VEHICLE SPEED (km/h, mph)
It is computed based on pulse signals from front wheel
speed sensor (RH, LH) (for M/T model) or output shaft
speed sensor (VSS) (for A/T model).INJ PULSE WIDTH (FUEL INJECTION PULSE WIDTH,
msec.)
This parameter indicates time of the injector drive (valve
opening) pulse which is output from ECM (but injector
drive time of NO.1 cylinder for multiport fuel injection).

Repair Instructions
Idle Speed and IAC Throttle Valve Opening
Inspection
S6RW0D1106001
Before idle speed check, make sure of the following.
• Lead wires and hoses of electronic fuel injection and
engine and emission control systems are connected
securely.
• Valve lash is checked according to maintenance
schedule.
• Ignition timing is within specification.
• All accessories (wipers, heater, lights, A/C, etc.) are
out of service.
• Air cleaner has been properly installed and is in good
condition.
• No abnormal air drawn in from air intake system.After all items are confirmed, check idle speed and IAC
throttle opening as follows.NOTE
Before starting engine, place transmission
gear shift lever in “Neutral”, and set parking
brake and block drive wheels.
Step Action Yes No
1Is there DTC(s) of ECT sensor circuit (DTC P0116 / P0117 /
P0118) and/or radiator cooling fan circuit (DTC P0480)?Go to corresponding
DTC flow.Go to Step 2.
2Radiator cooling fan control circuit check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Start engine and select “Data List” on scan tool.
3) Warm up engine until coolant temp. is 100 °C, 212 °F or
higher and A/C switch turns OFF (if equipped with A/C).
(If engine coolant temp. dose not rise, check engine
cooling system or ECT sensor.)
Is radiator cooling fan started when engine coolant temp.
reached above temp.?Radiator cooling fan
control system is in
good condition.Perform from Step 2 to
Step 7 in DTC P0480
diag. flow. If OK, Go to
Ste p 3.
3Radiator cooling fan control check
1) Disconnect radiator cooling fan motor connector with
ignition switch turned OFF.
2) Run engine when ECT is over 100 °C, 212 °F.
3) Measure voltage between vehicle body ground and
“BLU/RED” wire terminal of disconnected radiator
cooling fan motor connector.
Is voltage 10 – 14 V?Go to Step 4. “BLU/RED” wire is open
or high resistance
circuit.
4Check radiator cooling fan wire circuit check
1) Turn ignition switch to OFF position.
2) Measure resistance between “BLK” wire terminal of
disconnected radiator cooling fan motor connector and
vehicle body ground.
Is resistance below 1
Ω?Go to Step 5. “BLK” wire is open or
high resistance circuit.
5Radiator cooling fan check
1) Check radiator cooling fan referring to “Radiator Cooling
Fan Assembly On-Vehicle Inspection in Section 1F”.
Is it in good condition?Substitute a known-
good ECM and recheck.Faulty radiator cooling
fan.
