• Warranty Information and Repair Procedure sections have been updated.
Any previous printed versions of this bulletin should be discarded.
Introduction
Some 2012-2013 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 11
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 (EO/E 10). The Engine Control Module/ECM
(SAE term: Powertrain Control Module/PCM) logic has been modified to reduce the possibility of this
condition occurring. Use the following repair procedure to reprogram the ECM (PCM).

. 2. Using Techstream, confirm one or more of the following DTCs is present:
• P1604: Startability Malfunction
• P1605: Rough Idling
• PO 171 : System Too Lean (Bank 1)
• P0172: System Too Rich (Bank 1)
• P0174: System Too Lean (Bank 2)
• P0175: System Too Rich (Bank 2)
3. If any of the DTCs listed above is present, confirm the Alcohol Density Estimate and fuel trim
values.
Is the Alcohol Density Estimate value 15% or greater and are the fuel trim values negative?
• YES • NO -
Reprogram the ECM (PCM). Go to step 4.
This bulletin does NOT apply. Continue diagnosis using the applicable Repair Manual.
