TROUBLESHOOTING
2. Access following PIDs:
• ECTPID
• IATPID
• TPVPI D
3. Check the PID values.
• If all checks okay, test:
— Pressure regulator
— PRC solenoid valve
— Wiring between PRC solenoid valve and
PCM terminal 95 (Open circuit)
— Wiring between main relay and PRC
solenoid valve (Open circuit)
Inspection 2
1. Connect the SSTs (NGS) to DLC.

2. Access following PIDs:
• ECTPID
• IATPID
• If all checks okay, test:
— Loose or damaged vacuum hose between
the pressure regulator, PRC solenoid
valve, and intake manifold.
— PRC solenoid valve.
— Wiring between PRC solenoid valve and
PCM terminal 95 (Short circuit).
Fuel Cut Control Inspection
1. Warm up engine and let it idle.
2. Turn off the electrical loads and A/C switch.
3. Connect the
SSTs
(NGS tester) to the DLC.
PROGRAM CARD
4. Select the PID/DATA MONITOR AND RECORD
function on the NGS display.
5. Select RPM and INJ or FUEL PW1 PIDs.
6. Press START.
7. Monitor both PIDs while performing the following
steps.
(1) Depress the accelerator pedal and increase
the engine speed to 4000 rpm.
(2) Release the accelerator pedal (brake pedal is
not depressed) and verify that the fuel injector
duration time is 0 msec., and 2—5 msec,
when the engine speed drops below 2500
rpm.
• If not as specified, carry out the following:
— ECT sensor inspection
— Neutral/clutch switch inspection (MTX)
— TR switch inspection (ATX)
Fuel Pump Operation Inspection
Except for GF4A-EL models
1. Connect the
SSTs
(NGS tester) to the DLC.
PROGRAM CARD
NGS SET
2. Remove the fuel-filler cap.
3. Turn the ignition switch on.
4. Select the SIMULATION TEST function on the
NGS display.
5. Turn the fuel pump relay from off to on using the
FP RLY PID and inspect if the operation sound is
heard.
• If no operation sound is heard, measure the
voltage at harness side fuel pump unit
connector terminal B.
• If the voltage is as specified, inspect the
following.
— Fuel pump continuity
— Fuel pump GND
— Wiring harness between fuel pump relay
and PCM terminal 4P.
• If not as specified, inspect the following.
— Fuel pump relay
— Wiring harness and connector
(Main relay - fuel pump relay - fuel pump
unit)
