2–742

DTC: P119F

P119F: Fuel rail pressure sensor - rationality

INFORMATION
1. Technical description
• The common rail pressure sensor consistently measures common rail pressure.
<Description of malfunction>
• Common rail pressure cannot be correctly sensed.
• Malfunction is likely to have occurred in the common rail pressure sensor.
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 stopped, or the engine speed remains at 500 r/min or more for 5 seconds or more.
• Common rail pressure is 220 MPa or less.
(2) Judgement criteria
P119F is detected under the conditions described below. 1 and 2 represent the order of priority.
• The difference obtained by subtracting the common rail pressure sensor power (main) from the common rail
pressure sensor power (sub) continues to be more than 1.06 V for 3 seconds or more, or the difference
obtained by subtracting the common rail pressure sensor power (main) from the common rail pressure sensor
power (sub) continues to be less than 0.04 V for 3 seconds or more.
3. Reset condition
• After normal operation is restored.
4. Indication, warning or system control regulation when the DTC is set.
• MIL: ON
• SVS light: OFF
• Cruise control is not available.
• Idling stop system is not available.
5. Symptoms on the vehicle when the DTC is set
<Symptoms on the vehicle due to backup control (fail safe function)>
• Cruise control does not work.
• Idling stop system does not work.
<Symptoms on the vehicle due to malfunction>
