2003 Mitsubishi Carisma P0032 Code: Oxygen Sensor Error in Diesel Model?

Model: 2003 Mitsubishi Carisma Fault Code: P0032 Posted: 2017-02-26 16:15

Hello, I recently noticed a yellow warning light on my 2003 Mitsubishi Carisma diesel model. This issue started after I had a new turbocharger installed. Using an OBD2 code reader, I received the diagnostic trouble code P0032, which is typically interpreted as a faulty oxygen sensor for Bank 1 Sensor 1. I've searched extensively online and found that P0032 generally refers to an oxygen sensor failure in gasoline engines. However, my Carisma is a diesel vehicle, and diesel engines do not use oxygen sensors — they rely on different emissions control systems. This has led me to question: why does the scanner show a faulty oxygen sensor when my car doesn't have one? Are there any known compatibility issues with turbo installations in diesel models? I attempted to purchase an oxygen sensor for replacement, but none are available for diesel vehicles. Is this code a misdiagnosis, or is there another underlying issue I should investigate? Any insights from owners of 2003 Mitsubishi Carisma diesel models would be greatly appreciated.
