Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

This seem to be a wiring problem. It codes out to be low voltage form No 2 O2 sensor. Once the car is ran local for approx 5 mile lite out no code.Just had the yearly emission and it passed but the day before the lite is lit. Have purchased a new o2 sensor but the wiring is real brittle and a little afraid of the night mare that lies ahead
