Summary
TSB: Some 2012 ? 2015 model year Sequoia and Tundra vehicles with the 3UR-FBE engine may exhibit a MIL ?ON? condition with Diagnostic Trouble Codes (DTCs) P0171/P0174 (System too Lean Bank 1/Bank 2), P0172/P0175 (System too Rich Bank 1/Bank 2), P1604 (Startability Malfunction), and/or P1605 (Rough Idling) after attempting to start the engine. Alcohol Density Estimate values may be high even though the vehicle was fueled with regular fuel (E0/E10). The Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM) logic has been modified to address this condition. Use the following Repair Procedure to reprogram the ECM (PCM).
