1997 Chrysler LHS P0134: Oxygen Sensor Circuit No Activity Detected - Location and Diagnosis
I own a 1997 Chrysler LHS with a 3.5L engine. Recently, my check engine light came on. After checking the code using both key-on/key-off and OBD2 scan tool procedures, I received a P0134 diagnostic trouble code: 'Oxygen Sensor Circuit No Activity Detected - Bank 1, Sensor 1'. My question is: Where exactly is Bank 1, Sensor 1 located on this vehicle? I understand that the oxygen sensor is part of the exhaust system, but I need clarification on its position relative to the engine and exhaust manifold. I'm looking for accurate technical details so I can properly diagnose or replace the sensor if needed.
Bank 1, Sensor 1 is located on the passenger side of the vehicle, specifically at the first oxygen sensor downstream from the exhaust manifold. This is typically referred to as the first oxygen sensor in the sequence when counting from the exhaust manifold toward the tailpipe. It's important to confirm this position during inspection or replacement to ensure correct diagnosis and repair.
