Injector Spray Pattern Check

1. Turn the ignition switch OFF.

2. Remove the fuel injector connectors.

3. Remove the fuel distributor and injector with a unit. At

this time, do not remove the supply and return line.

Notice

Prepare the beaker for taking the fuel.

4. Connect the shop made cable to the injector with a firing

order.

5. Connect the other end of shop made cable to the positive

battery cable and negative battery cable.

6. Turn the ignition switch ON.

7. Check the injector for normal spray pattern as shown in

the figure. Check injector for leaks or later drop

Injector Resistance Inspection

1. Turn the ignition switch OFF.

2. Remove the fuel injector connectors.

3. Measure the fuel injector coil resistance using a

multimeter.

Notice

Replace the fuel injector if the measured value is out
of the specified values. Check the connector and wire
connection between the ECM and the injector if the
measured values are normal.

Injector Pulse Width Inspection

1. Turn the ignition switch OFF.

2. Install the scan tool.

3. Turn the ignition switch ON.

4. Monitor the “INJECTION TIME” with a scan tool.

PURGE CONTROL VALVE

The fuel vaporization control system is in stalled to inhibit the fuel vaporized gas from discharging into the atmosphere.

The fuel vaporized gas that is accumulated in the canister abstracts through the purge control valve purification during
the engine combustion (except the decreasing mode) and coolant temperature of over 80°C. For this reason, the Engine
Control Module (ECM) transacts the engine speed, air inflow quantity, coolant temperature, and intake temperature.

The purge control valve is activated by the ECM frequency according with the engine rotating speed to adjust the
purification rate. The purification rate is determined by the continuous valve opening interval.

The purge control valve is activated by the ECM for the following conditions:

• Coolant temperature of over 80°C

• Engine speed of over 1,000 rpm

• 2 minutes after starting

• When the fuel cut-off mode is not activated

4. Remove the line to canister and measure the pressure

with the vacuum pressure gauge.

Test

1. Maintain the normal temperature and idling state by

operating the engine.

2. Connect the ECM terminal No. 11 and No. 34 and check

for normal operation through the output waves using
oscilloscope.

Notice
Test during purge control valve operation after the
minimum of 1 minute after the engine turned on.

3. Connect the ECM terminal No. 34 and No.10 and check

for current consumption during the ignition switch ON.

Notice
Test while at normal temperature and at idling state
by operating the engine.
