Without CONSULT-III
- Start engine and warm it up to the normal operating temperature.
- Turn ignition switch OFF and wait at least 10 seconds.
- Start engine and keep the engine speed between 3,500 and 4,000 RPM for at least 1 minute under no load.
- Let engine idle for 1 minute.
- Open engine hood.
- Check the voltage between ECM harness connector terminals under the following condition.
VOLTAGE REFERENCE CHART
| ECM | ECM | Condition | Voltage | ||
|---|---|---|---|---|---|
| Connector | Terminal | Connector | Terminal | ||
| F8 | 33 (HO2S2 signal) | F8 | 35 (Sensor ground) | Keeping engine speed at 2,500 RPM constant under no load | The voltage fluctuation cycle takes more than 5 seconds. 1 cycle: 0.6 - 1.0 → 0 - 0.3 → 0.6 - 1.0 |
Is the inspection result normal?
