DTC: P0192 and P0193

P0192: Fuel rail pressure sensor (main) - out of range (Out of range low)
INFORMATION
1. Technical description
• The common rail pressure sensor consistently measures common rail pressure.
<Description of malfunction>
• Common rail pressure cannot be correctly sensed.
2. DTC set condition
(1) DTC detection condition
• Starter key "ON".
• Battery voltage is in the range of 10 V to 16 V.
• The engine is stopped, or the engine speed remains at 500 r/min or more for 5 seconds or more.
(2) Judgement criteria
• Output of the common rail pressure sensor (main) remains at 0.7 V (-10.7 MPa) or lower for 0.2 seconds or
longer.
3. Reset condition
• After restoration to normal condition and starter key "LOCK"
4. Indication, warning or system control regulation when the DTC is set.
• MIL: ON
• SVS light: OFF
5. Symptoms on the vehicle when the DTC is set
<Symptoms on the vehicle due to backup control (fail safe function)>
• –
<Symptoms on the vehicle due to malfunction>
• –
6. Pre-inspection work
• Check that the battery voltage is in the normal range.
7. After-inspection work
• Clear all past DTCs.
• Check that no DTC is stored after test drive.
