DTC P0089 Pressure Control Valve Plausibility to Consume Current High Intensity

DTC P1271 Fuel Regulator Circuit Malfunction (EDU Drive)


DESCRIPTION

Based on signals from the ECM, the pressure control valve opens when sudden deceleration occurs, or when the ignition switch is turned off, to prevent the fuel pressure from becoming too high.

DTC No.
DTC Detection Condition
Trouble Area
P0089
  1. Open or short in pressure control valve circuit (DTC P1271 set simultaneously)
    (The MIL is illuminated and a DTC is immediately set when a malfunction is detected)
  2. ECM internal error (DTC P1271 not set)
    (The MIL is illuminated and a DTC is immediately set when a malfunction is detected)
  1. Open or short in pressure control valve circuit
  2. Common rail assembly (pressure control valve)
  3. ECM
P1271
  1. Open or short in pressure control valve circuit
    (The MIL is illuminated and a DTC is immediately set when a malfunction is detected)
УКАЗАНИЕ:
These DTCs are set when the ignition switch is in the ON position.

INSPECTION PROCEDURE

УКАЗАНИЕ:
Read freeze frame data using an intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
1.READ OUTPUT DTCS (DTC P0089 AND/OR P1271)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to the ON position.

  1. Turn the tester on.

  1. Enter the following menu items: Powertrain / Engine and ECT / DTC.

  1. Read the DTCs.
