DTC P0192-00; High Fuel Pressure Sensor Circuit Low Input: Notes
DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0192:00 |
High fuel pressure sensor circuit low input |
| DETECTION CONDITION |
- If the input voltage at the PCM terminal 1CA is less than 0.74 V for 5 s, the PCM determines that the fuel pressure sensor circuit is low (U.S.A.).
- If the input voltage at the PCM terminal 1CA is less than 0.16 V for 5 s, the PCM determines that the fuel pressure sensor circuit is low (Except U.S.A.).
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/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 |
- High fuel pressure sensor connector or terminals malfunction
- PCM connector or terminals malfunction
- Short to ground in wiring harness between the following terminals:
- High fuel pressure sensor terminal E-PCM terminal 1CI
- High fuel pressure sensor terminal C-PCM terminal 1BO
- High fuel pressure sensor signal circuit and ground circuit are shorted to each other
- High fuel pressure sensor malfunction
- High pressure fuel pump malfunction
- PCM malfunction
