2. Turn the ignition switch ON (II).

3. Make sure the HDS communicates with the ECM/PCM. If it doesn't, go to the DLC circuit

troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).

4. Select the INSPECTION MENU with the HDS.

5. Do the TP LEARNING CHECK in the ETCS TEST. If needed, clean the throttle body (see THROTTLE

BODY CLEANING ).

THROTTLE BODY CLEANING

1. Check for damage to the air cleaner. If the air cleaner is damaged, replace it (see AIR CLEANER

REMOVAL/INSTALLATION ).

2. Remove the throttle body (see THROTTLE BODY REMOVAL/INSTALLATION ).

3. Clean off the carbon from the throttle valve and inside the throttle body with a paper towel soaked in

throttle plate and induction cleaner.

CAUTION: Do not insert your fingers into the installed throttle body when you turn

the ignition switch ON (II) or while the ignition switch is ON (II). If you do,
you will seriously injure your fingers if the throttle valve is activated.

NOTE:



Remove the throttle body to clean it.



Be careful not to pinch your fingers.



To avoid removing the molybdenum coating, do not clean the bearing
area of the throttle shaft (A).



Do not spray throttle plate and induction cleaner directly on the
throttle body.



Use Honda genuine throttle plate and induction cleaner.

4. Install the throttle body (see THROTTLE BODY REMOVAL/INSTALLATION ).

5. Reset the ECM/PCM with the HDS (see ECM/PCM RESET ).

6. Turn the ignition switch ON (II), and wait 2 seconds.

7. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

INTAKE AIR BYPASS CONTROL THERMAL VALVE TEST

Special Tools Required

Vacuum pump/gauge, 0-30 in.Hg, Snap-on YA4000A or equivalent, commercially available

1. Start the engine, and let it idle.

2. Remove the vacuum hose (A) from the intake air duct, and connect a vacuum pump/gauge, 0-30 in.Hg, to

the hose.

NOTE:

The engine coolant temperature must be below 131°F (55°C).

3. Raise and lower the engine speed, making sure the vacuum gauge reading changes as the engine speed

changes.

If the vacuum reading does not change, check for these problems:



Misrouted, leaking, broken, or clogged intake air bypass control system vacuum lines.



A cracked or damaged intake air bypass control thermal valve. Replace the valve if needed (see
RESONATOR REMOVAL/INSTALLATION ).

4. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on, then

let it idle.

5. Raise and lower the engine speed, making sure the vacuum pump/gauge reading does not indicate any

vacuum as the rpm changes.

If there is a vacuum reading, check for these problems:



Misrouted, leaking, broken, or clogged intake air bypass control system vacuum lines.



A cracked or damaged intake air bypass control thermal valve. Replace the valve if needed (see
RESONATOR REMOVAL/INSTALLATION ).

THROTTLE BODY REMOVAL/INSTALLATION

1. Connect the HDS to the DLC while the engine is stopped.

2. Select the INSPECTION MENU on the HDS.

3. Do the TP POSITION CHECK in the ETCS TEST.

4. Turn the ignition switch OFF.

5. Remove the intake air duct (A).

CAUTION: Do not insert your fingers into the installed throttle body when you turn

the ignition switch ON (II) or while the ignition switch is ON (II). If you do,
you will seriously injure your fingers if the throttle valve is activated.

NOTE:

If you are replacing or cleaning the throttle body, start at step 1. If you are
removing the throttle body, start at step 4.

6. Disconnect the throttle body connector (B).

7. Disconnect and plug the water bypass hoses (C).

8. Remove the throttle body (D).

9. Install the parts in the reverse order of removal with a new gasket (E).

ACCELERATOR PEDAL REPLACEMENT

1. Remove the throttle cable (A) from the accelerator pedal (B) (see THROTTLE CABLE

REMOVAL/INSTALLATION ).

NOTE:



Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN
PROCEDURE ) after the throttle body has been replaced.



Refill the radiator with engine coolant (see COOLANT CHECK ).
