AIR INDUCTION SYSTEM

CHECKING THE AIR INDUCTION SYSTEM

Air injection

The air induction system burns unburned 
exhaust gases by injecting fresh air (second-
ary air) into the exhaust port, reducing the 
emission of hydrocarbons. When there is neg-
ative pressure at the exhaust port, the reed 
valve opens, allowing secondary air to flow into 
the exhaust port. The required temperature for 
burning the unburned exhaust gases is 
approximately 600 to 700

°

C.

Air cut-off valve

The air cut-off valve is controlled by the signals 
from the ECU in accordance with the combus-
tion conditions. Ordinarily, the air cut-off valve 
opens to allow the air to flow during idle and 
closes to cut-off the flow when the vehicle is 
being driven. However, if the coolant tempera-
ture is below the specified value, the air cut-off 
valve remains open and allows the air to flow 
into the exhaust pipe until the temperature 
becomes higher than the specified value.

1. Check:

• Hoses

Loose connections 

→

 Connect properly.

Cracks/damage 

→

 Replace.

• Pipes

Cracks/damage 

→

 Replace.

2. Check:

• Reed valve “1”
• Reed valve stopper
• Reed valve seat

Cracks/damage 

→

 Replace the reed valve.

3. Measure:

• Reed valve bending limit “a”

Out of specification 

→

 Replace the reed 

valve.

4. Check:

• Air cut-off valve

Cracks/damage 

→

 Replace.

5. Check

• Air induction system solenoid

Refer to "CHECKING THE AIR INDUC-
TION SYSTEM SOLENOID" on page 8-98.

A. From the air cleaner
B. To the cylinder head

Reed valve bending limit
