DTC DESCRIPTION P016D - EXCESSIVE TIME TO ENTER CLOSED LOOP FUEL PRESSURE CONTROL
| Description: | On every engine start with fuel temperature less than 40°C (104°F), the PCM checks the accuracy of the fuel rail pressure sensor by estimating the amount of effort required by the fuel pressure control valve to maintain pressure for a given fuel rail pressure reading. This DTC sets when the system is unable to successfully learn the effort required over a substantial period of time. This DTC indicates that some element of the fuel system is operating within plausible tolerances, but with too much variation to get a stable reading. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | When in fuel pressure control valve operating mode, the system evaluates the control signal required for the fuel pressure control valve and adjusts to the expected value. This DTC sets if the new adjustment value is not learned in a given time. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| All | GO to PINPOINT TEST M . | ||
