Where is the catalytic converter located on a 2001 Chevy Venture van?
A catalytic converter on a 2001 Chevy Venture van is located under the vehicle. Follow the exhaust pipe from the engine to the rear of the vehicle. The large object connected to the exhaust pipes between the engine, and the muffler at the rear, is your catalytic converter.
On GM, bank one is drivers side of engine, bank 2 is passengers side. Sensor(s) 1 is the upstream sensor, meaning BEFORE catalytic converter. Sensor(s) 2 are located downstream, or AFTER the catalytic converter, therefore, bank 2, sensor 2 is located in the exhaust pipe leading from the passenger side of engine and after the catalytic converter.
