5-40 FI SYSTEM DIAGNOSIS
Step 2
1) Connect the IAP sensor coupler and ECM coupler.
2) Reinstall the fuel tank and lift up the fuel tank.
3) Insert the needle pointed probes to the lead wire coupler.
4) Start the engine at idle speed and measure the IAP sensor
output voltage at the wire side coupler.
(#2: between P/B and B/Br wires)
(#1: between G/B and B/Br wires)
$ IAP sensor output voltage:
Approx. 1.4 – 3.8 V at idle speed
(#2: + P/B – - B/Br)
(#1: + G/B – - B/Br)
! 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
& Tester knob indication: Voltage (')
Is the voltage OK?
5) After repairing the trouble, clear the DTC using SDS tool.
(#5-26)
Step 3 (#5-36)
Output voltage (VCC voltage 4.5 – 5.0 V, ambient temp. 20 –
30 °C, 68 – 86 °F)
YES Go to Step 3.
NO
• Check the vacuum hose for crack or damage.
• Open or short circuit in the P/B wire. (#2)
• Open or short circuit in the G/B wire. (#1)
• If vacuum hose and wire are OK, replace the
IAP sensor with a new one.
