I have a ford taraus 1996 with 70,000 miles on it. My check engine light is on. I ran my reader and it came back with code 0156 which is a o2 sensor bank 2. Where is this sensor and what does bank 2 mean. Is this sensor an upstream or downstream sensor and what is the difference. I rather fix it my self then to take it to a mechanic. Thanks for all the help!
have the same problem?
