EC-206 < COMPONENT DIAGNOSIS > [VQ35HR] P0137, P0157 HO2S2 6. Select “FUEL INJECTION” in “ACTIVE TEST” mode, and select “HO2S2 (B1)/(B2)” as the monitor item 7. Check “HO2S2 (B1)/(B2)” at idle speed when adjusting “FUEL INJECTION” to ± 25%. “HO2S2 (B1)/(B2)” should be above 0.68V at least once when the “FUEL INJECTION” is +25%. − 25%. Is the inspection result normal? YES >> INSPECTION END NO >> GO TO 6. 3. CHECK HEATED OXYGEN SENSOR 2-I Without CONSULT-III 1. Start engine and warm it up to the normal operating temperature. 2. Turn ignition switch OFF and wait at least 10 seconds. 3. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load. 4. Let engine idle for 1 minute. 5. Check the voltage between ECM harness connector and ground under the following condition. Is the inspection result normal? YES >> INSPECTION END NO >> GO TO 4. 4. CHECK HEATED OXYGEN SENSOR 2-II Check the voltage between ECM harness connector and ground under the following condition. Is the inspection result normal? YES >> INSPECTION END NO >> GO TO 5. 5. CHECK HEATED OXYGEN SENSOR 2-III Check the voltage between ECM harness connector and ground under the following condition. PBIB3458E ECM Ground Condition Voltage Connector Terminal F102 76 [HO2S2 (bank 1)] Ground Revving up to 4,000 rpm under no load at The voltage should be above 0.68V at 80 [HO2S2 (bank 2)] ECM Ground Condition Voltage Connector Terminal F102 76 [HO2S2 (bank 1)] Ground Keeping engine at idle for 10 minutes The voltage should be above 0.68V at 80 [HO2S2 (bank 2)] |
