Monitor Description
WARNING: This page is about a different car, the 2019 Toyota Highlander, 2018 Toyota Highlander, and 2017 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
These DTCs are stored if the fuel pressure sensor (for high pressure side) output voltage is out of the standard range due to an open or short in the sensor circuit.
Example:
When the sensor output voltage is less than 0.2933 V, or higher than 4.9 V for 3 seconds or more, the ECM stores a DTC.
