2005 Mitsubishi Galant Q&A
2005 Mitsubishi Galant Question: obdII codes
You are having connection problems between the diagnostic link and the scanner. You could have a blown fuse or wiring probs. You may also have a failed computer. - raiderron
Have an obdII diagnostic tool and it says that all four of my o2 sensors have failed. Service engine light is on. Is there a central point where there may be a bad connection?
