DTC P0193:00: Notes
DTC P0193:00 (L3 WITH TC) DETECTION CONDITION & POSSIBLE CAUSES
| DTC P0193:00 |
Fuel pressure sensor circuit high input |
| DETECTION CONDITION |
- If the input voltage from the fuel pressure sensor is more than 4.8 V
for 5.3 s
, the PCM determines that the fuel pressure sensor circuit is high.
Diagnostic support note
- This is a continuous monitor (CCM).
- The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- Fuel pressure sensor connector or terminals malfunction
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between fuel pressure sensor terminal B and PCM terminal 2R
- Fuel pressure sensor power supply circuit and signal circuit are shorted to each other.
- Open circuit in wiring harness between the following terminals:
- Fuel pressure sensor terminal B-PCM terminal 2R
- Fuel pressure sensor terminal A-PCM terminal 2P
- Fuel pressure sensor malfunction
- PCM malfunction
