Bank 1 is the same side as cylinder #1.
Sensor 2 is after the catalytic converter.
P0139 02 Sensor Circuit Slow Response (Bank 1 Sensor 2)P0139 02 Sensor Circuit Slow Response (Bank 1 Sensor 2)
Bank 1 (one) is the side in front of car (Bank 2 is rear, firewall side) 02 sensor 1 is upstream, on exhaust manifold (02 sensor 2 is downstream, by cat. conv.)
Bank one is the side of the engine with cylinder #1. Sensor two is after the catalytic converter.
Bank one is the side of the engine with cylinder #1. Sensor two is after the catalytic converter.
well bank 2 is passenger side of engine and sensor 2 is second one. 02 sensors on 2005 avanlache have 4 02 sensors 2 pre on bank 1 and 2 and have post on bank 1 and 2
Bank one is the side of the engine with cylinder #1. Sensor two is after the catalytic converter.
before the cat , at the manifold
That would be the sensor after the catalytic converter.
That is the sensor in the catalytic converter.
Bank 2 locates on the opposite side of the cylinder # 1 and the sensor 1 is locates in the front
Bank 2 is the right side of the motor if sitting in the seat and sensor 1 is the first 02 sensor that is in the exhaust manifold.
