| DTC P0193:00 |
Fuel pressure sensor circuit high input |
| DETECTION CONDITION |
- If the input voltage at the PCM terminal 1CA is more than 4.86 V
for 5 s
, the PCM determines that the fuel pressure sensor circuit is high.
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Stops high pressure fuel pump control
- Limits intake air amount
|
| POSSIBLE CAUSE |
- Fuel pressure sensor connector or terminals malfunction
- PCM connector or terminals malfunction
- Fuel pressure sensor malfunction
- Short to power supply in wiring harness between fuel pressure sensor terminal B and PCM terminal 1CA
- Open circuit in wiring harness between the following terminals:
- Fuel pressure sensor terminal C-PCM terminal 1BJ
- Fuel pressure sensor terminal B-PCM terminal 1CA
- Fuel pressure sensor terminal A-PCM terminal 1CB
- PCM malfunction
