PREPARATION:
Remove the air filter.
CHECK:
Visual check that the air filter is not excessively dirty or oily.
NG Repair or replace
air filter.
OK
5 Check idle speed.
PREPARATION:
(a) Warm up the engine to the normal operating temperature.
(b) Switch off all the accessories.
(c) Switch off the A/C.
(d) Shift the transmission into the N position.
(e) Connect the OBD II scan tool or hand-held tester to the DLC3 of the vehicle.
CHECK:
Use CURRENT DATA to check the idle speed.
OK:
Idle speed:
650 to 750 rpm

PREPARATION:
(a) Disconnect the ignition coil.
(b) Remove the spark plug.
(c) Install the spark plug to the ignition coil.
(d) Disconnect the injector connector.
(e) Ground the spark plug.
CHECK:
Check if spark occurs while the engine is being cranked.
NOTICE:
To prevent excess fuel from being injected from the injec-
tors during this test, don't crank the engine for more than
5 to 10 seconds at a time.
NG Proceed to page IG-1 and continue to trouble-
shoot.

9. DEFINITION OF TERMS
TermDefinition
Monitor descriptionDescription of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details).
Related DTCsDiagnostic code
Typical enabling condition
Preconditions that allow the ECM to detect malfunctions.
With all preconditions satisfied, the ECM sets the DTC when the monitored value(s) exceeds the malfunction
threshold(s).
Sequence of operation
The priority order that is applied to monitoring, if multiple sensors and components are used to detect the malfunc-
tion.
When a sensor is being monitored, the next sensor or component will not be monitored until the sensor monitoring
is finished.
Required sensor/compo-
nentsThe sensors and components that are used by the ECM to detect malfunctions.
Frequency of operation
The number of times that the ECM checks for malfunctions per driving cycle.
ºOnce per driving cycleº means that the ECM detects the malfunction only one time during a single driving cycle.
ºContinuousº means that the ECM detects malfunction every time an enabling condition is met.
DurationThe minimum time that the ECM must sense a continuous deviation in the monitored value(s) before setting a
DTC. This timing begins after the ºtypical enabling conditionsº are met.
Malfunction thresholdsBeyond this value, the ECM will conclude that there is a malfunction and set a DTC.
MIL operation
MIL illumination timing after a defect is detected.
ºImmediatelyº means that the ECM illuminates MIL the instant the ECM determines that there is a malfunction.
º2 driving cycleº means that the ECM illuminates MIL if the same malfunction is detected again in the 2nd driving
cycle.
