| Description of the problem | During cold weather, the 2. 0 turbo sonata engine will cut power to the car and go into a "limp" mode if an over boost code (usually p0605 & p2110 ), is triggered. This causes an unsafe situation as there is very little power available to get out of the way or can cause a rear vehicle crash. There have been a couple times where this has happened on 0 degree days or even at 30 degrees. This will happen at any speed if the boost pressure is exceeded and makes for a very dangerous situation. The ecu should not be cutting power or fuel, it should be reducing the boost to compensate for temperature. The only way to restore the power to the engine, is to shut the car off and restart..... Codes will still be active but the power will restore itself. |
