Description
2004 Jeep Liberty displays o2 sensor heating malfunction. Replaced sensor x2. Don't know how to troubleshoot but think it is a wiring issue. Bank 1 sensor 1 and wiring is hard to work with. I am 74 years old and JEEP will fail emissions, need reasonable cost repairs. Really need Jeep skilled technician who works outside of dealership or shop at fair wage. Any suggestions welcome.
