4-60 FI SYSTEM DIAGNOSIS
7) Disconnect the ECM coupler.
8) Check the continuity between R wire
9) If OK, then check the continuity between G/Y wire
minal .
APS lead wire continuity: Continuity (?)
\ 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
= Tester knob indication: Continuity test (?)
Is the continuity OK?
YES Go to Step 1 ( 4-57) and go to Step 2.
NO R or G/Y wire open, or G/Y wire shorted to ground
10)After repairing the trouble, clear the DTC using SDS tool.
( 4-28)
Step 2
1) Connect the AP sensor coupler and ECM coupler.
2) Insert the needle pointed probes to the lead wire coupler.
Turn the ignition switch ON.
3) Measure the AP sensor output voltage at the wire side cou-
pler (between G/Y and B/Br wires).
AP sensor output voltage: Approx. 2.6 V at
\ 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
W Tester knob indication: Voltage ()
YES Go to Step 3.
• Check the air passage for clogging.
NO • Open or short circuit in the G/Y wire
• Replace the AP sensor with a new one.
4) After repairing the trouble, clear the DTC using SDS tool.
