DTC Description
 
 
DTC DETECTION LOGIC
noteDTC P0087 may be displayed when running out of gas.
DTCM.U.T.-III SE screen terms
(Trouble diagnosis content)
DTC detection condition
P008700LOW FUEL PRES
(Fuel rail/system pressure - too low)
Diagnosis conditionEngine running at idle
Signal (terminal)Fuel rail pressure signal
ThresholdECM detects that the difference between target fuel pressure and fuel rail pressure sensor signal is 2,700 kPa (27 bar, 27.54 kg/cm2, 319.5 psi)
Diagnosis delay time5 seconds or more
 
 
POSSIBLE CAUSE
  • Fuel system
  • Leakage in fuel line
  • High pressure fuel pump
  • Low pressure fuel pump
  • Damage in lifter
  • Out of gas
  • Harness or connector
  • Fuel Pressure sensor
  • Fuel Injector stuck open
  • Crogged in fuel line
  • High Pressure fuel pump cam and lifter
 
 
FAIL-SAFE
Engine operating condition in fail-safe mode
Fail safe modeVehicle behavior
Traveling control modeAccelerator angle variation controlECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.
noteECM does not control the accelerator pedal releasing speed.
Device fix mode
  • This mode fixes the electric IVT motor and the EVT control solenoid valve in the reference position.
  • The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).
  • A control signals is not transmitted to EGR volume control valve and the EGR volume control is deactivated.
Combustion control modeStratified charge combustion control at startingNo stratified charge combustion at starting (cold start).
 
 
DTC Confirmation Procedure
1.CHECK DTC PRIORITY
If DTC P0087 is displayed with other DTC, first perform the trouble diagnosis for other DTC.
Is applicable DTC detected?
Perform diagnosis of applicable. DTC Index.
.
 
2.CHECK FUEL LEAKAGE
  1. Turn ignition switch ON.
  2. Visually check the piping between low pressure fuel pump and fuel injectors for fuel leakage.
  3. Start the engine.
  4. Visually check the piping between low pressure fuel pump and fuel injectors for fuel leakage.
Is inspection result normal?
.
Repair or replace error-detected parts.
 
3.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
TESTING CONDITION:
  • Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.
  • Before performing the following procedure, check that the fuel tank is 1/8 full of fuel.

4.PERFORM DTC CONFIRMATION PROCEDURE-1
With M.U.T.-III SE
  1. Turn ignition switch ON.
  2. Select “COOLANT TEMP/S” in “DATA MONITOR” mode of “ENGNE” using M.U.T.-III SE.
  3. Check the following condition;
    COOLANT TEMP/S: 5 – 40°C (41 – 104°F)
With GST
Follow the above steps for “With M.U.T.-III SE”.
Is the condition satisfied?
.
  1. Satisfy the condition.
  2. Retry from step 2.
 
5.PERFORM DTC CONFIRMATION PROCEDURE-2
With M.U.T.-III SE
  1. Start the engine and let it idle for 10 seconds.
  2. Check 1st trip DTC.
With GST
Follow the above steps for “With M.U.T.-III SE”.
Is 1st trip DTC detected?
Proceed to DTC Diagnosis Procedure.
.
 
6.PERFORM DTC CONFIRMATION PROCEDURE-3
With M.U.T.-III SE
  1. Select “COOLANT TEMP/S” in “DATA MONITOR” mode of “ENGINE” using M.U.T.-III SE.
  2. Maintain the following condition for 10 seconds or more at idle.
    COOLANT TEMP/S: 70°C (104°F) or more
  3. Check 1st trip DTC.
With GST
Follow the above steps for “With M.U.T.-III SE”.
Is 1st trip DTC detected?
Proceed to DTC Diagnosis Procedure.
