3) Disconnect the IAP sensor coupler.
4) Turn the ignition switch ON.
5) Measure the voltage at the R wire and ground.
6) If OK, then measure the voltage at the R wire and B/Br wire.
IAP sensor input voltage: 4.5 – 5.5 V
(+ R – - Ground)
(+ R – - B/Br)
09900-25008: Multi-circuit tester set
Tester knob indication: Voltage ()
Is the voltage OK?
Step 1 (When indicating P0105-H:)
1) Turn the ignition switch OFF.
2) Check the IAP sensor coupler 1 for loose or poor contacts.
If OK, then check the IAP sensor lead wire continuity.
3) Disconnect the IAP sensor coupler.
4) Check the continuity between R wire and G/B wire.
If the sound is not heard from the tester, the circuit condition
is OK.
YES Go to Step 2.
NO
• Loose or poor contacts on the ECM coupler
(terminal 9 or 4).
• Open or short circuit in the R wire or B/Br wire.
