Dodge Stratus 2.0L Engine Code P1128: Causes and Solutions for O2 Sensor Issues

Model: Dodge Stratus Fault Code: P1128 Posted: 2008-07-03 17:26

Hi everyone, I'm looking for help identifying the cause of a P1128 diagnostic code on my Dodge Stratus with less than 30,000 miles. After some research, I believe it may be related to the oxygen (O2) sensor, but I'm having trouble locating the exact sensor location or understanding how to diagnose it properly. What are common causes of P1128 in this model? Are there specific troubleshooting steps or recommended actions I should take before visiting a mechanic? Any insights would be greatly appreciated.
