WARNING: This page is about a different variant/trim than selected.
P2541:00 (PCM - VIN Y) DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
Low fuel pressure sensor circuit low input |
| Detection condition |
- If the input voltage at the PCM terminal 1BL is standard or less, the PCM determines that the low fuel pressure sensor circuit is low.
Precondition
- Battery voltage: 8 V or more
|
| Fail-safe |
- Limits the engine torque or the upper limit of the engine speed.
|
| Possible cause |
- Malfunction in wiring harness (including connector/terminal) between PCM and low fuel pressure sensor/fuel temperature sensor (see CIRCUIT INSPECTION
.) (see CONNECTOR INSPECTION
.)
- Low fuel pressure sensor malfunction (Refer to LOW FUEL PRESSURE SENSOR INSPECTION (VIN Y)
in the service information.)
- PCM malfunction (Refer to applicable PCM REMOVAL/INSTALLATION (VIN Y)
in the service information.)
|
| Repeatability verification procedure |
- Clear the DTC recorded in the memory. (see CLEARING DTC
.)
- Perform the KOEO or KOER self test. (See DTC INSPECTION
