In a 2008 Toyota Tundra, if you encounter the C1201 code, it means there's a problem with the engine control system. This issue could stem from the fuel injection system or occur in conjunction with other codes, such as P0455 and P0441. These codes typically indicate an emission leak within the system, which could range from a minor issue like a loose fuel cap to a more significant evaporation leak. The C1201 code is designed to activate the Check Engine light and disable traction and vehicle stability control. To resolve this situation, you must address the underlying problems linked to the additional codes before attempting to clear the C1201 code.
The error code C1201 on the 2008 Toyota Tundra 5.7 indicates a malfunction in the engine control system.
