ADDITIONAL INFORMATION
Introduction
Some 2012 - 2013 model year Sequoia and Tund ra vehicles with the 3UR-FBE engine may exhibit a
MIL "ON" condition with Diagnostic Trouble Codes (DTCs) P0171 / P0174 (System too Lean Bank 11
Bank 2), P0172/P01 75 (System too Rich Bank 1/Bank 2), P1604 (Startability Ma/function), and/or
P1605 (Rough Idling) after attempting to start the engine. Alcohol Density Estimate values may be
high even though the vehicle was fu eled with regular fuel (EO/E10). The Engine Control Module/EC M
(SAE term: Powertrain Control Modu le/PCM) logic has been modified to reduce the possibility of this
condition occurring. Use the fol lowing repair procedu re to reprogram the ECM (PC M).
