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 ECU terminal No.11 and No.34 and check for
normal operation through the output waves using the
scanner.
Notice
Test during purge control switchover valve operation after
the minimum of 1 minute after the engine turned on.
3. Connect the ECU terminal No.34 and No.10 and check for
current consumption during the ignition switch ON.

(after approx. 1min.)
purge switchover valve
operates at this time
Notice
Test while at normal temperature and at idling state by
operating the engine.

Crankshaft Position Sensor Resistance
Inspection
1. Disconnect the coupling "E" of ECU while the ignition switch
is in "OFF" position.
2. Measure the resistance between the coupling terminal pin
No.99 and No.100 using a multimeter.
Notice
Measure the insulator resistance of the crankshaft position
sensor if out of the specified value.
Crankshaft Position Sensor Output Wave
Inspection
1. Connect the test box to the ECU.
2. Measure the output wave between the ECU terminals No.99
and No.100 using the scanner or the oscilloscope while
engine cranking (starter motor activated).
Notice
Check the segment or crankshaft position sensor and air
gap if cannot get the output wave as shown in the figure.
Specified Value
1050 - 1400
W
Specified Value
> 20k
W
Crankshaft Position Sensor Insulator Resistance
Inspection
1. Disconnect the engine coupling from ECU while the ignition
switch is in "OFF" position.
2. Measure the resistance between the coupling terminal pin
No.100 and No.69.
Notice
Measure the check and ground terminal of the crankshaft
position sensor if out of the specified value.
