Sometimes after tc install this happens. You might have to have the code deleated and then have the test removed from your computer. What year is your car?

Usually this code is found when a tc with a stall of 3200 or higher. Like I said that you might need to clear this code and then have the test for this code deleated. Did this start after the tc was installed? You will need to see a tuner to fix your problem and have him do as I said. I believe this will fix your problem. Good luck, Vince.
