Alright, so I've been apart of this forum and have found a lot of useful information. The other day I had to get the car (my 2001 Insight) in for emissions. Lo and behold my surprise when they said that my little car failed with an error code of P1169. I know that it means the A/F sensor is reading high voltage I'm confused weather that means the o2 sensor is bad or if the A/F sensor is bad. Can someone please explain the difference and how I can diagnose the difference to get it fixed. I need to fix it asap and get it in to pass emissions soon. Please Help. Thanks for your time.
