WIRING DIAGRAM
INSPECTION PROCEDURE
HINT:
SAfter completing repairs, check that P0087 is not present again.
SIf different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may have an open circuit.
SRead freeze frame data using the hand−held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
1READ VALUE OF HAND−HELD TESTER(FUEL PRESSURE)
(a) Connect the hand−held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand−held tester ON.
(c) Start the engine.
(d) Select the item ”DIAGNOSIS / OBD/MOBD / DATA LIST / ALL / COMN RAIL”.
(e) Check that internal fuel pressure of the common rail is within the specification below.
Reference:
Engine SpeedFuel Pressure (MPa)
IdlingApproximately 30 to 40
2,500 rpm (No engine load)Approximately 50 to100

2 CHECK IF DTCS OUTPUT RECUR(FUEL PRESSURE SENSOR DTCS)
(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand −held tester ON.
(c) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CLEAR CODES”.
(d) Clear the DTCs.
(e) Let the engine idle for 60 seconds, and repeat quick engine RPM acceleration (to 2,500 rpm) for 30 seconds.
(f) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODES”.
(g) Read DTCs.

REPLACE ECM (See page 10− 29)
3 CHECK HARNESS AND CONNECTOR(FUEL PRESSURE SENSOR − ECM)
(a) Disconnect the E 12 and E 13 ECM connectors.
(b) Disconnect the F 16 fuel pressure sensor connector.
(c) Check the resistance between the wire harness side con-
nectors.
