3) Check the IAP sensor coupler (Front cylinder side
1
or Rear
cylinder side
2
) for loose or poor contacts.
If OK, then measure the IAP sensor input voltage.
4) Disconnect the IAP sensor coupler.
5) Turn the ignition switch ON.
6) Measure the voltage at the Red wire
3
and ground.
7) Also, measure the voltage at the Red wire
3
and B/Br wire
4

Step 2
1) Connect the IAP sensor coupler.
2) Insert the needle pointed probes to the lead wire coupler.
3) Start the engine at idle speed and measure the IAP sensor
output voltage at the wire side coupler.

YES Go to Step 2.
NO
• Loose or poor contacts on the ECM coupler
(terminal
5
or
B
).
• Open or short circuit in the Red wire or B/Br
wire.
YES Go to Step 3.
NO
• Check the vacuum hose for crack or damage.
• Open or short circuit in the G/B wire.
(Front cylinder side)
• Open or short circuit in the G/Y wire.
(Rear cylinder side)
• If vacuum hose and wire are OK, replace the
IAP sensor with a new one.
