P0140 Oxygen Sensor Not Detected - 1996 Dodge Grand Caravan Diagnosis and Repair Advice
I recently purchased a 1996 Dodge Grand Caravan that requires several repairs, including brake pads and rotors, as well as replacement of the ECM/PCM. The vehicle has consistently been displaying the P0140 trouble code, which indicates an oxygen sensor not detected. I'm seeking clarification on whether replacing the oxygen sensor is essential for the vehicle's performance or if it can be safely ignored without causing further damage. As a full-time college student with limited funds, I want to ensure this repair is both necessary and cost-effective before proceeding. Any insights into the importance of this code and recommended next steps would be greatly appreciated. Thanks, Cheryl.
It's advisable to replace the oxygen sensor with a new NTK brand O2 sensor or have it professionally installed by someone experienced with 1996 Dodge Grand Caravan models. Additionally, consider investigating why the ECM/PCM was replaced in the first place, as this could impact the accuracy of the P0140 code and overall engine performance.
