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?
YES Go to Step 2.
Replace the injector with a new one.
NO
(!Page 111)
6) After repairing the trouble, clear the DTC using SDS tool.
(!Page 42)
Step 2
1) Turn the ignition switch ON.
2) Measure the injector voltage between Y/R wire and ground.
" Injector voltage: Battery voltage
NOTE:
Injector voltage can be detected only 3 seconds after ignition
switch is turned ON.
# 09900-25008: Multi-circuit tester set
* Tester knob indication: Voltage (+)
Is the voltage OK?
• Gr/B wire open or shorted to ground, or poor a
connection.
(Front cylinder side)
• Gr/W wire open or shorted to ground, or poor ^
connection.
(Rear cylinder side)
YES
• 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.
NO Open circuit in the Y/R wire.
3) After repairing the trouble, clear the DTC using SDS tool.
