DTC DETECTION LOGIC
To judge malfunctions, this diagnosis measures response time of the A/F signal computed by ECM from the A/
F sensor 1 signal. The time is compensated by engi ne operating (speed and load), fuel feedback control con-
stant, and the A/F sensor 1 temperature index. Judgment is based on whether the compensated time (the A/F
signal cycling time index) is inordinately long or not.
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.

3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
Do you have CONSULT?
YES >> GO TO 2.
NO >> GO TO 6.
2.PERFORM DTC CONFIRMATION PROCEDURE-1
With CONSULT
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Turn ignition switch ON.
4. Turn ignition switch OFF and wait at least 10 seconds.
5. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1minute under no load.
6. Let engine idle for 1 minute.
7. Increase the engine speed up to about 3,600 rpm and keep it for 10 seconds.
8. Fully release accelerator pedal and then let engine idle for about 1 minute.
9. Check the items status of “DATA MONITOR” as follows.

• Do not use a wire brush for cleaning the spark plugs. Replace as
necessary.
• If plug is covered with carbon, a spark plug cleaner may be used.
• Checking and adjusting plug gap is not required between change intervals. If the gap is out of s pecification, replace the spark plug.
CAUTION:
Do not drop or shock plug.
INSTALLATION
Installation is in the reverse order of removal.
*: Always check with the Parts Department for the latest parts information.
CAUTION:
Always tighten the spark plug to sp ecified torque to align the orientation of electrodes. The ground
electrode of a genuine spark plug is positioned in the area of maximum ignitability by tightening to the
specified torque. When replacing spark plugs, use genuine spark plugs of which the ground electrode
is adjusted.

(starting, idling, and/or noise).
1. Remove the fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Removal and
Installation".
2. Remove the rocker cover using power tool. Refer to EM-45, "Removal and Installation"

3. Turn crankshaft pulley clockwise when viewed from front to align TDC identification mark (B) with timing indicator (A).
NOTE:
Do not confuse TDC mark (B) with paint marks (C).
4. At this time, check that the both intake and exhaust cam lobes of No. 1 cylinder face outside.
• If they do not face outside, turn crankshaft pulley once more.
5. Measure valve clearances with a feeler gauge at locations marked (X) in the table below.
