ft&;K ENGINE/MALFUNCTION INDICATO
R
Among the on-board diagnostic items, a check engine/mal-
function indicator lamp comes on to notify the driver of the
emission control items when an irregurality is detected. However, when an irregular signal returns to normal and the
engine control module judges that it has returned to normal,
the check engine/malfunction indicator lamp 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 does
not come on until the irregularity is detected. Here, immediately after the ignition switch is turned on, the
check engine/malfunction indicator lamp is lit for 5 seconds to
indicate that the check engine/malfunction indicator lamp op-
erates normally.

MALFUNCTION INDICATOR LAMP

Heated oxygen sensor
Volume air flow sensor
Intake air temperature sensor
Throttle position sensor
Engine coolant temperature sensor
Crankshaft position sensor
Camshaft position sensor
Barometric pressure sensor

Ignition coil, Ignition power transistor unit
CHECK ENGINE/MALFUNCTION INDICATOR LAMP INSPECTION
(1) Check to be sure, when the ignition switch is set to the “ON” position, that the lamp illuminates for about five sec-
onds and then switches OFF.
(2) If the lamp does not illuminate, check for damage or dis-
connection of the harness, or for a blown fuse or a failed
light bulb.
