DTC P0192-00: Fuel Pressure Sensor Circuit Low Input: Notes
DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0192:00 |
Fuel pressure sensor circuit low input |
| DETECTION CONDITION |
- If the input voltage at the PCM terminal 1 CA is less than 0.156 V
for 5 s
, the PCM determines that the fuel pressure sensor circuit is low.
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.
- The DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Stops the high pressure fuel pump control.
- Limits the intake air amount.
|
| POSSIBLE CAUSE |
- Fuel pressure sensor connector or terminals malfunction
- Short to ground in wiring harness between the following terminals:
- Fuel pressure sensor terminal C-PCM terminal 1BJ
- Fuel pressure sensor terminal B-PCM terminal 1CA
- PCM connector or terminals malfunction
- Fuel pressure sensor signal circuit and ground circuit are shorted to each other
- Open circuit in wiring harness between fuel pressure sensor terminal C and PCM terminal 1BJ
- Fuel pressure sensor malfunction
- PCM malfunction
