14-58FUEL SYSTEM -MPI System Inspection <1.8L Engine>
MALFUNCTION INDICATOR LIGHTNWQAB
Among the self-diagnosis items, a malfunction indicator light
comes on to notify the driver of the emission control items
when an irregularity is detected.
However, when an irregular signal returns to
notmal ‘and the
engine control unit judges that it has returned to normal, the
malfunction indicator light goes out.
Moreover, when the ignition switch is turned off, the light goes
out. Even if the ignition switch is turned on again, the light doesnot come on until the irregularity is detected.
Here, immediately after the ignition switch is turn on, the
malfunction indicator light is lit for 5 seconds to indicate that
the malfunction indicator light operates normally.
Items indicated by the lightening malfunction light
Engine control unit
Oxygen sensor
Air-flow sensor
Intake air temperature sensor
Throttle position sensor
Motor position sensor
Engine coolant temperature sensor
Crank angle sensor
No. 1 cylinder TDC sensor
Barometric pressure sensor
Ignition timing adjustment signal
Injector
Fuel pump
EGR system
The malfunction indicator light lights up when the ignition
timing adjustment terminal is short-circuited
,‘t’o ground.
Consequently, it lights up ,when the ignition timing
adjustment is grounded when adjusting ignition timing,
but in this case there is no abnormality.
MALFUNCTION INDICATOR LIGHT INSPECTlON
When turning on the ignition switch, check that the light comes
on.
NOTElf the light does not come on, check the harness and light for
breakage.SELF-DIAGNOSIS
Nl4PMFaThe engine control unit monitors the input/output signals
(some signals at all times and the others under specified
conditions) of the engine control unit.
Page 513 of 1216
FUEL SYSTEM - MPI System inspection <1.8L Engine>14-59
--..When it is noticed that an irregularity has continued for a
specified time or longer from when the irregular signal is
initially monitored. Passing a certain number, the engine
control unit judges that an irregularity has occurred, memorizesthe malfunction code, and outputs the signal to the
self-diagnosis output terminal.
There are 14 diagnosis items, and the diagnosis results can beread out with a voltmeter.
Moreover, since memorization of the malfunction codes is
backed up directly by the battery, the diagnosis results are
memorized even if the ignition key is turned off. The malfunc-
tion codes will, however, be erased when the battery terminal
or the engine control unit connector is disconnected.
Caution
If the sensor connector is disconnected with the ignition
switch turned on, the malfunction code is memorized. In
this case, disconnect the battery terminal’
(-) for 10seconds or more, and the diagnosis memory will be
erased.The 14 diagnosis items are provided as follows, and if plural
items are activated, they are all indicated sequentially from thesmallest code number.
perature sensor
CautionFor the malfunction code of the ignition timing adjustment
signal, the light for the ignition timing adjustment terminal
lights up when short-circuited to ground.
Consequently, it is output when the ignition timing
adjustment is grounded when adjusting ignition timing,
but in this case there is not abnormality.
CHECK PROCEDURE (SELF-DIAGNOSIS)N14PCAElPrecautions for Operation
(1) When battery voltage is low, no detection of failure is
possible. Be sure to check the battery for voltage and otherconditions before starting the test.
(2) Diagnosis item is erased if the battery or the engine controlunit connector is disconnected. Do not disconnect the
battery before the diagnosis result is completely read.
(3) After check and correction are over, disconnect ground
cable for
10 seconds or more from negative terminal of
battery and connect it again to make sure that failure code
is erased.

SERVICE ADJUSTMENT PROCEDM%,&ACCELERATOR CABLE
CNSPECTION AN&I ”ADJUSTMENT
For models equipped with the auto-cruise control systemreferto
P.14-136.(1) Turn air conditioner and lights OFF.
Inspect and adjust at no load.
2) Warm engine until stabilized at idle.
3) Confirm idle speed is at prescribed rpm.
4) Stop engine (ignition switch OFF).
5) Confirm there are no sharp bends in accelerator cable.
6) Check inner cable for correct slack.
7) If there is too much slack or no slack, adjust play by the
following procedures.
@ On models with an SOHC engine, turn the ignition
switch to the ON position (without starting the engine)
and leave in that condition for approximately 15
seconds.@
Loosen the adjusting bolts on the air intake plenum, andthen secure the outer cable so that the free play of the
inner cable will be the standard value.
Standard value:
jlr
3-5 mm (.12-.20 in.)
NOTEIf there is excessive play of the accelerator cable, the
vehicle speed drop (“undershoot”) when climbing a slope
will be large.
If there is no play (excessive tension) of the accelerator
cable, the idling speed will increase.
(8) After adjusting, confirm that throttle valve fully opens and
closes by operating pedal.
(9) Adjust accelerator cable play and confirm throttle lever
stopper touches the idle switch.
ACCELERATOR SWITCH INSPECTION AND
ADJUSTMENT
NlWlEB(1) After warming up the engine, check to be sure that the
accelerator switch is ON when the accelerator pedal’ is in
the free condition. If there is a malfunction, adjust by using
the adjusting bolt.
(2) Press the accelerator pedal by hand until the accelerator
switch switches from ON to OFF and confirm that the
amount of pedal movement (A in the figure) is within the
standard value range.
Standard value:
Accelerator switch switching point
2-6 mm
(.08-.24 ‘in.)
(3) If the distance (A in the figure) is not within the standard
value, adjust it by using the adjusting bolt.
