FUEL RAIL PRESSURE RELIEF VALVE
With CONSULT-II
WARNING:

Confirm that the engine is cooled down and there are no fire hazards near the vehicle.

Prepare pans or saucers under the disconnected fuel line because the fuel may spill out.
1. Turn ignition switch OFF.
2. Remove fuel hose from fuel rail pressure relief valve.
3. Attach a blind cap or plug to removed hose.
4. Turn ignition switch ON.
5. Select “PRES REGULATOR” in “ACTIVE TEST MODE” with
CONSULT-II.
6. Start engine and keep engine speed 2,000 rpm.
7. Raise fuel pressure to 160 MPa with touching “UP” or “Qu” on
the CONSULT-II screen.
8. Confirm that the fuel does not come out from the fuel rail pres-
sure relief valve.
WARNING:

Be careful not to allow leaked fuel to contaminate engine
compartment. Especially, ensure to keep engine mount
insulator clear of fuel.

If the fuel comes out, stop the engine immediately.

DTC P0102, P0103 MAF SENSOR

DTC P0102, P0103 MAF SENSORPFP:22680
Component DescriptionEBS011YG
The mass air flow sensor is placed in the stream of intake air. It mea-
sures the intake flow rate by measuring a part of the entire intake
flow. The mass air flow sensor controls the temperature of the hot
wire to a certain amount. The heat generated by the hot wire is
reduced as the intake air flows around it. The more air, the greater
the heat loss.
Therefore, the electric current supplied to hot wire is changed to
maintain the temperature of the hot wire as air flow increases. The
ECM detects the air flow by means of this current change.
CONSULT-II Reference Value in Data Monitor ModeEBS011YH
Specification data are reference values.
This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.
On Board Diagnosis LogicEBS011YJ
The MI will not light up for these self-diagnoses.

NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Wait at least 5 seconds.

Specification data are reference values, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic ProcedureEBS011YM
1. CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Loosen and retighten ground screws on the body. Refer to EC-1424, "
