Chrysler Repair: O2 Sensor 1997 Chrysler Sebring 2.5, chrysler sebring, haynes manual


Question
I have a 1997 Chrysler Sebring 2.5. I'm getting an engine code P0140, which is an O2 sensor. The problem is, which one. The explanation says, PCM determined insufficient activity from Oxygen sensor 2 on bank 1. Looking at the underside of the veh. there are 3 sensors within 2 feet of each other, one on each manifold and one in between. I have a haynes manual which only talks about upstream and downstream, can you tell the exact location of this specific O2 sensor. Thanks.

Answer
Hi Eric,
There are I believe 3 sensors, two before the catalytic converter and one after it. The 1/2 sensor is the one AFTER the catalytic converter, i.e. downstream from the front two sensors. It by chance there are two downstream sensors it would be the one that comes from the right side of the engine, but I believe there is only one after the converter.
