IGNITION TIMING INSPECTION
1.
(see step 2 on HOW TO USE THE HDS (HONDA DIAGNOSTIC
SYSTEM) ), and check for DTCs. If a DTC is present, diagnose and repair the
cause before inspecting the ignition timing.
2. Start the engine. Hold the engine speed at 3,000 RPM without load (in Park or
neutral) until the radiator fan comes on, then let it idle.
3. Check the idle speed (see IDLE SPEED ADJUSTMENT ).
4. Jump the SCS line with the HDS.
Aim the light toward the pointer (A) on the oil pump. Check the ignition timing

UPDATING AND SUBSTITUTION FOR TESTING-2002-2006 M/T
MODELS AND CVT MODEL ), or substitute a known-good ECM 2000-
2001 M/T models (see HOW TO SUBSTITUTE THE ECM FOR
TESTING PURPOSES-2000-2001 M/T MODELS ), 2002-2006 M/T

Is there battery voltage?
YES -Go to step 3.
NO -Repair an open in the wire between the ignition coil and the No. 7
(15 A) fuse in the under-dash fuse/relay box.
3. Turn the ignition switch OFF.
4. Check for continuity between each ignition coil 3P connector terminal No. 2

Is there about 0.5 V?
YES -Replace the ignition coil.
NO -Repair an open in the wire between the ignition coil and the ECM.
SPARK PLUG INSPECTION/REPLACEMENT
1. Remove the spark plugs, and note which cylinder each one came from.
2. Inspect the electrodes and ceramic insulator.
Burned or worn electrodes may be caused by:
Advanced ignition timing
Loose spark plug
Insufficient cooling
Fouled plug may be caused by:
Retarded ignition timing
Oil in combustion chamber
Incorrect spark plug gap
Excessive idling/low speed running
Clogged air cleaner element
Use a chemical cleaner such as Carb Spray to clean

3. If the spark plug electrode is dirty or contaminated, clean the electrode with a
plug cleaner.
NOTE:
Do not use a wire brush or scrape the iridium
electrode since this will damage the electrode.
Do not adjust the gap (A) on iridium tip plugs; replace the spark plug if the gap

When using a sand blaster spark plug cleaner, do
not clean for more than 20 seconds to avoid
damaging the electrode.

7. Apply a small amount of anti-seize compound to the plug threads, and screw
the plugs into the cylinder head, finger-tight. Torque them to 23 N.m (2.3

NOTE: If a spark plug is to be reused, use it in the cylinder
where the plug was originally located.
INTEGRATED MOTOR ASSIST (IMA) SYSTEM (IF ENGINE MAINTENANCE IS REQUIRED)
IMA components are located in this area. The IMA is a high-voltage system. The
high voltage cables and their covers are identified by orange coloring. The safety
labels are attached to high voltage and other related parts (see
DANGER/WARNING/CAUTION LABEL LOCATIONS ). You must be
familiar with the IMA system before working on or around it. Make sure you have
read the Service Precautions in the IMA section before performing repairs or
SERVICE PRECAUTIONS
