FI SYSTEM DIAGNOSIS 5-69
5) If OK, then check the continuity between each terminal and
ground.
$ STP sensor continuity: ∞ Ω (Infinity)
! 09900-25008: Multi-circuit tester set
% Tester knob indication: Resistance (Ω)
Are the resistance and continuity OK?
6) After repairing the trouble, clear the DTC using SDS tool.
(#5-26)
Step 2
1) Turn the ignition switch ON.
2) Measure the injector voltage between Y/R wire and ground.
$ Injector voltage: Battery voltage
(+ Y/R – - Ground)
NOTE:
Injector voltage can be detected only 3 for seconds after ignition
switch is turned ON.
! 09900-25008: Multi-circuit tester set
& Tester knob indication: Voltage (')
Is the voltage OK?
3) After repairing the trouble, clear the DTC using SDS tool.
(#5-26)
YES Go to Step 2.
NO Replace the injector with a new one. (#6-22)
YES
• Gr/B wire open or shorted to ground, or poor g
connection.
(Front cylinder side)
• Gr/W wire open or shorted to ground, or poor h
connection.
(Rear cylinder side)
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
