Toyota Hybrid Recalibration

Some 2012-2015 model year Toyota Sequoia  hybrid vehicles with the 3UR-FBE engine may exhibit a MIL on with 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 ECM logic has been modified to address this condition. Reprogram the ECM, reset values and add fuel.
