Prius Update

Some 2010-2015 Toyota Prius, 2012-2016 Prius PHV and 2012-2016 Prius V vehicles equipped with a 2ZR-FXE engine may exhibit a MIL on with DTCs P2111 (throttle actuator control system) and P0A0F (engine failed to start) present when ambient temperatures are below 23 degrees Fahrenheit.

This intake manifold assembly has been improved, and the ECM logic has been modified to reduce the possibility of this condition.

Check the part number of the intake manifold. This can be found on top of the intake runner #4. If the current P/N is 17120-37090, do not replace the intake manifold, as this P/N represents the improved manifold.

Note: According to Toyota, the ECM should not be replaced as part of this fix. The ECU should be recalibrated with the new calibration ID, available from Toyota. Check the P/N of the ECU. If the new P/N is found, there is no need to replace the ECU.
