terminals A and B (part-side).
• Is resistance within 4—
5k
i2 ?
Yes
Go to next step.
No
Replace IAC valve, then go to Step 14.
5
CLASSIFY MALFUNCTION AT POWER
SUPPLY CIRCUIT OR CONTROL CIRCUIT
• Turn ignition key to ON (Engine OFF).
• Measure voltage between IAC valve terminal
A (harness-side) and body ground.
• Is voltage B+?
Yes

No
Go to next step.
7
INSPECT POWER CIRCUIT FOR SHORT TO
GROUND
• Turn ignition key to OFF.
• Check continuity between IAC valve terminal
A (harness-side) and body ground.
• Is there any continuity?
Yes
Repair or replace harness, then go to Step 14.
No
Go to next step.
8
INSPECT POWER CIRCUIT FOR OPEN
• Turn ignition key to OFF
• Check continuity between IAC valve terminal
A (harness-side) and PCM terminal 54.

No
Go to next step.
10
INSPECT CONTROL CIRCUIT FOR SHORT TO
POWER
• Turn ignition key to ON (Engine OFF).
• Measure voltage between IAC valve terminal
B (harness-side) and body ground.
• Is voltage
B+?
Yes
Repair or replace harness, then go to Step 14.
No
Go to next step.
11
INSPECT CONTROL CIRCUIT FOR SHORT TO
GROUND
• Turn ignition key to OFF.
• Check continuity between IAC valve terminal
B (harness-side) and body ground.
• Is there any continuity?
Yes
Repair or replace harness, then go to Step 14.
No
Go to next step.
12
INSPECT CONTROL CIRCUIT MALFUNCTION
FOR OPEN
• Check continuity between IAC valve terminal
B (harness-side) and PCM terminal 83.
• Is there any continuity?
Yes
Repair or replace harness, then go to next step.
No
Go to next step.
