Daewoo Musso. Manual - part 156

M162 ENGINE CONTROLS  1F1-63

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.

 Specified Value

 > 50mbar

  (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.
