Component Description
FUEL CUT SOLENOID VALVE
When the ignition switch is off, the ECM turns the fuel cut solenoid
valve OFF (under this condition, no current flows through the fuel
cut solenoid valve), shutting off fuel supply.
When the engine is not operating due to trouble, the fuel cut sole-
noid valve may or may not be OFF even when the ignition switch
is ON.

Component Description
CRANKSHAFT POSITION SENSOR (TDC)
The crankshaft position sensor (TDC) monitors engine speed by
means of signals from the sensing plate (with four protrusions)
installed to the clutch housing. The datum signal output is detected
at ATDC 30É and sent to the ECM. The sensor signal is used for
fuel injection control and fuel injection timing control.

IPre-glow
When the ignition switch is turned on the ON position, the glow
indicator lamp will turn ON and pre-glow starts.
The glow relay is turned ON continuously. The ON time of both
the glow indicator lamp and the glow relay is determined by the
engine coolant temperature. Pre-glow ends when the pre-glow
time elapses or when the engine is started.
IIntermediate glow
Intermediate glow starts when the pre-glow time has elapsed
and the engine has not been started. The glow relay is turned
ON intermittently. Intermediate glow ends when the intermedi-
ate glow time has elapsed, or when the engine is started.
IAfter-glow
After-glow starts as soon as the engine is running and the
engine coolant temperature is below 50ÉC (122ÉF). The glow
relay is turned on continuously. After-glow ends when the after-
glow time elapses, or when the engine coolant temperature
exceeds 50ÉC (122ÉF).

* Engine coolant temperature is higher than 20ÉC
(68ÉF).
* Repeatedly turning the ignition switch to ªONº posi-
tion and then back to ªLOCKº position may change
the glow time.

Overall Function Check
Use this procedure to check the overall function of the vehicle
speed sensor circuit. During this check, a DTC might not be con-
firmed.
WITH CONSULT-II
1) Jack up drive wheels.
2) Start engine.
3) Read vehicle speed sensor signal in ªDATA MONITORº mode
with CONSULT-II.
The vehicle speed on CONSULT-II should be able to exceed 10
km/h (6 mph) when rotating wheels with suitable gear position.
WITHOUT CONSULT-II
1) Jack up drive wheels.
2) Rotate drive wheel by hand.
3) Check voltage between ECM connector terminal
417and body
ground with tester.
Voltage should vary between approx. 0 - Battery voltage.
