Before you begin, allow engine to cool down. Spray down all bolts & nuts with WD-40 (or similar) and allow it to soak into the threads. The nuts & bolts will seize themselves onto the threads and spaying them down with Liquid Wrench or similar will make it much easier to remove the nuts & bolts.
- Test pipes laid out & test pipes laid out w/ additional wide band O2 ports.
- Close up detail of mechanical O2 sensor fix
- Remove 3 14mm nuts at exhaust manifold/catalytic converter flange. There are three nuts holding the catalytic converter to the exhaust manifold. Two nuts are facing the ground on one side of the flange, the third nut is on the opposite side of the flange. Use a 14mm stubby wrench or “S” wrench to remove the third nut. Repeat for other side.

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.

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).
