SERVICE INFORMATION If a 2000 to 2002 G20 has a MIL “On” and any of the following DTCs stored in the ECM: • P0138 Heated Oxygen Sensor 2 (Rear) (Bank 1) (Max. Voltage Monitoring) • P0139 Heated Oxygen Sensor 2 (Rear) (Bank 1) (Response Monitoring) •
P0140 Heated Oxygen Sensor 2 (Rear) (Bank 1) (High Voltage) Start with the Service Procedure to find out if the bulletin applies to this vehicle. If it does apply, complete the Service Procedure to repair the incident, if it should occur.
You will be performing the following, as required:

Use this procedure to check the overall function of the heated oxygen sensor 2 (rear) circuit. During this check, a 1st trip DTC might not be confirmed. WITH GST 1. Start engine and drive vehicle at a speed of more than 70 km/h (43 MPH) for 2
consecutive minutes . 2. Stop vehicle with engine running. Zoom Sized for Print 3. Set voltmeter probes between ECM terminal 72 [HO2S2 (B1) signal] or 71 [HO2S2 (B2) signal] and engine ground. 4. Check the voltage when racing up to 4,000 rpm under no load at least 10 times. (Depress and release accelerator pedal as soon as possible.) The voltage should be above 0.56 V at least once during this procedure. If the voltage can be confirmed
in step 4, step 5 is not necessary.

Component Description The heated oxygen sensor 2 (rear), after three way catalyst (Manifold), monitors the oxygen level in the exhaust gas on each bank. Even if switching characteristics of the heated oxygen sensor 1 (front) are shifted, the air fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2 (rear). this sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1 V in richer conditions to 0 V in leaner conditions. Under normal conditions the heated oxygen sensor 2 (rear) is not used for engine control

REMOVAL 1) Remove front wheels. 2) Remove air intake duct. Zoom Sized for Print 3) Disconnect connector from front oxygen sensor. 4) Disconnect connector from rear oxygen sensor, (California 2200 cc model only) 5) Remove pitching stopper. 6) Remove radiator upper brackets, 7) Support engine with a lifting device and wire ropes.
8) Lift-up the vehicle.
