P109d Toyota DescriptionA Flexible Fuel Vehicle (FFV) can be used with a fuel containing a high concentration of ethyl alcohol.
This FFV uses a fuel pressure switching system which changes the fuel pressure to low or high using a fuel pressure switching valve.
The code is stored when a malfunction is detected in the fuel pressure switching valve circuit. If the voltage of the fuel pressure switching valve circuit is different from the voltage commanded by the Engine Control Module (ECM), the ECM determines that the fuel pressure switching valve circuit is open or shorted, and stores a DTC.
