Right after the catalytic converter
02 sensor circuit slow response bank (bank 1 sensor 1)
There are two in the exhaust system on the rear of the engine.
Rear of engine, upper part of exhaust system.
P0140 code means the rear 02 sensor behind the catalytic convertor has an open circuit. It says no communication from the rear 02 sensor. The rear 02 sensor is also called sensor 2, whether it be bank 1 or bank 2. Hope this helps.
Bank 1 is the driver side.
