Service bulletin T-SB-0206-12

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2012 and 2013 model year Sequoia and Tundra vehicles with the 3UR-FBE (5.7 L) engine may exhibit a MIL ?ON? condition with Diagnostic Trouble Code (DTC) P0461 (Fuel Level Sensor ?A? Circuit Range/Performance) after a recent fuel refill. The Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM) logic has been revised to address this condition. Use the following repair procedure to recalibrate the ECM (PCM).

D0E_LSC_Technica	2017-08-14. Service bulletin. Technical Instructions: In certain 2012 - 2013 Model Year Toyota Tundra and Sequoia vehicles equipped with a 5.7 Liter gasoline or 5.7 Liter-Flex Fuel engines, the Engine Control Module (ECM) calibration may cause an emissions control component called an Air Injection Pump to fail under certain driving conditions. If this occurs, the vehicle could enter a "Fail-Safe" Mode (also known as "Limp-Home" Mode). This mode reduces the vehicle's power and speed, which could inconvenience you and require immediate repair.
F0A_LSC_Region L	2017-08-14. Service bulletin. Region Letter: In certain 2012 - 2014 Model Year Toyota Tundra and Sequoia vehicles equipped with a 5.7 Liter gasoline or 5.7 Liter-Flex Fuel engines, the Engine Control Module (ECM) may set a Diagnostic Trouble Code (DTC) if debris/ice becomes lodged in the air switching valve. If this occurs, the Malfunction Indicator (Check Engine) Light could illuminate and the vehicle could enter a "Fail-Safe" Mode (also known as "Limp-Home" Mode). If this occurs the vehicle's power and speed will be reduced, which could inconvenience you and require immediate repair.
