Hi All - I hope someone can explain this to me in simplified English. I would love to know if any of these issues could be resolved on the cheap, without bringing the car to the dealer and spending a boatload. Got a small neighborhood mechanic to take a look and he read the following codes: 17511-P1103 B1S1 - I googled this, and came up with a sensor heating circuit - but what does that mean and how can I fix that? 17544-P1136 B1 - this came up as a Fuel Trim issue... again, what does that mean in layman's terms and is there an easy fix? 16891-P0507 - Idle Air Control issue..... any easy fixes? 16395-P0011 A. B1 - Something about a Camshaft A.... Another issue which came up recently - the Traction Control light comes on and stays on at times. Sometimes it's nothing but the light, and sometimes I can feel the wheels slipping - various road conditions - wet, dry, uphill, downhill, flat... If the light is on and I hit the brakes, I sometimes feel a strong vibration under my feet. So, with this in mind, should I just bite the bullet and take it in or is there something I can do to remedy any of these issues? I don't mind getting dirty, I just don't know much about it yet, and haven't really worked on engines myself. Willing to give it a try though! Thanks guys - I appreciate you taking your time to help a newbie!
