F2-91flowchartVRIS (Variable Resonance Induction System) — applies to the K8-ZE V6 engine intake.
Code No. 41 (VRIS Solenoid Valve No.1)
1
STEP 1: Disconnect connector from ECM; is there battery positive voltage at ECM terminal 3I with ignition switch ON?
Yes
Check ECM terminal connector for poor connection. If OK, replace ECM (see page F2-141); if not OK, repair or replace connector
No
2
STEP 2: In same condition as step 1, is there battery positive voltage at VRIS solenoid valve No.1 connector terminal A?
Yes
Repair or replace wire
No
3
STEP 3: Is VRIS solenoid valve No.1 OK? (see page F2-103)
No
Replace VRIS solenoid valve No.1
Yes
Look for a short or open circuit in wiring from main relay to solenoid valve
Code No. 46 (VRIS Solenoid Valve No.2)
1
STEP 1: Disconnect connector from ECM; is there battery positive voltage at ECM terminal 3J with ignition switch ON?
Yes
Check ECM terminal connector for poor connection. If OK, replace ECM (see page F2-141); if not OK, repair or replace connector
No
2
STEP 2: In same condition as step 1, is there battery positive voltage at VRIS solenoid valve No.2 connector terminal A?
Yes
Repair or replace wire
No
3
STEP 3: Is VRIS solenoid valve No.2 OK? (see page F2-103)
No
Replace VRIS solenoid valve No.2
Yes
Look for a short or open circuit in wiring from main relay (FUEL INJ relay) to solenoid valve
