DTC P0454-00: Fuel Tank Pressure Sensor Intermittent Malfunction: Notes
DTC P0454:00 PCM (SKYACTIV-G 2.5 - WITH CYLINDER DEACTIVATION) DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0454:00 |
FUEL TANK PRESSURE SENSOR INTERMITTENT MALFUNCTION |
| DETECTION CONDITION |
- Any one of the following conditions is met:
- The difference between the currently detected fuel tank pressure sensor input voltage and the previously detected input voltage is large.
- The input voltage of the fuel tank pressure sensor remains low or high.
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
- FREEZE FRAME DATA/Snapshot data is available.
- DTC is stored in the PCM memory.
