DTC P0192-00: Fuel Pressure Sensor Circuit Low Input: Outline
DTC P0192:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE
| System malfunction location |
Fuel pressure sensor circuit low input |
| Detection condition |
- If the input voltage at the PCM terminal 1W is less than 0.51 V for 5 s, the PCM determines that the fuel pressure sensor circuit is low.
|
| Fail-safe |
- Stops high pressure fuel pump control
- Limits intake air amount
|
| Possible cause |
- Fuel pressure sensor connector or terminals malfunction
- PCM connector or terminals malfunction
- Short to ground in any of the following fuel pressure sensor circuits.
- Power supply circuit
- Signal circuit
- Short circuit in fuel pressure sensor signal circuit and ground circuit
- Fuel pressure sensor malfunction
- High pressure fuel pump malfunction
- PCM malfunction
