FMEM substitution). |
| P0192 - Fuel Rail Pressure (FRP) Sensor Low Input P0193 - Fuel Rail Pressure (FRP) Sensor High Input |
The alternative fuel control module (AFCM) monitors the fuel rail pressure (FRP) sensor. A fault is set when the AFCM receives an excessively high or low pressure reading. (Greater than 1034 kPa [150 psi] or less than 345 kPa [50 psi]). |
|
The FRPREAB PID will display the fuel rail pressure input to the AFCM. |
| P0201 - Injector Circuit/Open - Cylinder 1 P0202 - Injector Circuit/Open - Cylinder 2 P0203 - Injector Circuit/Open - Cylinder 3 P0204 - Injector Circuit/Open - Cylinder 4 P0205 - Injector Circuit/Open - Cylinder 5 P0206 - Injector Circuit/Open - Cylinder 6 P0207 - Injector Circuit/Open - Cylinder 7 P0208 - Injector Circuit/Open - Cylinder 8 |
The powertrain control module (PCM) monitors the injector driver outputs. A fault is set when the PCM detects an electrical load failure on the output circuit. |
|
The injector driver fault PID INJxF PID will indicate YES. |

The alternative fuel control module (AFCM) monitors the gasoline injector driver outputs. A fault is set when the AFCM detects an electrical load failure on the output circuit. |
|
The gasoline fuel injector resistance is 11.0 to 18.0 ohms. |
| P0605 - Alternative Fuel Control Module Read Only Memory (ROM) Error | This fault is set when the alternative fuel control module (AFCM) ROM has been corrupted. |
|
Retrieve and record the DTCs. Clear the DTCs. Repeat the self-test. If DTC P0605 is retrieved again, install a new AFCM. |
| P0606 - Alternative Fuel Control Module Internal Communication Error | This fault indicates an alternative fuel control module (AFCM) internal communications error. |
|
Retrieve and record the DTCs. Clear the DTCs. Repeat the self-test. If DTC P0606 is retrieved again, install a new AFCM. |
| P1261 - Cylinder 1 Alternative Fuel Injector Circuit Low P1262 - Cylinder 2 Alternative Fuel Injector Circuit Low P1263 - Cylinder 3 Alternative Fuel Injector Circuit Low P1264 - Cylinder 4 Alternative Fuel Injector Circuit Low P1265 - Cylinder 5 Alternative Fuel Injector Circuit Low P1266 - Cylinder 6 Alternative Fuel Injector Circuit Low P1267 - Cylinder 7 Alternative Fuel Injector Circuit Low P1268 - Cylinder 8 Alternative Fuel Injector Circuit Low P1271 - Cylinder 1 Alternative Fuel Injector Circuit High P1272 - Cylinder 2 Alternative Fuel Injector Circuit High P1273 - Cylinder 3 Alternative Fuel Injector Circuit High P1274 - Cylinder 4 Alternative Fuel Injector Circuit High P1275 - Cylinder 5 Alternative Fuel Injector Circuit High P1276 - Cylinder 6 Alternative Fuel Injector Circuit High P1277 - Cylinder 7 Alternative Fuel Injector Circuit High P1278 - Cylinder 8 Alternative Fuel Injector Circuit High |
The alternative fuel control module (AFCM) monitors the alternative fuel injector driver outputs. A fault is set when the AFCM detects an electrical load failure on the output circuit. |
|
The alternative fuel injector resistance is 2.0 to 15.0 ohms. |
| U1011 - SCP Invalid Or Missing Data | The powertrain control module (PCM) and alternative fuel control module (AFCM) transfer data through the SCP network. A fault is set when the AFCM does not receive or receives incorrect data from the PCM. |
|
Carry out the PCM self-test to verify communication. Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE for PCM diagnostic trouble codes. |
| U1260 - SCP Single Ended (+) Circuit Failure U1261 - SCP Single Ended (-) Circuit Failure |
The powertrain control module (PCM) and alternative fuel control module (AFCM) transfer data via the SCP network. A fault indicates a communication error on one circuit of the SCP communication. |
|
Carry out the PCM self-test to verify communication. Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE for PCM diagnostic trouble codes. |
| U1262 - SCP Communication Bus Fault | DTC U1262 indicates that the alternative fuel control module (AFCM) has not received messages from the powertrain control module (PCM) for longer than 5 seconds. |
|
Carry out the PCM self-test to verify communication. Refer to INTRODUCTION - CNG, FLEX-FUEL & GASOLINE for PCM diagnostic trouble codes. |
| U0309 - Software Incompatibility with Alternative Fuel Control Module | DTC U0309 indicates that an incorrect alternative fuel control module (AFCM) has been installed. |
|
Verify the AFCM part number corresponds to the current vehicle application. |
