New to site and was researching what to do when I get indicator light on and only go 40 mph. I found out how to get code, what code was and suggestions to fix. Great information on this site and plan to use more. Code was 340 and realize in safe mode car is stuck in second gear-scared the #*@% out of me and kids when it started lurching. I disconnected battery neg to clear code and so far so good. Even know where sensor is to change if I need to in future. Hopefully that is the cure -was dreading how much the bill was going to be when I bring in for check. Now on to dash light replacements (sounds like a nightmare) and front end squeaks. Again, great info on this forum.
Well code returned after a couple weeks and went ahead and changed sensor. Hope that is the cure. The info on how to change was great-even I (a non mechanic) was able to do. Only hold up was how to unclip-the little orange piece slides out then pry connector plug from sensor.
