P0149 - FUEL TIMING ERROR
| Description: | The powertrain control module (PCM) monitors the injection timing from the injector driver feedback circuit during the vehicle deceleration. The PCM also compares the difference between actual fuel pressure and desired fuel pressure, to the calibrated value. The DTC is set when the injection timing or the difference between the actual and desired fuel pressure are out of the calibrated range. | |||
| Possible Causes: |

|||
| Diagnostic Aids: | After reprogramming the PCM verify that the DTC is repaired. The vehicle may require driving to verify the repair. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory | |
| All | Check for other DTCs or drive symptoms for further action. If other DTCs are not present reprogram the PCM and repeat the self-test. If the DTC is present after programming, install a new PCM. Make sure to check for aftermarket performance products before installing a new PCM.
