Notice Replace the fuel pump relay if the measured value is over 9A.
Notice Check the fuel filter and fuel line when the fuel delivery is not within specified value.
Measure the Current Consumption of Fuel Pump
1. Remove the fuel pump relay from fuse and relay box in trunk, and turn the ignition switch to "ON" position.
2. Using a multi-tester, measure the current consumption by connecting the terminal No.1 and No.3 of pump.
Measure the Fuel Delivery From the Fuel Pump
1. Disconnect the return pipe from fuel distributor and insert
the appropriate hose into it.
2 . Place the hose end into the beaker with the minimum capacity of 1Liter.
3. Turn the ignition switch to "ON" position.
4. Connect the terminal No.33 and No.5 of ECU with a service wire.
5. Measure the fuel delivery from the fuel pump.

PURGE SWITCHOVER VALVE
1 Purge Switchover Valve
2 Line to Engine
3 Line to Canister
4 Canister
Functions The fuel vaporization control system is installed to inhibit the fuel vaporized gas from discharging into the atmosphere. Thefuel vaporized gas that is accumulated in the canister abstractsthrough the purge switchover valve purification during the engine combustion (except the decreasing mode) and coolant temperature of over 80 °C. For this reason, the ECU transacts
the engine speed, air inflow quantity, coolant temperature, andintake temperature. The purge switchover valve is activated by the ECU 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 switchover valve is activated by the ECU for the following conditions :
Coolant temperature of over 80 °C
Engine speed of over 1000rpm
2 Minutes after starting
When the fuel cut-off mode is not activated

M162 ENGINE CONTROLS 1F1-63
4. Remove the line to canister and measure the pressure withthe 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.

1F1-66 M162 ENGINE CONTROLS Crankshaft Position Sensor Resistance Inspection
1. Disconnect the coupling "E" of ECU while the ignition switchis 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
Specified Value > 20k
Crankshaft Position Sensor Insulator Resistance Inspection
1. Disconnect the engine coupling from ECU while the ignition
switch is in "OFF" position.
