- Using DRB-II, erase fault codes. Start engine. Run engine until coolant temperature reaches more than 160°F (71°C). Read O2 sensor voltage. If O2 sensor voltage is not a constant zero volts, go to step 3). If O2 sensor voltage is a constant zero volts, go to next step.
- Disconnect O2 sensor connector. If O2 sensor voltage is still a constant zero volts, repair White wire for a short to ground between ECU 24-pin connector terminal No. 4 and O2 sensor connector, and perform TEST VER-2. If O2 sensor voltage is not a constant zero volts, replace O2 sensor, and perform TEST VER-2.
- Recheck O2 sensor voltage. If O2 sensor voltage is not a constant .03 volts, replace O2 sensor, and perform TEST VER-2. If O2 sensor voltage is a constant .03 volts, disconnect O2 sensor connector. Connect a jumper wire between O2 sensor White wire and ground.
- If O2 sensor voltage is still a constant .03 volts, go to step 6). If O2 sensor voltage is not a constant .03 volts, turn ignition off. Measure resistance between O2 sensor Black wire and ground.
- If resistance is more than 10 ohms, repair open circuit in Black wire between ECU terminal No. 24 and O2 sensor, and perform TEST VER-2. If resistance is less than 10 ohms, replace O2 sensor, and perform TEST VER-2.
- Turn ignition off. Disconnect ECU 24-pin connector. Measure resistance of White wire between ECU connector terminal No. 4 and O2 sensor connector. If resistance is more than 10 ohms, repair open circuit in White wire between ECU 24-pin connector terminal No. 4 and O2 sensor connector, and perform TEST VER-2. If resistance is less than 10 ohms, replace ECU and perform VERIFICATION PROCEDURE VER-2.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
